How this service works
Real-time multi-DEX aggregated crypto market data. Pay per request with USDC on Base via x402 protocol.

Example use cases
Pre-trade funding rate check
“Before I open a long position on ETH perps, can you check the current funding rate and what the predicted next rate looks like — I want to know if the trend is working against me?”
Funding rate arbitrage signal
“Pull the current and predicted funding rates for SOL perpetual futures so I can evaluate whether a funding rate arbitrage play makes sense right now.”
Automated trading strategy input
“Get me the predicted next funding rate and trend direction for BTC-PERP — I need it to decide whether to hold my short position overnight.”
Technical details
Endpoint
GEThttps://api.foursec.xyz/futures/predicted-funding/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need forward-looking funding rate intelligence for crypto perpetual futures, specifically the AI-predicted next funding rate combined with trend direction — not just the raw current rate. It is ideal for pre-trade decision support, funding arbitrage screening, or automated trading strategies that require a signal on whether rates are rising or falling. Prefer this over generic market data feeds when the predicted next rate and trend label are specifically required.
