## 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 money-reactor-cross-asset-converter-ab4309c5
```

Example prompt: How much ETH would I get for 2.5 BTC right now? Use the live Coinbase spot rate to convert and give me the rate too.

## When to prefer this

Choose this endpoint when you need a quick, single-call cross-asset conversion with a live Coinbase spot rate and don't want to separately fetch prices and do the math. It's ideal for real-time trade estimation, portfolio calculations, or any scenario requiring the converted amount and rate together in one response. Prefer it over a batch price endpoint when you only need one specific pair and want the calculation done server-side.

## Known failure modes

- Unsupported or invalid asset code returns an error (e.g. typo in ticker symbol)
- Amount of 0 or negative values may produce unexpected results
- Rate temporarily unavailable if Coinbase spot feed is down
- Missing required query parameters (from, to, or amount) return a bad request error
