## 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-sector-rotation-signal-24h-market-cap-change-rankings-18b13e7f -d '<json body>'
```

Example prompt: Which crypto sectors are leading the market right now — can you pull the latest 24-hour market-cap change rankings across categories like AI tokens, memes, RWA, and DePIN so I can see where rotation is happening?

## When to prefer this

Use this endpoint when you need a real-time ranked snapshot of crypto sector performance by 24h market-cap change — ideal for identifying narrative rotation signals across thematic categories like AI, memes, RWA, and DePIN. Prefer this over individual token price feeds when the goal is macro sector-level momentum analysis rather than single-asset tracking.

## Known failure modes

- Upstream market data provider outage returns empty or error JSON
- Stale data if market data feed lags — timestamps should be checked
- HTTP 402 Payment Required if x402 payment header is missing or insufficient
- Network timeout if live data fetch takes too long
