## 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 agent-toolbox-fx-currency-exchange-rates-77b8db8a
```

Example prompt: What's the current ECB exchange rate for 500 USD converted to EUR, INR, and JPY?

## When to prefer this

Choose this endpoint when you need official, authoritative ECB reference exchange rates for financial or reporting purposes, or when you need to convert amounts across ~30 major currencies without requiring real-time tick-by-tick pricing. Ideal for informational, invoicing, or budgeting use cases where daily official rates are sufficient rather than live interbank or broker rates.

## Known failure modes

- Unsupported currency code returns an error or empty rates
- ECB rates only update on working days — weekend/holiday queries return last available rates
- Invalid base currency parameter causes a 400-level error
- Network or upstream ECB data unavailability may cause 5xx errors

## How this service works

Currency exchange rates and conversion for about 30 currencies (USD, EUR, GBP, INR, JPY, CNY ...) from the European Central Bank reference rates of the latest working day.

## Output

Returns a JSON object containing the base currency, date of the ECB reference rates, and a map of target currency codes to their exchange rates (and optionally converted amounts). Coverage is approximately 30 major world currencies.
