How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
Returns a JSON object with mark price, oracle price, open interest (raw and USD-denominated), hourly funding rate, annualized funding rate as a percentage, the venue name (hyperliquid), data sources, and an updated_at timestamp. All data is sourced live from Hyperliquid's public info API.
Example use cases
Carry trade direction decision
“Check the Hyperliquid funding rate for ETH perps — is the annualized APR high enough that it's worth being short to collect funding, and how much open interest is there?”
BTC perp mark vs oracle divergence check
“What's the difference between the mark price and oracle price for BTC on Hyperliquid right now, and what's the current funding rate?”
SOL perpetuals funding monitoring
“Pull the latest Hyperliquid funding data for SOL perps — I want the hourly funding rate and total open interest in USD so I can decide whether to enter a position.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/hyperliquid/funding?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI trading agent needs real-time Hyperliquid-specific perpetuals data — particularly funding rates and open interest — without setting up API keys. Ideal for pay-per-call agent architectures using x402 micropayments on Base. Prefer this over generic crypto APIs when Hyperliquid-specific mark/oracle price divergence or funding APR is specifically needed for carry trade analysis or position sizing decisions.
Side effects
- Invalid or unsupported coin symbol returns an error (only BTC, ETH, SOL supported)
- Payment failure via x402 if USDC balance on Base is insufficient
- Hyperliquid upstream API unavailability causes stale or missing data
- Network timeout on the Cloudflare Worker edge function
- Missing coin query param defaults to BTC silently — may confuse agents expecting explicit validation
