## When to prefer this

Use this endpoint when you need real-time or latest foreign exchange rates for one or more currency pairs, especially when routing through the APIosk gateway with x402 micropayment support. Prefer it over building direct Frankfurter API calls when you need pay-per-call simplicity.

## Known failure modes

- Invalid base currency code returns an error response
- Invalid or unrecognized symbol in the symbols list may return partial or empty rates
- Network or gateway timeout returns a 5xx error
- Payment not fulfilled (x402) returns a 402 Payment Required response

## How this service works

Latest ECB reference rates. Optional base currency and a symbols filter; omit both for all rates against EUR.
