## 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-daily-foreign-exchange-rate-lookup-f5539e89
```

## When to prefer this

Choose this endpoint when you need an authoritative, official daily reference exchange rate published by the European Central Bank — ideal for financial reporting, invoice reconciliation, compliance, or informational currency conversion among 30 major currencies. Prefer it over live trading rate APIs when regulatory or accounting accuracy matters more than real-time bid/ask spreads.

## Known failure modes

- Same currency for both 'from' and 'to' may return a rate of 1 or an error
- Currency codes not in the supported 30-currency list will be rejected
- ECB may not publish rates on weekends or public holidays, potentially returning the most recent available rate
- Amount exceeding the maximum allowed value will be rejected
- Missing required 'from' or 'to' parameters will result in a validation error

## How this service works

Use when you need an official daily reference exchange rate between two of 30 major currencies (EUR, USD, BRL, GBP, JPY, CNY...) from the European Central Bank, optionally converting an amount. Returns the rate date. Reference rates are for information, not trading quotes.

## Output

Returns the official ECB daily reference exchange rate between the two specified currencies, the date of the rate, and optionally the converted amount if an input amount was provided. Rates are informational reference rates, not live trading quotes.
