Ethereum Beacon
Available for Premium users only.
Ethereum Beacon API is available on Web3 API platform (opens in a new tab) upon switching on the Beacon toggle.
The Beacon Chain is a consensus layer that introduced a proof-of-stake (opens in a new tab) to Ethereum. The Beacon Chain mechanism is responsible for creating new blocks, making sure those new blocks are valid, and rewarding validators with ETH for keeping the network secure.
In order for your Web3 application to interact with the Beacon Chain — either by reading blockchain data or sending transactions to the network — it must connect to a Beacon node. Developers interact with the blockchain using the methods provided by the API.
Beacon API uses the REST interface for querying, responses come in JSON format (opens in a new tab).

}POST /eth/v1/beacon/blinded_blocks
Publishes a signed block.
Instructs the beacon node to use the components of the SignedBlindedBeaconBlock to construct and publish a SignedBeaconBlock by swapping out the transactions_root for the corresponding full list of transactions. The beacon node should broadcast a newly constructed SignedBeaconBlock to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202). Before Bellatrix, this endpoint will accept a SignedBeaconBlock.
Parameters
Eth-Consensus-Version(string; header): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): TheSignedBlindedBeaconBlockobject composed ofBlindedBeaconBlockobject (produced by beacon node) and validator signature.

broadcast_validation(string; query): level of validation that must be applied to a block before it is broadcast. Possible values:gossip(default): lightweight gossip checks only.consensus: full consensus checks, including validation of all signatures and blocks fields except for the execution payload transactions.consensus_and_equivocation: the same asconsensus, with an extra equivocation check immediately before the block is broadcast. If the block is found to be an equivocation it fails validation.
-
Eth-Consensus-Version(string; header; required): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb. -
<request body>(required): TheSignedBlindedBeaconBlockobject composed ofBlindedBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v1/beacon/blocks
Publishes a signed block.
Instructs the beacon node to broadcast a newly signed beacon block to the beacon network, to be included in the beacon chain. A success response (20x) indicates that the block passed gossip validation and was successfully broadcast onto the network. The beacon node is also expected to integrate the block into state, but may broadcast it before doing so, thus to aid timely delivery of the block. Should the block fail full validation, a separate success response code (202) is used to indicate that the block was successfully broadcast but failed integration. After Deneb, this additionally instructs the beacon node to broadcast all given blobs.
Parameters
Eth-Consensus-Version(string; header): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): theSignedBeaconBlockobject composed of theBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v2/beacon/blocks
Publishes a signed block.
Instructs the beacon node to broadcast a newly signed beacon block to the beacon network, to be included in the beacon chain. A success response (20x) indicates that the block passed gossip validation and was successfully broadcast onto the network. The beacon node is also expected to integrate the block into the state, but may broadcast it before doing so, so as to aid timely delivery of the block. Should the block fail full validation, a separate success response code (202) is used to indicate that the block was successfully broadcast but failed integration. After Deneb, this additionally instructs the beacon node to broadcast all given blobs. The broadcast behaviour may be adjusted via the broadcast_validation query parameter.
Parameters
broadcast_validation(string; query): level of validation that must be applied to a block before it is broadcast. Possible values:
gossip(default): lightweight gossip checks only.consensus: full consensus checks, including validation of all signatures and blocks fields except for the execution payload transactions.consensus_and_equivocation: the same asconsensus, with an extra equivocation check immediately before the block is broadcast. If the block is found to be an equivocation it fails validation.
Eth-Consensus-Version(string; header): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): theSignedBeaconBlockobject composed of theBeaconBlockobject (produced by beacon node) and validator signature.

Subscribes to Beacon node events.
Provides endpoint to subscribe to beacon node Server-Sent-Events stream. Consumers should use eventsource (opens in a new tab) implementation to listen on those events.
Servers may send SSE comments beginning with : for any purpose, including to keep the event stream connection alive in the presence of proxy servers.
Parameters
topics(array[string]; query; required): event types to subscribe to; available values :head,block,block_gossip,attestation,voluntary_exit,bls_to_execution_change,proposer_slashing,attester_slashing,finalized_checkpoint,chain_reorg,contribution_and_proof,light_client_finality_update,light_client_optimistic_update,payload_attributes,blob_sidecar.
Request example
curl -X GET "https://rpc.ankr.com/premium-http/eth_beacon/{your_token}/eth/v1/events" \
-H "Accept: text/event-stream"Responses
Code 200: Opened SSE stream.
Head event:
The node has finished processing, resulting in a new head. previous_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) and current_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch) - 1). Both dependent roots use the genesis block root in the case of underflow.

