## 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 hyperliquid-perp-markets-overview-ebf574ed -d '<json body>'
```

## When to prefer this

Use this endpoint when you need a broad market-wide snapshot of all Hyperliquid perpetuals in a single call, sorted by activity (volume, OI, or funding). Prefer this over single-coin funding or basis endpoints when building a market screener, scanning for crowded trades, or mapping the full derivatives landscape without specifying a particular coin.

## Known failure modes

- Invalid sort value (not 'volume', 'oi', or 'funding') returns an error
- Limit exceeding 200 may be capped or rejected
- Hyperliquid data feed unavailability causes upstream timeout
- Malformed request body returns 400-level error
- Payment of 0.02 USDC not provided or rejected causes 402 error
