## 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-data-hub-v2-currency-conversion-6be6b750 -d '<json body>'
```

Example prompt: Convert 500 USD to EUR and tell me how much I'd get at the current exchange rate.

## When to prefer this

Choose this endpoint when you need to convert between fiat and/or crypto currencies with a simple amount-in, amount-out call. It supports both crypto and traditional currency pairs, making it suitable for mixed fiat/crypto workflows. At $0.05 USDC per call it suits low-to-medium frequency conversion lookups rather than high-frequency trading.

## Known failure modes

- Unsupported currency code returns an error
- Invalid or non-positive amount may return validation error
- Missing required fields (from, to, amount) returns 400 Bad Request
- Payment not received or insufficient USDC results in 402 Payment Required
- Exchange rate data temporarily unavailable returns 503
