## 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 gateway-apiosk-com-exchangerate-host-currency-converter-91db0b9e
```

Example prompt: Can you convert 250 US dollars to Euros for me right now and tell me the exact converted amount and exchange rate?

## When to prefer this

Use this endpoint when you need a quick, single-call currency conversion with a concrete amount — especially when you want both the converted result and the underlying exchange rate quote in one response. Prefer this over raw exchange-rate lookup endpoints when you need the computed converted value rather than just the rate.

## Known failure modes

- Invalid or unsupported currency code returns an error or success:false
- Missing required parameters (amount, from, to) returns a 400-level error
- Amount of zero or negative may return zero or an error
- API upstream (exchangerate-host) unavailable returns a gateway error
- Payment failure (insufficient USDC) blocks the request before reaching the API

## How this service works

Convert an amount from one currency to another at the live rate; returns the computed result plus the quote used.

## Output

Returns a JSON object with: the converted result amount (e.g. 87.479), the exchange rate quote used, the Unix timestamp of the rate, and an echo of the original query (from, to, amount), plus a success flag.
