## 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 basebrain-ai-exchange-rates-a6f85a74 -d '<json body>'
```

Example prompt: Can you fetch the current exchange rate between USD and EUR for me?

## When to prefer this

Use this endpoint when you need programmatic access to currency exchange rates and are operating in a pay-per-call x402 payment context. It is suitable for lightweight, on-demand forex lookups where you do not need a dedicated subscription to a major forex data provider.

## Known failure modes

- Invalid or unsupported currency pair returns an error
- Payment not processed (402) if USDC payment is not included
- Malformed request body returns a validation error
- Upstream exchange rate provider unavailable causes service errors
- Rate limiting if too many requests are made in a short period
