## 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 xynaptic-crypto-live-cfe88a58
```

Example prompt: What are the live prices of Bitcoin, Ethereum, Solana, and Cardano right now — pull the actual real-time data, not a cached snapshot?

## When to prefer this

Choose this endpoint when you need the true real-time price of BTC, ETH, SOL, ADA or other top coins at the exact moment of the request — not a cached or periodically refreshed digest. Prefer this over the Xynaptic Crypto Brief (daily digest) when recency is critical, such as for trading decisions, live dashboards, or price alerts.

## Known failure modes

- Upstream exchange data unavailable — may return error or stale data
- Payment not processed — x402 payment required at $0.05 USDC per call
- Rate limiting if too many requests in quick succession
- Network timeout if underlying price feed is slow to respond
