  title: Starknet JSON-RPC Starknet JSON RPC API
  version: 0.8.0
  description: 'Starknet is a permissionless Ethereum Layer 2 validity rollup developed

    by StarkWare. Full nodes (Pathfinder, Juno, Papyrus) and infrastructure

    providers (Infura, Alchemy, Blast, Nethermind) implement the versioned

    Starknet JSON-RPC specification. All methods are invoked via a single

    POST endpoint and follow the JSON-RPC 2.0 envelope.


    Methods enumerated from the upstream specification at

    https://github.com/starkware-libs/starknet-specs (starknet_api_openrpc.json).