The node has computed new payload attributes for execution payload building.
This event gives block builders and relays sufficient information to construct or verify a block at proposal_slot. The meanings of the fields are:
version: the identifier of the beacon hard fork at proposal_slot, e.g. "bellatrix", "capella".proposal_slot: the slot at which a block using these payload attributes may be built.parent_block_root: the beacon block root of the parent block to be built upon.parent_block_number: the execution block number of the parent block.parent_block_hash: the execution block hash of the parent block.proposer_index: the validator index of the proposer atproposal_sloton the chain identified byparent_block_root.payload_attributes: beacon API encoding ofPayloadAttributesV<N>as defined by the execution-apis specification. The versionNmust match the payload attributes for the hard fork matchingversion. The beacon API encoded object must have equivalent fields to its counterpart inexecution-apiswith two differences: 1)snake_caseidentifiers must be used rather thancamelCase; 2) integers must be encoded as quoted decimals rather than big-endian hex.
The frequency at which this event is sent may depend on beacon node configuration. The fee recipient may also be set via beacon node config, but should likely be ignored by block builders and most other API consumers.

Validator
Endpoints intended for validator clients.
POST /eth/v1/validator/duties/attester/{epoch}
Retrieves attester duties.
Requests the beacon node to provide a set of attestation duties, which should be performed by validators, for a particular epoch. Duties should only need to be checked once per epoch, however a chain reorganization (of > MIN_SEED_LOOKAHEAD epochs) could occur, resulting in a change of duties. For full safety, you should monitor head events and confirm the dependent root in this response matches:
- event.previous_duty_dependent_root when
compute_epoch_at_slot(event.slot) == epoch - event.current_duty_dependent_root when
compute_epoch_at_slot(event.slot) + 1 == epoch - event.block otherwise
The dependent_root value is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) or the genesis block root in the case of underflow.
Parameters
epoch(string; path; required): should only be allowed one epoch ahead.<request body>(required): an array of the validator indices for which to obtain the duties:

}GET /eth/v3/validator/blocks/{slot}
Produces a new block, without signature.
Requests a beacon node to produce a valid block, which can then be signed by a validator. The returned block may be blinded or unblinded, depending on the current state of the network as decided by the execution and beacon nodes.
The beacon node must return an unblinded block if it obtains the execution payload from its paired execution node. It must only return a blinded block if it obtains the execution payload header from an MEV relay.
Metadata in the response indicates the type of block produced, and the supported types of block will be added to as forks progress.
Parameters
slot(string; path; required): the slot for which the block should be proposed.randao_reveal(string; hex; query; required): the validator's randao reveal value.graffiti(string; hex; query): an arbitrary data validator to include in the block.skip_randao_verification(query): skip verification of therandao_revealvalue. If this flag is set then therandao_revealmust be set to the point at infinity (0xc0..00). This query parameter is a flag and does not take a value.builder_boost_factor(string; query):
Percentage multiplier to apply to the builder's payload value when choosing between a builder payload header and payload from the paired execution node. This parameter is only relevant if the beacon node is connected to a builder, deems it safe to produce a builder payload, and receives valid responses from both the builder endpoint and the paired execution node. When these preconditions are met, the server MUST act as follows:
- if
exec_node_payload_value >= builder_boost_factor * (builder_payload_value // 100), then return a full (unblinded) block containing the execution node payload. - otherwise, return a blinded block containing the builder payload header.
Servers must support the following values of the boost factor which encode common preferences:
builder_boost_factor=0: prefer the execution node payload unless an error makes it unviable.builder_boost_factor=100: default profit maximization mode; choose whichever payload pays more.builder_boost_factor=2**64 - 1: prefer the builder payload unless an error or beacon node health check makes it unviable.
Servers should use saturating arithmetic or another technique to ensure that large values of the builder_boost_factor do not trigger overflows or errors. If this parameter is provided and the beacon node is not configured with a builder then the beacon node MUST respond with a full block, which the caller can choose to reject if it wishes. If this parameter is not provided then it should be treated as having the default value of 100. If the value is provided but out of range for a 64-bit unsigned integer, then an error response with status code 400 MUST be returned.
Request example
curl -X GET "https://rpc.ankr.com/premium-http/eth_beacon/{your_token}/eth/v3/validator/blocks/{slot}" \
-H "Accept: application/json"Responses
Code 200: Success.
Note: The Eth-Consensus-Version header is required in response so client can deserialize returned json or ssz data more effectively.

