How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns current funding rate data for perpetual futures markets across DeFi protocols — including rate values, direction (positive/negative), and potentially cross-exchange comparisons. Response is delivered as an HTTP HEAD response with payment settled via x402 USDC on Base at $0.005 per call.
Example use cases
Perp arbitrage opportunity scouting
“Show me the current funding rates across DeFi perpetual markets — I want to see which assets have the most extreme positive or negative rates so I can find carry trade opportunities.”
DeFi yield strategy optimization
“I'm running a delta-neutral DeFi strategy. Can you pull the latest funding rates across perpetual markets so I know where I'm earning or paying the most?”
Real-time funding rate alert check
“Check the current funding rates on crypto perps for me — I need to know if BTC or ETH funding has flipped negative in any major DeFi protocol.”
Technical details
Endpoint
HEADhttps://chat.sperax.io/api/x402/intel/funding-rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time DeFi funding rate intelligence without a long-term API subscription — ideal for pay-as-you-go agent workflows that make infrequent or bursty calls. Prefer this over traditional API-key services when operating with a crypto-native wallet agent on Base, or when building permissionless DeFi strategies that need up-to-date perpetual market rates without identity or KYC overhead.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or malformed x402 payment header — request rejected
- Network unavailability of Base chain for payment settlement — transaction fails
- Endpoint returns no body for HEAD requests — data may need to be retrieved via GET variant
- Stale or delayed funding rate data if upstream DeFi data sources lag
