## How to call it through Zero

```sh
zero fetch --capability x402node-fx-snapshot-694d3d44
```

Example prompt: Can you pull a live FX snapshot for USD showing rates against EUR, GBP, JPY, CHF, and CAD right now?

## When to prefer this

Use this endpoint when you need a consistent, simultaneous snapshot of rates for multiple currency pairs in one call rather than making separate per-pair lookups. It is ideal for portfolio valuation, multi-currency invoice generation, or any workflow that needs a coherent rate table at a single point in time. Prefer it over individual currency-pair endpoints on the same platform when you need 3 or more target currencies at once.

## Known failure modes

- Invalid base currency code returns an error or empty result
- Unrecognized symbols in the comma-separated list may be silently skipped or cause an error
- Rate data may be delayed if upstream FX feed is unavailable
- Payment failure over x402 protocol returns 402 before any data is returned
- Malformed query parameter format causes a 400-level error