}POST /eth/v1/validator/beacon_committee_selections
Determines if a distributed validator has been selected to aggregate attestations.
This endpoint should be used by a validator client running as part of a distributed validator cluster, and is implemented by a distributed validator middleware client. This endpoint is used to exchange partial selection proofs for combined/aggregated selection proofs to allow a validator client to correctly determine if any of its validators has been selected to perform an attestation aggregation duty in a slot. Validator clients running in a distributed validator cluster must query this endpoint at the start of an epoch for the current and lookahead (next) epochs for all validators that have attester duties in the current and lookahead epochs. Consensus clients need not support this endpoint and may return a 501.

}POST /eth/v1/validator/sync_committee_selections
Determines if a distributed validator has been selected to make a sync committee contribution.
Submit sync committee selections to a DVT middleware client. It returns the threshold aggregated sync committee selection. This endpoint should be used by a validator client running as part of a distributed validator cluster, and is implemented by a distributed validator middleware client. This endpoint is used to exchange partial selection proofs (slot signatures) for combined/aggregated selection proofs to allow a validator client to correctly determine if any of its validators has been selected to perform a sync committee contribution (sync aggregation) duty in a slot. Validator clients running in a distributed validator cluster must query this endpoint at the start of each slot for all validators that are included in the current sync committee. Consensus clients need not support this endpoint and may return a 501.

}POST /eth/v1/validator/prepare_beacon_proposer
Provides the Beacon node with proposals for the given validators.
Prepares the beacon node for potential proposers by supplying information required when proposing blocks for the given validators. The information supplied for each validator index will persist through the epoch in which the call is submitted and for a further two epochs after that, or until the beacon node restarts. It is expected that validator clients will send this information periodically, for example each epoch, to ensure beacon nodes have correct and timely fee recipient information.
Note that there is no guarantee that the beacon node will use the supplied fee recipient when creating a block proposal, so on receipt of a proposed block the validator should confirm that it finds the fee recipient within the block acceptable before signing it.
Also note that requests containing currently inactive or unknown validator indices will be accepted, as they may become active at a later epoch.

}POST /eth/v1/validator/register_validator
Provides the Beacon node with registrations for the given validators to the external builder network.
Prepares the beacon node for engaging with external builders. The information must be sent by the beacon node to the builder network. It is expected that the validator client will send this information periodically to ensure the beacon node has correct and timely registration information to provide to builders. The validator client should not sign blinded beacon blocks that do not adhere to their latest fee recipient and gas limit preferences.
Note that only registrations for active or pending validators must be sent to the builder network. Registrations for unknown or exited validators must be filtered out and not sent to the builder network.

}POST /eth/v1/validator/liveness/{epoch}
Indicates if a validator has been observed on the network.
Requests the beacon node to indicate if a validator has been observed to be live in a given epoch. The beacon node might detect liveness by observing messages from the validator on the network, in the beacon chain, from its API or from any other source. A beacon node SHOULD support the current and previous epoch, however it MAY support earlier epoch. It is important to note that the values returned by the beacon node are not canonical; they are best-effort and based upon a subjective view of the network. A beacon node that was recently started or suffered a network partition may indicate that a validator is not live when it actually is.
Parameters
epoch(string; path; required): the epoch for which liveness is being queried.<request body>(required): an array of the validator indices for which to detect liveness.

