## 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 santyvv-data-fx-currency-converter-466f240b
```

Example prompt: What is 750 US dollars converted to Japanese yen using the current reference rate?

## When to prefer this

Use this endpoint when you need a quick, paid reference-rate currency conversion between two fiat currencies and accuracy to the reference rate (not mid-market or real-time bid/ask) is acceptable. It sits alongside other financial data endpoints on the same host, making it convenient for agents already using this provider for crypto price or market data queries.

## Known failure modes

- Unsupported currency code returns an error or empty result
- Missing required query parameters (source currency, target currency, or amount) cause a 400 bad request
- Invalid amount format (non-numeric) causes a validation error
- Rate data unavailable for exotic or non-reference currencies
- Network timeout if upstream FX rate provider is unresponsive

## How this service works
