## 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 vytrel-control-crypto-price-de65c65a
```

Example prompt: What's the current Bitcoin price in USD — give me the bid, ask, and spread from Coinbase right now?

## When to prefer this

Choose this endpoint when you need a low-cost, machine-payable real-time BTC-USD price quote with bid/ask spread detail sourced directly from Coinbase Exchange, especially in x402-compatible agent workflows that require a settlement receipt alongside the price data.

## Known failure modes

- Upstream Coinbase Exchange REST API unavailable — ok:false or HTTP 503
- x402 payment not settled — request rejected before data is returned
- Stale or missing ticker data — latency_ms unusually high or timestamp lagged
- Invalid product_id — no matching ticker returned
- Rate limiting on the upstream Coinbase endpoint

## How this service works

Machine-payable URL observations and Base wallet reads, with x402 settlement receipts.

## Output

A JSON object containing the current Bitcoin mid price, bid, ask, spread in basis points, the Coinbase product ID (BTC-USD), the source label, a schema version string, observed timestamp, and the latency in milliseconds of the upstream Coinbase ticker call. The 'ok' flag confirms a successful fetch.
