How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
Returns a JSON object with the coin symbol, venue (e.g. Hyperliquid), as_of timestamp, count of records, and a history array where each entry contains: time (ISO timestamp), funding_rate_hourly (fractional rate), funding_apr_percent (annualized rate), and premium (basis). Covers up to 720 hours of history.
Example use cases
Spot carry trade opportunities in crypto
“Check the funding rate history for ETH perps on Hyperliquid over the last 7 days — I want to know if the funding APR has been consistently positive and whether there's a viable carry trade opportunity right now.”
Monitor BTC funding regime shifts
“Pull the last 30 days of BTC perpetual funding data from Hyperliquid and flag any points where the funding rate flipped from positive to negative — I'm trying to spot regime changes and understand how long each lasted.”
Backtest SOL perp funding strategy
“Get me up to 720 hours of SOL perpetual funding rate history from Hyperliquid, including the hourly rate, annualized APR, and premium for each entry — I need this to backtest a funding-rate mean-reversion strategy.”
