  title: Ankr RPC Service (Node API) EVM API
  description: 'Ankr''s RPC Service (Node API) provides HTTPS and WebSocket JSON-RPC endpoints for

    80+ blockchain networks (EVM and non-EVM). The public endpoint is open;

    Premium and Enterprise plans use an API-key-scoped endpoint with x50 the rate

    limit of the public Node API. This specification documents the common

    EVM JSON-RPC envelope that ships behind every `https://rpc.ankr.com/{chain}` URL;

    non-EVM chains (Solana, Aptos, Stellar, etc.) expose their native JSON-RPC or REST

    surface at the same per-chain endpoint.
