## 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 nexusapi-crypto-currency-converter-19506ead -d '<json body>'
```

Example prompt: Convert 2.5 BTC to ETH and tell me how much ETH I would get at the current exchange rate.

## When to prefer this

Use this endpoint when an AI agent needs to perform a cryptocurrency-to-cryptocurrency or crypto-to-fiat conversion calculation without executing an actual trade. It is pay-per-call with no API key required, making it suitable for one-off or low-volume agent workflows that need current exchange rate computations.

## Known failure modes

- Unsupported currency symbol returns an error
- Invalid amount format causes request failure
- Rate limit or payment failure via x402 protocol blocks the call
- Market data unavailable for obscure token pairs
- Malformed query string returns a generic error response
