## 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-b5c91c5d
```

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 in one shot.

## When to prefer this

Choose this endpoint when you need comprehensive perpetual futures data — especially funding rates and open interest — that is unavailable from spot market feeds. Ideal for derivatives traders, arbitrage monitors, and risk dashboards requiring live Hyperliquid perp state across all coins in a single call. Prefer over spot feeds when funding rate or leverage data is required, and over exchange-specific APIs when you want aggregated perp market state without managing exchange credentials.

## Known failure modes

- Hyperliquid API unavailability causes empty or stale data
- Rate limiting or upstream timeout returns 5xx error
- Payment of 0.02 USDC not processed results in 402 Payment Required
- Individual coin fields may be null if data is temporarily unavailable for that market
- Schema validation failure if upstream data format changes

## 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 object containing a timestamped snapshot of all perpetual futures markets on Hyperliquid, with per-coin fields including: coin ticker, mark price, oracle price, mid price, previous day close, hourly funding rate, annualized funding APR (%), premium, open interest, max leverage, 24h volume in USD, and 24h volume in base currency. Also includes top-level metadata: source, venue, market type, timestamp, and total market count.
