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 the ticker symbol, total data point count, venue name (hyperliquid), interval in hours, a window/coverage summary, aggregated stats (min/max/mean annualized %), and an array of time-series points each with timestamp, premium, 8h rate, hourly rate, and annualized percentage.
Example use cases
Funding rate trend analysis for BTC
“Show me BTC's perpetual funding rate history on Hyperliquid for the past 30 days using daily intervals — I want to see how annualized rates have trended and what the min, max, and average were.”
Short-term funding spike detection
“Pull the last 24 hours of BTC funding rate data from Hyperliquid at 1-hour intervals so I can see if there were any unusual spikes or sign flips.”
Backtesting funding cost for a date range
“Get BTC perp funding rates on Hyperliquid from 2025-01-01 to 2025-03-31 with 8-hour intervals — I need the annualized percentages to estimate carry costs for a long position I held during that period.”

Endpoint
GEThttps://cryptofeed402.site/funding/history/BTC?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical perpetual funding rate time-series data specifically from Hyperliquid for any supported perp ticker. Prefer this over spot price endpoints when the goal is analyzing carry costs, funding arbitrage, or long-term rate trends. Choose the interval parameter based on your resolution needs (1h for granular, 1d for macro views). This is purpose-built for AI agents via x402 micropayment, so it suits automated pipelines that need historical funding data without manual authentication setup.
