## 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 basebuilder-crypto-coin-data-a52c857d -d '<json body>'
```

Example prompt: What's the current price, market cap, and 24-hour price change for Bitcoin right now?

## When to prefer this

Use this endpoint when you need real-time or near-real-time market data for a specific cryptocurrency coin — especially price, market cap, and volume — and are operating within a micropayment (x402) context where per-call billing via USDC is acceptable. Prefer this over free alternatives when reliability and structured output are needed for agent workflows.

## Known failure modes

- Malformed request body returns 400 bad request
- Payment not provided or insufficient returns 402 Payment Required
