## 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 santyvv-data-chain-code-lookup-e045ea89
```

Example prompt: What chain data does the code 'base' map to — look it up from the on-chain data API without needing an API key?

## When to prefer this

Choose this endpoint when you need quick, keyless lookup of blockchain chain code metadata without setting up API accounts, and are comfortable paying $0.01 USDC per call via the x402 protocol on Base. Ideal for agents or lightweight integrations that need occasional chain data without API key management overhead.

## Known failure modes

- Invalid or unrecognized chain code returns an error or empty result
- Payment failure via x402 protocol blocks the request (402 response)
- Upstream public data provider unavailability may cause degraded or fallback responses
- Missing required query parameters results in a 400 bad request
- Rate or network issues on Base blockchain may delay payment confirmation

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

A normalized JSON response containing metadata and details associated with the requested blockchain chain code, such as network name, chain ID, and related on-chain attributes. Response is edge-cached and sourced from multiple public data providers.
