## 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 crypto-global-market-overview-e1fcd729 -d '<json body>'
```

Example prompt: What's the current total crypto market cap and how much is Bitcoin dominating the market right now? Include the 24-hour change too.

## When to prefer this

Use this endpoint when you need a quick, live snapshot of the entire crypto market — total cap, volume, and BTC/ETH dominance — without needing per-coin detail. Ideal for dashboards, market health checks, or dominance trend monitoring. Prefer over individual coin endpoints when aggregate market context is needed.

## Known failure modes

- Upstream data source unavailable — may return 5xx or stale data
- Rate limiting or payment failure (x402 payment required at $0.01 USDC per call)
- Network timeout if live data feed is slow to respond
