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-023b7143 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a quick, pay-per-call crypto-to-crypto conversion without managing API keys. Prefer it over self-hosted solutions when you want zero infrastructure overhead and real-time rates billed in USDC micro-payments via x402.
