## 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 fx-rates-ecb-currency-conversion-2cde20ee
```

Example prompt: Using the latest ECB reference rate, convert 500 EUR to GBP and tell me the rate and the date it was fixed.

## When to prefer this

Choose this endpoint when you need a currency conversion grounded in the official ECB reference rate with a clear fixing date — ideal for compliance, financial reporting, invoicing, or any context where the authoritative ECB source matters. Prefer over commercial FX APIs when auditability and official sourcing are required.

## Known failure modes

- Unsupported currency code — the ECB only publishes rates for 30 currencies; non-ECB currencies return an error or null result
- Missing required parameters (amount, from, or to) result in a validation error
- Rate unavailable for the current day (e.g. weekend or holiday) — the API may use the most recent available fixing
- Invalid amount (non-numeric or negative) causes a bad request response

## How this service works

Convert an amount from one currency to another at the latest ECB reference rate, with the rate and fixing date.

## Output

Returns a JSON object with the converted amount (result), the exchange rate used (rate), the fixing date (fixingDate), the source currency (from), the target currency (to), the original amount (amount), a human-readable summary, source attribution, and a disclaimer. May also include a degraded flag if the rate data is not fully fresh.
