## 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-agentutility-ai-3e01ac10 -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR, GBP, and JPY, and also tell me how much 1000 USD is worth in euros right now?

## When to prefer this

Choose this endpoint when you need reliable, ECB-sourced exchange rates for 30+ major currency pairs with no commercial use restrictions, especially when historical rates by date or optional direct amount conversion in a single call is needed. Prefer over general web searches when structured, machine-readable rate data is required.

## Known failure modes

- Unsupported or misspelled currency code returns an error
- Future dates are invalid — only 'latest' or past dates accepted
- Historical data may not be available before ECB tracking began (pre-1999 for EUR)
- Invalid date format (not YYYY-MM-DD) returns a parsing error
- Micro-payment failure ($0.002 USDC) blocks the request if wallet is underfunded

## How this service works

Exchange rates. Latest or historical FX rates between currencies, sourced from the European Central Bank (Frankfurter API). 30+ currency pairs. Optional amount conversion. No commercial restrictions. Specify a base currency (default USD), an optional quote currency or list, an optional date (YYYY-MM-DD or 'latest'), and an optional amount to also receive a converted value when a single quote is supplied.

## Output
