# Pocket Network – Kaia Mainnet JSON-RPC

> Pocket Network – Kaia Mainnet JSON-RPC is a paid API for AI agents from agent.pocket.network, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Provides read-only Ethereum-compatible JSON-RPC access to Kaia mainnet (the merged Klaytn and Finschia chain) via Pocket Network's decentralised supplier set, with pay-per-request pricing in USDC.

## Facts

- Endpoint: POST https://agent.pocket.network/v1/kaia?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/pocket-network-kaia-mainnet-json-rpc-2484f9c8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Re3s1MlPZjyoaIgI1k8Qj

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pocket-network-kaia-mainnet-json-rpc-2484f9c8 -d '<json body>'
```

Example prompt: What's the current KAIA balance of wallet 0xAbC123...789 on Kaia mainnet? Use eth_getBalance with the latest block.

## When to prefer this

Choose this endpoint when you need decentralised, censorship-resistant read access to Kaia mainnet (the merged Klaytn/Finschia chain) without signing up for an account or managing API keys. It is ideal for agents that need pay-as-you-go, per-request billing in USDC and want the redundancy of Pocket Network's distributed node supplier set rather than a single centralised RPC provider.

## Known failure modes

- Invalid JSON-RPC method name returns an error object with code -32601 (method not found)
- Write methods (eth_sendRawTransaction, etc.) are rejected as this is a read-only endpoint
- Malformed params return code -32602 (invalid params)
- Node supplier temporarily unavailable may return a 503 or timeout
- Insufficient USDC balance causes payment failure and request rejection

## How this service works

Pay-per-call access to Pocket Network services. No account, no API key.

## Output

A standard Ethereum JSON-RPC response object containing a 'result' field with the requested on-chain data (balance, block, receipt, logs, etc.) or an 'error' field with code and message if the call fails. Data is sourced from Pocket Network's decentralised Kaia node suppliers.
