Kusama
Available for Premium users only.
Kusama API is available on Web3 API platform.
Kusama reaches end of support on Ankr RPC on 15 September 2026 and these endpoints stop answering on that date. See the changelog for the full list and what to change.
Kusama is an early release of Polkadot: a scalable, multichain network for radical innovation. Kusama serves as a proving ground that allows teams and developers to build and deploy a parachain, and experiment with Polkadot’s governance and NPoS functionality in a real environment.
The API interaction follows the JSON-RPC which is a stateless, light-weight remote procedure call (RPC) protocol. It defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in other message-passing environments. It uses JSON (RFC 4627) as data format.
