Crypto Perp Snapshot ($0.02/call)
Crypto Perp Snapshot ($0.02/call): One-call perpetual-futures snapshot for a coin (BTC, ETH, SOL, ...): funding rate and open interest across Binance, Bybit and OKX, aggregate OI, average funding (annualized) with a longs-pay/shorts-pay read, mark price, next funding time and the Fear & Greed index. Keyless public exchange data; normalized so a trading agent gets one JSON instead of three exchange schemas.
