## 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 agenticweb-fx-currency-converter-ecb-rates-1fd63b40
```

Example prompt: What's the ECB euro reference rate from USD to JPY, and how much would 250 US dollars be in Japanese yen?

## When to prefer this

Use this endpoint when you need official ECB euro reference rates for currency conversion, particularly for EUR-based pairs or informational/accounting purposes rather than live trading rates. Prefer this over general FX APIs when ECB compliance or official reference rates are required.

## Known failure modes

- Unsupported or invalid ISO 4217 currency code returns an error
- ECB does not publish rates for all world currencies — non-EUR-paired or exotic currencies may be unavailable
- Rates reflect the ECB reference snapshot date, which may be one business day behind real-time market rates
- Network or service unavailability returns a non-200 response
- Missing required query parameters may return a 400 bad request

## How this service works

Currency conversion via ECB euro reference rates (informational). The underlying ECB reference rates can be obtained free of charge from https://www.ecb.europa.eu/stats/eurofxref/. Payment constitutes acceptance of the terms at https://agenticweb.nl/terms.

## Output

Returns a JSON object with the source currency (from), target currency (to), the ECB reference exchange rate (rate), the date of the ECB snapshot (as_of), the original amount, and the computed result (amount × rate).
