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
A JSON object keyed by coin symbol (e.g. BTC, ETH) containing: mark price, oracle price, open interest (in contracts and USD), hourly funding rate, annualized funding rate as a percentage, the venue name ('hyperliquid'), upstream data source URLs, and an updated_at timestamp.
Example use cases
Funding arbitrage signal for trading bot
“Pull the current Hyperliquid funding rates for BTC and ETH — I need the hourly rate and annualized APR so my bot can decide whether to go long or short the funding.”
Open interest spike monitoring
“Check Hyperliquid right now and tell me which coins have unusually high open interest in USD — I want to spot any big buildup in BTC or ETH perps.”
Mark vs oracle price divergence check
“What's the current mark price versus oracle price for BTC on Hyperliquid? I'm trying to see if there's a significant spread before my agent places a trade.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/funding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs real-time Hyperliquid perpetual funding rates and open interest without managing API keys — ideal for autonomous trading agents that already handle x402 USDC micropayments on Base. Prefer it over direct Hyperliquid API calls when you want a pay-per-call model with no authentication setup, or when combining with other crypto microdata endpoints (gas, prices, kimchi premium) from the same provider in a single agent workflow.
Side effects
- Payment not attached or invalid USDC micropayment returns HTTP 402
- Hyperliquid upstream API unavailable causes stale or missing data
- Unsupported coin symbol returns empty coins object
- Network timeout from Cloudflare Worker if Hyperliquid API is slow
- Malformed request may return 400 bad request
