## 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 fawaz-usd-exchange-rates-cdn-38768784 -d '<json body>'
```

Example prompt: Can you get me the latest USD exchange rates against all fiat currencies so I can see what 1 dollar is worth in euros, yen, and pesos right now?

## When to prefer this

Prefer this endpoint when you need a broad, no-parameter USD-to-many-currencies rate lookup without authentication, especially for lightweight apps, quick conversions, or when cost matters (flat $0.01 per call). Not ideal when you need real-time tick-level accuracy or rates for non-USD base currencies.

## Known failure modes

- CDN outage or cache miss may return 5xx or stale data
- Response schema may shift if upstream data source changes
- Rate data may lag real-time markets since it is CDN-cached
- No filtering by currency code — full map always returned

## How this service works

Free CDN-hosted exchange rates for USD against ~200 fiat currencies. No params; itemsPath 'usd' is the rate map. Returns JSON.

## Output

A JSON object with a top-level 'usd' key mapping to a flat dictionary of ~200 currency codes (e.g. 'eur', 'jpy', 'gbp') to their current exchange rate expressed as units of that currency per 1 USD.
