## 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-crypto-price-api-7ac138fc
```

Example prompt: What's the current Bitcoin price? Use the santyvv pay-per-call crypto price feed — I want to see if the price is consistent across venues and get the median USD value.

## When to prefer this

Choose this endpoint when you need a reliable, normalized crypto spot price without managing API keys or subscriptions. It is especially useful for AI agents that need to make occasional price checks on a pay-as-you-go basis, want multi-source validation with a divergence signal, and are already operating in a USDC/Base payment context via x402. Prefer it over raw exchange APIs when you need consensus reliability scoring without building your own aggregation layer.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment details
- Unknown or unsupported ticker symbol — may return empty or error response
- All data sources unavailable — consensus_fiable may be false or call may fail
- Network timeout from upstream data providers — edge cache may serve stale data
- Malformed query parameters — returns 400 or similar error

## 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 JSON object containing the asset ticker as key, with fields: median price in USD (precio_mediana_usd), maximum price across venues (precio_max_usd), minimum price (precio_min_usd), number of venues that responded successfully (venues_ok), percentage divergence between venues (divergencia_pct), and a boolean indicating whether consensus is reliable (consenso_fiable).
