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 gocreative-crypto-chain-lookup-30d0fa34
```

Example prompt: Can you look up the chain details for Ethereum mainnet — I need the chain ID, native currency, and official RPC endpoints from GoCreative's crypto chain data?

## When to prefer this

Use this endpoint when you need authoritative metadata about a specific blockchain network — such as chain ID, RPC URLs, or block explorer links — without signing up for an API key. Ideal for agents needing on-demand chain lookups at $0.01 per call via x402/USDC, especially when integrating with multi-chain dApps or cross-chain workflows.

## Known failure modes

- Unknown or unsupported chain identifier returns 404 or empty result
- Invalid chain argument format causes 400 bad request
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Network timeout if chain registry is temporarily unavailable
- Malformed chain slug returns error response

## How this service works

483,000+ pay-per-call data APIs and free tools built on official sources — finance, company & government data, FRED, Census, crypto, calculators. USDC on Base via x402, native MCP. No API key, no signup.

## Output

Returns structured metadata about the requested blockchain chain, including chain ID, chain name, native currency symbol, RPC endpoint URLs, and block explorer links, sourced from official data aggregators.
