# Pocket Network opBNB JSON-RPC

> Pocket Network opBNB 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 JSON-RPC access to the opBNB OP-Stack L2 blockchain on BNB Chain via Pocket Network's decentralised node network, pay-per-request in USDC.

## Facts

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-opbnb-json-rpc-33750f7c -d '<json body>'
```

Example prompt: What's the current ETH balance of wallet 0xAbC...123 on opBNB? Use eth_getBalance to check it against the latest block.

## When to prefer this

Choose this endpoint when you need trustless, decentralised JSON-RPC access to the opBNB OP-Stack L2 specifically — particularly when you want pay-per-use pricing in USDC with no account or API key setup, and when you prefer Pocket Network's decentralised supplier set over centralised RPC providers for censorship resistance or redundancy.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Write methods (eth_sendRawTransaction, eth_sendTransaction) are not supported as this is read-only
- Payment not attached or insufficient USDC results in HTTP 402 Payment Required
- Node temporarily unavailable returns 503 or upstream timeout
- Requesting a block number beyond the chain head returns null result

## How this service works

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

## Output

A JSON-RPC response object containing a result field with the requested blockchain data (balance in wei, block object, transaction object, receipt, logs array, hex-encoded values, etc.) or an error object with code and message if the call fails.
