## 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 usd-to-gbp-currency-converter-x402node-f9426350

## When to prefer this

Use this endpoint when you need to convert a specific USD amount to GBP using a live exchange rate and want the numeric result directly. Prefer this over a rate-only endpoint when you need the computed conversion result for a given amount, not just the raw rate.

## Known failure modes

- Upstream forex data source unavailability could cause stale or missing rates
- Non-numeric amount value may cause a parsing error
- Network timeout if live rate provider is slow