}POST /eth/v1/beacon/blocks
Publishes a signed block.
Instructs the beacon node to broadcast a newly signed beacon block to the beacon network, to be included in the beacon chain. A success response (20x) indicates that the block passed gossip validation and was successfully broadcast onto the network. The beacon node is also expected to integrate the block into state, but may broadcast it before doing so, thus to aid timely delivery of the block. Should the block fail full validation, a separate success response code (202) is used to indicate that the block was successfully broadcast but failed integration. After Deneb, this additionally instructs the beacon node to broadcast all given blobs.
Parameters
Eth-Consensus-Version(header): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix.<request body>(required): theSignedBeaconBlockobject composed of theBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v2/beacon/blocks
Publishes a signed block.
Instructs the beacon node to broadcast a newly signed beacon block to the beacon network, to be included in the beacon chain. A success response (20x) indicates that the block passed gossip validation and was successfully broadcast onto the network. The beacon node is also expected to integrate the block into the state, but may broadcast it before doing so, thus to aid timely delivery of the block. Should the block fail full validation, a separate success response code (202) is used to indicate that the block was successfully broadcast but failed integration. After Deneb, this additionally instructs the beacon node to broadcast all given blobs. The broadcast behaviour may be adjusted via the broadcast_validation query parameter.
Parameters
broadcast_validation(string; query): Level of validation that must be applied to a block before it is broadcast. Possible values:gossip(default): lightweight gossip checks only.consensus: full consensus checks, including validation of all signatures and blocks fields except for the execution payload transactions.consensus_and_equivocation: the same asconsensus, with an extra equivocation check immediately before the block is broadcast. If the block is found to be an equivocation it fails validation.
Eth-Consensus-Version(header; required): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): theSignedBeaconBlockobject composed of theBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v1/beacon/blinded_blocks
Publishes a signed block.
Instructs the beacon node to use the components of the SignedBlindedBeaconBlock to construct and publish a SignedBeaconBlock by swapping out the transactions_root for the corresponding full list of transactions. The beacon node should broadcast a newly constructed SignedBeaconBlock to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202). Before Bellatrix, this endpoint will accept a SignedBeaconBlock.
Parameters
Eth-Consensus-Version(string; header): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): theSignedBlindedBeaconBlockobject composed ofBlindedBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v2/beacon/blinded_blocks
Publishes a signed block.
Instructs the beacon node to use the components of the SignedBlindedBeaconBlock to construct and publish a SignedBeaconBlock by swapping out the transactions_root for the corresponding full list of transactions. The beacon node should broadcast a newly constructed SignedBeaconBlock to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202). Before Bellatrix, this endpoint will accept a SignedBeaconBlock. The broadcast behaviour may be adjusted via the broadcast_validation query parameter.
Parameters
broadcast_validation(string; query): level of validation that must be applied to a block before it is broadcast. Possible values:gossip(default): lightweight gossip checks only.consensus: full consensus checks, including validation of all signatures and blocks fields except for the execution payload transactions.consensus_and_equivocation: the same asconsensus, with an extra equivocation check immediately before the block is broadcast. If the block is found to be an equivocation it fails validation.
Eth-Consensus-Version(string; header, required): a version of the block being submitted, if using SSZ encoding. Available values :phase0,altair,bellatrix,capella,deneb.<request body>(required): TheSignedBlindedBeaconBlockobject composed ofBlindedBeaconBlockobject (produced by beacon node) and validator signature.

}POST /eth/v1/validator/duties/attester/{epoch}
Retrieves attester duties.
Requests the beacon node to provide a set of attestation duties, which should be performed by validators, for a particular epoch. Duties should only need to be checked once per epoch, however a chain reorganization (of > MIN_SEED_LOOKAHEAD epochs) could occur, resulting in a change of duties. For full safety, you should monitor head events and confirm the dependent root in this response matches:
- event.previous_duty_dependent_root when
compute_epoch_at_slot(event.slot) == epoch - event.current_duty_dependent_root when
compute_epoch_at_slot(event.slot) + 1 == epoch - event.block otherwise
The dependent_root value is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) or the genesis block root in the case of underflow.
Parameters
epoch(string; path; required): should only be allowed one epoch ahead.<request body>(required): an array of the validator indices for which to obtain the duties:

