## 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-coin-price-api-x402-0465d8b6
```

Example prompt: What's the current price of Bitcoin? Use the santyvv pay-per-call crypto price endpoint — I'm fine paying $0.01 USDC per lookup.

## When to prefer this

Choose this endpoint when you need a quick, keyless cryptocurrency price lookup and are willing to pay $0.01 USDC per call via x402. Ideal for AI agents that don't want to manage API keys or subscriptions, need normalized responses across multiple coins, and benefit from edge caching and multi-source fallback reliability. Less suitable for high-frequency trading where sub-millisecond latency matters, or for bulk batch price lookups where per-call costs would accumulate significantly.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment requirements
- Unknown or unsupported coin symbol — may return an error or empty result
- Upstream data provider outage — multi-source fallback may mitigate but could fail if all sources are down
- Malformed query parameters — returns a 400-level error
- Network timeout on edge cache miss — may result in higher latency or transient failure

## 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

Returns a normalized JSON response containing the current market price of the requested cryptocurrency, sourced from public data providers with edge caching and multi-source fallback, expressed in USD or a standard quote currency.
