## 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 trusted-information-api-fx-currency-exchange-rates-1acbda42
```

Example prompt: What's today's GBP to USD and EUR exchange rate — and how much would 250 GBP convert to in both currencies?

## When to prefer this

Choose this endpoint when you need official, ECB-sourced foreign exchange rates without API keys or sign-up, especially when billing must be pay-per-call and failed calls must not be charged. Prefer over generic FX APIs when official European Central Bank provenance matters, or when building lightweight agent workflows that need spot rates for GBP-based conversions.

## Known failure modes

- Unsupported or invalid ISO currency code returns an error
- ECB data unavailable on weekends or public holidays may return stale rates
- Missing required query parameters (from/to) may result in a bad request error
- Network or upstream Frankfurter API downtime may cause timeouts; failed calls are not charged
