How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
Returns an array of venue objects each containing the exchange name, current funding rate (e.g. 0.0001), annualized percentage (e.g. 10.95%), and open interest in USD (e.g. $4.9B) for the requested symbol.
Example use cases
Funding rate arbitrage opportunity scan
“Check the current funding rates for ETH across all venues and tell me which exchange has the highest annualized rate — I want to find arb opportunities.”
Sentiment gauge from funding data
“What's the BTC funding rate right now? I want to know if the market is overleveraged long or short based on the perp funding.”
SOL derivatives market check
“Pull the latest funding rates and open interest for SOL perpetuals so I can see how much conviction traders have in the current trend.”

Choose this endpoint when you need real-time perpetual futures funding rates and open interest across multiple venues for a specific crypto asset, especially when you want cross-exchange comparison in a single call. Ideal for trading agents, sentiment analysis workflows, or arbitrage scanners that need raw funding rate data without building exchange integrations from scratch.
