## 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 endpointsxrt-exchange-rates-api-21ef0db3 -d '<json body>'
```

Example prompt: What are the current exchange rates for USD as the base currency?

## When to prefer this

Use this endpoint when you need live currency exchange rates and are already operating in a pay-per-call x402 ecosystem on Base chain, or when other sibling endpoints on EndpointsXRT are already being used and consistency matters. Best for lightweight, single-base-currency lookups rather than bulk historical data.

## Known failure modes

- Invalid or unsupported base currency code returns an error
- Network or upstream rate provider unavailability causes failure
- Malformed request body missing the base field may return a 400 error
- Payment failure on Base chain (x402) results in a 402 response before data is returned
