## 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 24k-labs-fx-rate-converter-c9680ffd -d '<json body>'
```

Example prompt: Convert 250 USD to EUR using the latest ECB reference rate.

## When to prefer this

Choose this endpoint when you need a trustworthy, official ECB reference rate for currency conversion without requiring your own API key. It is ideal for informational, compliance-friendly, or EU-context conversions. Prefer it over commercial FX APIs when you don't need real-time mid-market or interbank rates and ECB coverage (major and European currencies) is sufficient. Not suitable for crypto, exotic pairs, or live trading rates.

## Known failure modes

- Unsupported currency code returns an error (ECB only covers a limited set of ~32 currencies, no crypto or exotic pairs)
- Invalid or missing amount field returns a validation error
- ECB rate feed temporarily unavailable may cause a service error
- Stale rate if ECB has not yet published the day's rate (rates update ~16:00 CET on business days)

## How this service works

Convert an amount between currencies at the latest ECB reference rate (Frankfurter, keyless).

## Output

Returns the converted amount in the target currency, the exchange rate used, the currency pair, and the timestamp of the ECB reference rate applied.
