How this service works
AI-to-AI crypto data. Paid routes use x402 (USDC on Base mainnet eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913); unpaid calls return 402 with payment requirements. Not financial advice.
Output
A JSON object containing: current timestamp and venue (Hyperliquid), ETH mark price, oracle price, premium and premium percentage, bid/ask impact prices, funding rate (hourly and 8h), annualized funding APR, which side is paying (longs or shorts), funding interval, open interest in USD and ETH coins, 24h volume in USD, 24h price change percentage, max leverage, and a funding extremity rank showing where ETH sits relative to other assets in the universe.
Example use cases
Funding rate arbitrage monitoring
“Check the current ETH perp funding rate on Hyperliquid — is it positive or negative, and what's the annualized percentage? I want to know if shorts or longs are paying.”
Pre-trade leverage and liquidity check
“Before I open a position, give me the ETH perp snapshot from Hyperliquid — I need the mark price, oracle price, max leverage, and the bid/ask impact prices.”
Extreme funding alert for ETH
“Is ETH currently in the top 10 for extreme funding rates across Hyperliquid? Show me its funding rank and annualized rate so I can decide if it's worth fading.”

Endpoint
GEThttps://cryptofeed402.site/perps/ETH?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, all-in-one ETH perpetuals data snapshot from Hyperliquid specifically, covering mark price, funding rate, open interest, volume, leverage, oracle price, and funding extremity ranking in a single call. It is optimized for AI-to-AI consumption via x402 micropayments and is ideal when you want structured, machine-readable perp data without scraping or managing a WebSocket connection. Prefer this over generic crypto price APIs when funding rate, open interest, and leverage metadata are required together.
Side effects
- 402 Payment Required — no valid x402 USDC payment header on Base mainnet provided
- Invalid or unsupported symbol in path (only BTC, ETH, SOL, HYPE, NEAR, AAVE supported)
- Upstream Hyperliquid data unavailable — stale or missing snapshot
- Network timeout if Hyperliquid API is slow or down
- Malformed payment — wrong chain, wrong asset address, or insufficient amount
