## 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 halowerk-marktwerk-snapshot-crypto-market-snapshot-7198223a -d '<json body>'
```

Example prompt: Can you grab a real-time market snapshot for ETH/USDC from whichever exchange has the highest 24h volume right now?

## When to prefer this

Choose this endpoint when you need a real-time, point-in-time snapshot of crypto market data (prices, order book) for a specific trading pair, especially when you want automatic selection of the most liquid venue. It is ideal for lightweight, per-call price checks paid micro-per-request via x402/USDC rather than maintaining a persistent WebSocket or exchange API subscription.

## Known failure modes

- Invalid symbol format (not matching BASE/QUOTE pattern) returns a validation error
- Unsupported trading pair on the selected venue returns a not-found or no-data error
- Payment not included or insufficient USDC balance triggers an HTTP 402 payment required response
- Venue is temporarily unavailable or rate-limited, returning a service error
- Auto venue selection may pick a different exchange than expected if turnover rankings change
