## 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 nodeflare-unichain-rpc-chain-130-52d04e94 -d '<json body>'
```

Example prompt: Can you call eth_getLogs on Unichain (chain 130) to fetch all Transfer events from the contract 0xAbCd... between blocks 1000000 and 1001000?

## When to prefer this

Choose this endpoint when you need reliable, archive-depth RPC access to Unichain (chain 130) without setting up an account or API key, and want pay-as-you-go USDC billing suitable for AI agents. Ideal for indexing, event queries, transaction simulation, and debug/trace calls that most free-tier RPC providers block or rate-limit.

## Known failure modes

- Insufficient USDC payment causes 402 Payment Required response
- Invalid JSON-RPC method name returns error code -32601 Method not found
- Malformed params array causes -32602 Invalid params error
- Requested block or state not available on non-archive node returns null or error
- Network timeout on heavy trace/debug calls
- Unsupported method on this chain returns error

## How this service works

Unichain RPC (chain 130): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.

## Output

A standard JSON-RPC 2.0 response object containing the result field for the requested method (e.g. hex-encoded values, log arrays, trace objects, call return data) or an error object with code and message if the call fails.
