## 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 whaletape-hyperliquid-smart-money-markets-by-asset-class-0883589d
```

Example prompt: Pull the latest open interest, funding rates, and 24h volume for all crypto markets on Hyperliquid — I want to see which ones have unusual whale positioning right now.

## When to prefer this

Use this endpoint when you need a broad, cross-market snapshot of OI, funding, and volume for an entire asset class on Hyperliquid in one call, rather than querying a single instrument or needing historical time-series data. It is ideal for scanning all markets simultaneously to detect anomalies, rather than tracking one asset over time.

## Known failure modes

- Invalid or unsupported asset_class value returns empty or error response
- Payment not fulfilled (x402) results in 402 Payment Required before data is served
- Stale data if Hyperliquid feed is temporarily delayed
- Rate limiting if payment is not provided per-request

## How this service works

## Output

A JSON object containing a count of markets, an updated_at timestamp, the queried asset_class, and an array of market objects each with coin, symbol, DEX, funding rate, mark price, 24-hour volume, asset class, and open interest figures — all sourced live from Hyperliquid.
