## 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 anokha-web-tools-currency-exchange-rate-lookup-d05ae21c
```

Example prompt: What's the current exchange rate from USD to EUR and GBP, and how much would $250 be in each?

## When to prefer this

Prefer this endpoint when you need a pay-per-call, no-API-key FX rate lookup paid with USDC on Base via x402. It is ideal for AI agents that need lightweight, on-demand currency conversion without managing subscriptions or API credentials. Not suited for high-frequency trading data or historical rate series.

## Known failure modes

- Invalid or unsupported ISO currency code returns an error or missing rate
- Missing required 'base' or 'to' query parameter may return a 400-level error
- Payment failure via x402 prevents the call from completing
- Stale or unavailable rate data may result in an outdated date field
- Network or service timeout returns no response
