## 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-info-3e60cc9f
```

Example prompt: Can you pull the chain info for Base mainnet — I need the chain ID, RPC endpoints, and network status — using the santyvv pay-per-call data API?

## When to prefer this

Choose this endpoint when you need normalized blockchain chain metadata without setting up API keys or accounts, especially in agent workflows requiring pay-per-call micropayments via x402 on Base. Prefer it over free-tier providers when you want zero-signup access with multi-source fallback and edge caching for reliability.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported chain identifier — returns 400 or empty/error response
- Upstream public data provider unavailable — multi-source fallback may degrade to partial data
- Rate limiting or edge cache miss causing elevated latency
- Chain not indexed by upstream providers — returns empty or null fields

## 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 object containing blockchain chain metadata such as chain ID, chain name, native currency, RPC endpoint URLs, block explorer links, and network status — aggregated from public data providers and edge-cached for fast delivery.
