## 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-smart-money-data-api-market-data-by-asset-class-0a1a8932
```

Example prompt: Show me the current mark price, funding rate, and open interest for all crypto markets on Hyperliquid — I don't need the other asset classes, just crypto.

## When to prefer this

Choose this endpoint when you want a focused snapshot of one asset class (e.g. only crypto or only FX) rather than all 320 Hyperliquid markets at once. It is more efficient than the full-market endpoint when your downstream logic only concerns one category, and cheaper to parse and act on. Prefer it over the AI narrative or squeeze-screen endpoints when you need raw numeric data (mark price, funding, OI) for your own analysis rather than pre-interpreted signals.

## Known failure modes

- Invalid asset_class path parameter returns an error or empty result
- Network or payment failure (402) if x402 micropayment is not handled
- Rate limiting if called too frequently
- Empty result set if no markets exist for the requested asset class at that moment

## How this service works

Screen one asset class without pulling all 320 markets: mark price, funding rate and open interest for crypto, equities, commodities, FX, indices or rates

## Output

A filtered list of Hyperliquid markets belonging to the specified asset class, each with its current mark price, funding rate, and open interest — narrowed to one class so the response is compact and actionable without loading all 320 markets.
