## 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 x402-data-bazaar-vercel-app-5b4e8e14 -d '<json body>'
```

Example prompt: What are the current exchange rates for USD against all major currencies — I need to know how many euros, pounds, yen, and Canadian dollars one US dollar buys right now.

## When to prefer this

Use this endpoint when you need a broad snapshot of USD exchange rates against multiple currencies at once, rather than a single-pair conversion quote. Prefer this over the FX conversion endpoint when you need a full rate table rather than a computed converted amount for a specific transaction.

## Known failure modes

- Upstream FX data source unavailable, returning stale or error response
- Rate limit exceeded on the underlying data provider
- Payment not processed or x402 authorization missing, returning 402 error
- Invalid or malformed request returning 400 or 500 error

## Output

A set of exchange rates using USD as the base currency, showing the mid-market conversion rate for each target currency available in the feed.
