## 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 x402stock-perpetual-futures-market-data-fe8ecf29
```

Example prompt: Pull the live snapshot of all perpetual futures markets on Hyperliquid — I want to see funding rates, open interest, mark and oracle prices, and 24h volume for every coin right now.

## When to prefer this

Use this endpoint when you need comprehensive perpetual futures data — funding rates, open interest, and leverage — that is absent from spot market feeds. Ideal for DeFi trading strategies, funding rate arbitrage research, or monitoring all Hyperliquid perp markets in a single call without an API key. Prefer over spot feeds when derivatives-specific metrics are required.

## Known failure modes

- Payment required (402) if x402 payment header not included
- Upstream Hyperliquid DEX data unavailable causing stale or missing data
- Rate limiting if called too frequently
- Null values for some per-coin fields if market data is temporarily unavailable

## How this service works

Live state of every perpetual-futures market in one call: per coin the mark and oracle price, hourly funding rate with annualized APR, premium, open interest, max leverage, previous-day price, and 24h USD and base volume. Native crypto-derivatives data — funding and open interest are perp-only, absent from any spot feed. Free on-chain DEX data (venue: Hyperliquid), no key. From x402stock

## Output

A JSON array of all perpetual futures markets on Hyperliquid, each entry containing: coin symbol, mark price, oracle price, mid price, previous day price, hourly funding rate, annualized funding APR, premium, open interest, max leverage, 24h USD volume, and 24h base volume. Also includes metadata: source, venue, timestamp, market type, and total count.
