## 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 whatchuneed-exchange-rate-api-0418e273 -d '<json body>'
```

Example prompt: What's the current exchange rate for USD against EUR, GBP, and JPY?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call currency exchange rate lookup without committing to a subscription-based forex API. Ideal for agents that need spot exchange rates infrequently or across multiple currency pairs in a single call. Best when you want multi-target rates in one request rather than making separate calls per currency pair.

## Known failure modes

- Unsupported or invalid currency code for base field returns an error
- Empty or malformed targets array may return rates for all available currencies or an error
- Network/upstream data provider outage causes stale or unavailable rates
- Rate limiting may occur with high-frequency calls
