## 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 premiumrewards-vip-fx-currency-converter-d295634a
```

Example prompt: Convert 250 US dollars to Japanese yen for me using current exchange rates.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call currency conversion without a subscription — ideal for agent workflows that only occasionally need FX lookups and want to avoid rate-plan commitments. The x402 micropayment model ($0.01 USDC per call on Base) makes it suitable for low-volume or sporadic use cases where a traditional API key would be wasteful.

## Known failure modes

- Invalid or unsupported currency code returns an error response
- Missing required query parameters (from, to, amount) result in a bad request error
- Unpaid request returns HTTP 402 Payment Required — USDC payment on Base network must be completed first
- Network or upstream rate-feed outage may cause service unavailability
- Non-numeric amount value returns a validation error

## How this service works

Four paid HTTP lookups. USDC on Base. Unpaid GET returns 402.

## Output

A plain-text string containing the converted currency amount based on current exchange rates for the specified source currency, target currency, and input amount.
