How this service works
Cross-venue perpetual funding rates (OKX, Kraken Futures, dYdX) for any major token. Per-venue annualized rates plus the cross-venue spread in percentage points — a ready-to-use funding arbitrage signal. Clean JSON for trading and research agents.
Output
A JSON object containing the token symbol, a UTC timestamp for the data snapshot, a list of venues each with their raw funding rate, annualized percentage rate, and interval hours, plus a cross-venue annualized spread in percentage points that serves as an arbitrage signal.
Example use cases
Funding rate arbitrage scanner
“Check the cross-venue perpetual funding rates for BTC right now and tell me if the annualized spread between venues is wide enough to be worth arbitraging.”
Automated trading strategy input
“Pull the latest perpetual funding rates for SOL across all available exchanges so my strategy can decide whether to go long or short the funding.”
DeFi market condition monitor
“What are the annualized perpetual funding rates for ETH on each venue right now, and flag if any single venue looks like an outlier compared to the others?”

Endpoint
GEThttps://defi-signals.org/defi/funding-ratesWhen to prefer
Choose this endpoint when you need real-time, cross-venue perpetual futures funding rates with a pre-computed arbitrage spread signal, especially if you are running an AI agent that needs to make funding-rate-aware trading decisions or monitor arb opportunities without building your own aggregation layer. It is priced per call at $0.005 USDC via x402, making it cost-effective for on-demand queries rather than continuous streaming.
Side effects
- Unsupported or misspelled token symbol returns empty venues array or error
- Payment failure (insufficient USDC or x402 handshake failure) blocks access
- Stale data if upstream venue APIs are temporarily unavailable
- Rate or quota limits may apply if too many calls are made rapidly
- Network timeout if the endpoint is slow to aggregate cross-venue data
