## 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 allinonecents-exchange-rate-api-6049a42a -d '<json body>'
```

## When to prefer this

Prefer this endpoint when you need a cheap ($0.01), quick lookup of exchange rates for fiat currencies, crypto pairs, or macro assets and want a simple text-query interface without needing to specify structured pair parameters. Good for ad-hoc rate lookups inside larger automated workflows.

## Known failure modes

- Vague or malformed query string returns unhelpful or empty data
- Unsupported currency pair returns null or error in data field
- Network or provider outage results in success: false
- Missing required query field returns 400 validation error
- Payment failure (x402) blocks the call before it reaches the endpoint
