agent402.tools/api/perp-funding

Current and historical funding rate for one perpetual futures market, from a live derivatives venue: hourly rate, the 8-hour and annualized equivalents, the mark-vs-oracle premium, and a window of past prints with average, minimum, maximum and the share that were positive. Use it when an agent needs to know what holding a leveraged position costs right now, or wants to detect a funding regime flip before sizing a trade.