}GET /eth/v3/validator/blocks/{slot}
Produces a new block, without signature.
Requests a beacon node to produce a valid block, which can then be signed by a validator. The returned block may be blinded or unblinded, depending on the current state of the network as decided by the execution and beacon nodes.
The beacon node must return an unblinded block if it obtains the execution payload from its paired execution node. It must only return a blinded block if it obtains the execution payload header from an MEV relay.
Metadata in the response indicates the type of block produced, and the supported types of block will be added to as forks progress.
Parameters
slot(string; path; required): the slot for which the block should be proposed.randao_reveal(string; hex; query; required): the validator's randao reveal value.graffiti(string; hex; query): an arbitrary data validator to include in the block.skip_randao_verification(query): skip verification of therandao_revealvalue. If this flag is set then therandao_revealmust be set to the point at infinity (0xc0..00). This query parameter is a flag and does not take a value.builder_boost_factor(string; query):
percentage multiplier to apply to the builder's payload value when choosing between a builder payload header and payload from the paired execution node. This parameter is only relevant if the beacon node is connected to a builder, deems it safe to produce a builder payload, and receives valid responses from both the builder endpoint and the paired execution node. When these preconditions are met, the server MUST act as follows:
- if
exec_node_payload_value >= builder_boost_factor * (builder_payload_value // 100), then return a full (unblinded) block containing the execution node payload. - otherwise, return a blinded block containing the builder payload header.
Servers must support the following values of the boost factor which encode common preferences:
builder_boost_factor=0: prefer the execution node payload unless an error makes it unviable.builder_boost_factor=100: default profit maximization mode; choose whichever payload pays more.builder_boost_factor=2**64 - 1: prefer the builder payload unless an error or beacon node health check makes it unviable.
Servers should use saturating arithmetic or another technique to ensure that large values of the builder_boost_factor do not trigger overflows or errors. If this parameter is provided and the beacon node is not configured with a builder then the beacon node MUST respond with a full block, which the caller can choose to reject if it wishes. If this parameter is not provided then it should be treated as having the default value of 100. If the value is provided but out of range for a 64-bit unsigned integer, then an error response with status code 400 MUST be returned.
Request example
curl -X GET "https://rpc.ankr.com/premium-http/eth_beacon/{your_token}/eth/v3/validator/blocks/{slot}" \

Code 200: Success.
Note: The Eth-Consensus-Version, Eth-Execution-Payload-Blinded, Eth-Execution-Payload-Value, Eth-Consensus-Block-Value header is required in response so client can deserialize returned json or ssz data more effectively.

}POST /eth/v1/validator/prepare_beacon_proposer
Provides the Beacon node with proposals for the given validators.
Prepares the beacon node for potential proposers by supplying information required when proposing blocks for the given validators. The information supplied for each validator index will persist through the epoch in which the call is submitted and for a further two epochs after that, or until the beacon node restarts. It is expected that validator clients will send this information periodically, for example each epoch, to ensure beacon nodes have correct and timely fee recipient information.
Note that there is no guarantee that the beacon node will use the supplied fee recipient when creating a block proposal, so on receipt of a proposed block the validator should confirm that it finds the fee recipient within the block acceptable before signing it.
Also note that requests containing currently inactive or unknown validator indices will be accepted, as they may become active at a later epoch.

}GET /eth/v1/events
Subscribes to Beacon node events.
Provides endpoint to subscribe to beacon node Server-Sent-Events stream. Consumers should use eventsource (opens in a new tab) implementation to listen on those events.
Servers may send SSE comments beginning with : for any purpose, including to keep the event stream connection alive in the presence of proxy servers.
Parameters

The node has computed new payload attributes for execution payload building.
This event gives block builders and relays sufficient information to construct or verify a block at proposal_slot. The meanings of the fields are:
version: the identifier of the beacon hard fork at proposal_slot, e.g. "bellatrix", "capella".proposal_slot: the slot at which a block using these payload attributes may be built.parent_block_root: the beacon block root of the parent block to be built upon.parent_block_number: the execution block number of the parent block.parent_block_hash: the execution block hash of the parent block.proposer_index: the validator index of the proposer atproposal_sloton the chain identified byparent_block_root.payload_attributes: beacon API encoding ofPayloadAttributesV<N>as defined by the execution-apis specification. The versionNmust match the payload attributes for the hard fork matchingversion. The beacon API encoded object must have equivalent fields to its counterpart inexecution-apiswith two differences: 1)snake_caseidentifiers must be used rather thancamelCase; 2) integers must be encoded as quoted decimals rather than big-endian hex.
The frequency at which this event is sent may depend on beacon node configuration. The fee recipient may also be set via beacon node config, but should likely be ignored by block builders and most other API consumers.
