## 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 x402-utilities-hub-fx-rate-lookup-623841b9 -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR? Use the x402 FX endpoint to fetch it — I need the live rate for a payment conversion.

## When to prefer this

Choose this endpoint when you need pay-per-call FX rate lookups without a subscription, especially in agent workflows that require occasional currency conversion and want to pay micro-amounts in USDC on Base via the x402 protocol rather than maintaining a traditional API key subscription.

## Known failure modes

- Missing or invalid currency pair in queryParams returns an error
- Payment failure via x402 if USDC balance is insufficient
- Unknown or unsupported currency pair returns an error or empty result
- Malformed queryParams object causes a 400-level error
- Rate data temporarily unavailable due to upstream data source issues
