## 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 usd-to-jpy-currency-converter-live-rate-e5ab4627
```

Example prompt: How much is 250 US dollars in Japanese yen right now using the live exchange rate?

## When to prefer this

Use this endpoint when you need to convert a specific USD dollar amount to Japanese Yen using a live market rate, especially when you want the full conversion result (not just the rate). Prefer over a bare rate endpoint when you need the computed JPY value directly.

## Known failure modes

- Invalid or missing amount parameter returns an error
- Amount of zero or negative value may produce unexpected results
- Rate data provider temporarily unavailable leading to stale or missing rate
- Payment not fulfilled (x402 protocol) results in 402 Payment Required response

## How this service works

Convert USD to JPY at live rate. Pass ?amount=100 for value in Japanese Yen. 美元兑换日元换算。米ドルを円に換算。Convertir dólar a yen. 달러를 엔로 환전. usd to jpy convert. Accepts payment on Base or Solana — either network works.

## Output

Returns a JSON object with the source currency (USD), target currency (JPY), live exchange rate, the input amount, the converted result in JPY, the rate timestamp (as_of), and the data source.
