Error Responses

All endpoints may return standard JSON-RPC error responses:

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32602,
    "message": "Invalid params"
  }
}

Common Error Codes

Code

Message

Description

-32600

Invalid Request

The JSON sent is not a valid Request object

-32601

Method not found

The method does not exist / is not available

-32602

Invalid params

Invalid method parameter(s)

-32603

Internal error

Internal JSON-RPC error

Notes

All hex values should include the 0x prefix
Block heights can be specified as integers or hex strings (block tags of Ethereum-spec also works)
Response data may be truncated in documentation for readability
Large responses (like proofs) may be several MB in size
Always check for error responses before processing results
