## 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 losbeto-fx-rate-lookup-ac21eb1e
```

Example prompt: What's the current exchange rate with USD as the base currency?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call foreign exchange rate lookup with no subscription required, especially in agentic workflows that pay via x402/USDC microtransactions. It is ideal for one-off pricing conversions rather than bulk historical data or streaming tick feeds.

## Known failure modes

- Missing required 'base' query parameter returns an error
- Unsupported or misspelled currency code may return null or error
- Upstream exchangerate-api.com unavailability causes failed fetch
- Payment of $0.01 USDC not fulfilled results in HTTP 402 response
