## 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 fitze-x402-seller-exchange-rates-be7aa90f -d '<json body>'
```

Example prompt: What are today's exchange rates from USD to EUR, GBP, JPY, and CNY?

## When to prefer this

Choose this endpoint when you need live foreign exchange rates for one or more currency pairs without managing API keys or accounts — the x402 micropayment model ($0.002 USDC) makes it ideal for per-call agentic workflows. Prefer this over full forex APIs when lightweight, accountless access is sufficient and you only need spot rates rather than historical data or complex derivatives.

## Known failure modes

- Invalid currency code returns an error or omits the rate from the result
- Network or upstream provider outage may return a 5xx error
- Malformed comma-separated 'to' string may cause parsing failures
- Stale data if upstream provider hasn't refreshed recently — check updated_at field

## How this service works

Pay-per-call AI/data tools settled in USDC on Base via x402. No account, no API key — pay the 402 and receive the result. All endpoints also accept a bare hostname without the https:// prefix.

## Output

A JSON object containing the base currency, a map of target currency codes to their current exchange rates (e.g. EUR: 0.921), the data source (open.er-api.com), and an updated_at timestamp indicating when the rates were last refreshed.
