## 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 twelvex-crypto-quote-via-twelve-data-6b3b2196 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need real-time or latest cryptocurrency quote data for a specific symbol and are operating in a pay-per-call x402 micropayment context. Prefer this over free-tier alternatives when reliability and freshness of Twelve Data's feed is required, or when integrating into an autonomous agent pipeline that handles USDC micropayments natively.

## Known failure modes

- Invalid or unsupported crypto symbol returns an error or empty result
- Rate limiting or payment failure (402) if USDC micropayment is not processed
- Symbol format mismatch (e.g. missing pair like BTC vs BTC/USD) causes lookup failure
- Downstream Twelve Data API unavailability results in timeout or 503
- Malformed POST body causes 400 bad request
