## 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

Example prompt: What are today's official ECB reference rates for EUR against USD, GBP, and JPY?

## When to prefer this

Use this endpoint when you need official ECB-published foreign exchange reference rates in structured JSON format, especially for EUR-based conversions in European financial, accounting, or invoicing workflows. Prefer this over unofficial or aggregated FX providers when regulatory or audit compliance requires ECB-sourced rates. Best for daily batch processes, invoicing, or financial reporting rather than real-time trading.

## Known failure modes

- Invalid currency code returns an error or empty rates object
- Unsupported base currency (ECB only publishes EUR-based rates natively) may return an error
- Weekend or ECB holiday means rates may be up to 3 days old (last working day rates served)
- Rate limiting or payment failure returns 402 Payment Required
- Malformed symbols parameter returns 400 Bad Request
