## 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 avent-tech-currency-converter-e1a16bf1
```

Example prompt: What's 250 USD worth in GBP right now? Convert it and give me the exchange rate.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call currency conversion with a clear ISO 4217 interface and a dated exchange rate. It is well-suited for agents that need spot-rate conversions for financial summaries, invoicing, or reporting without requiring an API key subscription.

## Known failure modes

- Invalid or unsupported ISO 4217 currency code returns an error
- Missing required query parameters (amount, from, to) returns a 400-level error
- Amount not parseable as a number may cause a validation error
- Stale or unavailable rate data may return an older rateDate
