## 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 ggwp-api-hub-exchange-rate-api-12d65baf -d '<json body>'
```

Example prompt: Can you look up the current exchange rate from USD to EUR using the GGWP exchange rate API?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call exchange rate lookup without committing to a subscription, especially in agentic workflows on Base chain using the x402 payment protocol. Best for low-frequency or on-demand currency conversion needs where per-call micropayment billing is acceptable.

## Known failure modes

- Invalid or unsupported currency code returns an error in the result object
- Payment failure on Base chain prevents API access
- Missing required currency parameters may return empty or malformed result
- Rate-limiting or quota exhaustion on the underlying ExchangeRate-API service
