Ankr.py SDK

Ankr.py SDK is a compact Python library that enables interaction with Advanced API.

Get started

Install the latest package stored on PyPi (opens in a new tab).

pip install ankr-sdk

Initialize the SDK.

Sign in to the RPC Service (opens in a new tab) platform, get your individual endpoint from the Advanced API (opens in a new tab) pane, and provide it to the AnkrWeb3 class.

from ankr import AnkrWeb3
 
ankr_w3 = AnkrWeb3("YOUR_ENDPOINT")

Use the SDK to call the methods supported:

Node API

eth_block = ankr_w3.eth.get_block("latest")
bsc_block = ankr_w3.bsc.get_block("latest")
polygon_block = ankr_w3.polygon.get_block("latest")

NFT API

from ankr.types import Blockchain
 
nfts = ankr_w3.nft.get_nfts(
    blockchain=[Blockchain.ETH, Blockchain.BSC],
    wallet_address="0x0E11A192d574b342C51be9e306694C41547185DD",
    filter=[
        {"0x700b4b9f39bb1faf5d0d16a20488f2733550bff4": []},
        {"0xd8682bfa6918b0174f287b888e765b9a1b4dc9c3": ["8937"]},
    ],
)

Token API

assets = ankr_w3.token.get_account_balance(
    wallet_address="0x77A859A53D4de24bBC0CC80dD93Fbe391Df45527"
)

Query API

logs = ankr_w3.query.get_logs(
    blockchain="eth",
    from_block="0xdaf6b1",
    to_block=14350010,
    address=["0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"],
    topics=[
        [],
        ["0x000000000000000000000000def1c0ded9bec7f1a1670819833240f027b25eff"],
    ],
    decode_logs=True,
)
