# Kaia Mainnet JSON-RPC

`POST /v1/kaia`

## Request

- Base URL: `https://agent.pocket.network`
- URL: `https://agent.pocket.network/v1/kaia`
- Auth: none required

Read-only JSON-RPC access to Kaia mainnet, the Klaytn and Finschia merged chain, served by the Pocket Network decentralised supplier set. Pay per request in USDC; no account, no API key.

## Request body

- object
  - `method` string, required: JSON-RPC read method, e.g. eth_getBalance
  - `params` unknown

## Response `200`

The upstream response, served after payment settles.

- object: JSON-RPC 2.0 response envelope. Exactly one of `result` or `error` is present. `result` takes the shape the called method defines: hex-encoded quantities and byte strings per the Ethereum JSON-RPC specification, an object for block and receipt reads.
  - `jsonrpc` string: The protocol version, always "2.0"
  - `id` unknown
  - `result` unknown
  - `error` object: Present instead of `result` when the call failed
    - `code` integer: A JSON-RPC 2.0 error code
    - `message` string
    - `data` unknown

## Other responses

- `400`: Malformed request.
- `402`: Payment required. The x402 v2 terms are in the PAYMENT-REQUIRED header and, identically, in this body; sign the chosen option and retry with the PAYMENT-SIGNATURE header. The receipt arrives in PAYMENT-RESPONSE.
- `503`: This service is not currently available to serve.
