## 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 agentum-lat-fx-rates-ecb-via-frankfurter-ae3f5f31
```

Example prompt: What are the current official exchange rates from USD to EUR, BRL, and GBP right now? Use the ECB Frankfurter rates.

## When to prefer this

Choose this endpoint when you need authoritative, official exchange rates from the European Central Bank (not market/broker rates), especially for any global currency pair beyond BRL. Prefer this over Brazil-specific FX endpoints (like the sibling Selic/CDI endpoint) when you need multi-currency international rates rather than Brazil-local financial indicators.

## Known failure modes

- Invalid ISO 4217 currency code returns an error or empty rates object
- Unsupported currency pair not covered by ECB data returns missing or null rates
- Network or upstream Frankfurter API outage returns a 5xx error
- Malformed query parameters may result in a 400 bad request
