## 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 btc-to-usd-live-price-converter-66c06f0b

## When to prefer this

Use this endpoint when you need a quick, real-time BTC-to-USD conversion with a single live price lookup. It is ideal for agents that need to express a Bitcoin wallet balance, transaction amount, or portfolio value in USD without building their own price-feed integration. Prefer this over generic crypto data APIs when you only need BTC/USD and want a low-latency, pay-per-call approach with no subscription required.

## Known failure modes

- Invalid or non-numeric amount parameter returns an error
- Missing amount parameter may default to 1 or return a validation error
- Upstream price feed unavailability could cause a 503 or stale price
- Rate limiting may occur if the endpoint is called too frequently without payment
