## How to call it through Zero

```sh
zero fetch --capability api-x402node-dev-45e8fb58
```

## When to prefer this

Use this endpoint when you need real-time, ECB-authoritative forex rates for one or more currency pairs in a single call — especially for AI agents handling cross-border pricing, treasury operations, or travel cost estimation. Prefer over scraping or generic FX APIs when you need comma-separated multi-target lookups and ECB data provenance.

## Known failure modes

- Unsupported or invalid currency code returns an error
- ECB data unavailable or stale if Frankfurter upstream is down
- Malformed query parameters result in a 4xx error
- Rate limiting or payment failure returns a 402 or 429 response
