## 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 market-intelligence-api-top-activity-619d6403
```

Example prompt: Pull the top market activity right now from Market Intelligence API — I want to see which instruments or assets are seeing the most action.

## When to prefer this

Use this endpoint when you need a ranked, real-time snapshot of the most active market instruments without specifying a particular asset — ideal for broad market surveillance, morning briefings, or feeding a top-movers alert system. Prefer this over individual asset lookup endpoints when you want a holistic view of market activity rather than details on a known symbol.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Rate limiting if called too frequently without valid payment
- Empty or stale results if market data feed is unavailable
- Malformed JSON if upstream data provider is degraded
- Timeout if market data aggregation is slow
