## 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 ecb-euro-reference-exchange-rates-currency-conversion-0a5fefcb -d '<json body>'
```

Example prompt: What's the official ECB euro reference rate for converting 1,200 EUR to USD today? Give me the converted amount and the reference date.

## When to prefer this

Choose this endpoint when you need the authoritative, official ECB euro reference rate rather than a commercial FX rate or mid-market approximation. Ideal for compliance, invoicing, accounting, and regulatory contexts where the ECB fixing is the required standard. Also use when you need a full snapshot of all ~30 ECB-published rates in a single call. Prefer the sibling historical endpoint when a past date's rate is needed.

## Known failure modes

- Unsupported currency code returns null or error — ECB only covers ~30 currencies
- Missing required body fields (type, method, bodyType) cause request failure
- ECB data may not update on weekends or public holidays, so fecha_referencia may lag
- Malformed amount (non-numeric importe) causes computation failure
- Rate temporarily unavailable if ECB has not yet published the day's fixing

## How this service works

Official European Central Bank euro reference exchange rates (about 30 currencies) and currency conversion between any two of them, with reference date.

## Output

Returns a JSON object with: the source currency (de), target currency (a), base currency (base), the exchange rate (tipo), the converted amount (resultado), the original amount (importe), the ECB reference date (fecha_referencia), the source label (fuente), any notes (nota), and — when no target currency is specified — a map of all ~30 ECB rates (tipos).
