How this service works
86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.
Output
Returns a JSON object with per-coin, per-venue data including funding rate (per interval), APR percentage, mark price, open interest in USD, next funding time, and interval hours. Also includes cross-venue summary fields: max APR venue, min APR venue, average APR, spread APR, total open interest, and a plain-English arbitrage hint suggesting which venue to short and which to go long on to capture the spread.
Example use cases
Funding arbitrage opportunity scanner
“Check the perpetual funding rates for BTC and SOL across Binance, Bybit, OKX, and Hyperliquid and tell me if there's a worthwhile arbitrage spread I can capture by going long on one exchange and short on another.”
DeFi yield comparison for perp traders
“What's the current annualized funding rate APR for ETH and HYPE on Hyperliquid and Bybit? I want to know which venue is paying the most to shorts right now.”
Open interest and market sentiment check
“Pull the open interest and funding rates for BTC on all four venues — Binance, Bybit, OKX, and Hyperliquid — so I can get a sense of where the market is positioned and how much longs are paying shorts.”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/perp-funding?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time cross-venue perpetual futures funding rate data with built-in arbitrage analysis. It covers four major venues (Binance, Bybit, OKX, Hyperliquid) in a single call and provides computed APR, open interest, and actionable arbitrage hints — saving you from querying each exchange separately and doing the math yourself. Prefer it over exchange-specific APIs when you need a unified, multi-venue comparison in one request.
Side effects
- Invalid or unsupported coin ticker returns no data for that coin
- Unsupported venue enum value causes validation error
- Exchange API outage may result in missing venue data for some coins
- Requesting more than 10 coins at once is rejected
- Payment failure via x402 results in 402 response and no data returned
