## 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 x402node-btc-usd-live-price-940f5232
```

Example prompt: What's the current Bitcoin price in US dollars right now?

## When to prefer this

Use this endpoint when you need a zero-parameter, single-call fetch of the current BTC/USD spot price. Ideal for agents that need to quickly check Bitcoin's dollar value without constructing any query parameters. Prefer this over general crypto APIs when you want a pay-per-use micropayment model via x402 and don't need historical data or order book depth.

## Known failure modes

- Payment failure if USDC balance is insufficient (402 response)
- Upstream price feed unavailability causing stale or missing data
- Rate limiting if called too frequently
- Network timeout if the pricing source is slow to respond
