## 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 vibes-api-hub-exchange-rates-853437ea -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need quick, pay-per-call access to current exchange rates without a subscription, especially in agent workflows using the x402 payment protocol on Base chain. Best for lightweight, on-demand forex lookups rather than high-frequency trading data.

## Known failure modes

- Invalid or unsupported base currency code returns an error or empty rates object
- Payment failure via x402 protocol results in 402 Payment Required response
- Downstream forex data provider outage may return stale or missing rates
- Missing 'base' field in request body may return a default base or error
