How this service works
Paid funding rate decision API for AI trading agents across up to 16 perp venues. Settled via x402 on Base mainnet (eip155:8453) using the Coinbase Mogami v2 facilitator; unpaid requests receive a 402 challenge that lists the per-route price.
Output
Returns an array of arbitrage opportunities, each with the symbol, annualized spread, per-venue funding rate records (rate, interval, next funding time, cadence type), a recommendation object listing which venue to go long and which to go short, a confidence level (high/medium/low), and any applicable warnings such as stale data or interval mismatches. Also includes top-level meta and warnings fields.
Example use cases
Monitor SOL perps funding arbitrage
“Find me the best funding rate arbitrage opportunities for SOL across all available venues right now, and let me know which exchange I should long and which I should short for each opportunity.”
High-confidence cross-venue arb signals
“Show me any funding rate arbitrage opportunities across crypto perp exchanges that have a high confidence rating and at least a 7% annualized spread that I could execute today.”
Real-time funding spread tracking
“What's the current funding rate spread between Binance and Hyperliquid for major coins like BTC, ETH, and XRP? Give me the ones with the biggest differences right now.”
Technical details
Endpoint
GEThttps://funding-rates-x402.data-labs.cloud/v1/funding/arbitrageWhen to prefer
Use this endpoint when an AI trading agent needs a ready-made, actionable cross-venue funding rate arbitrage signal with leg recommendations rather than raw funding rate data it must analyze itself. Prefer this over raw data feeds when you want confidence scoring, filtering by minimum spread, and multi-venue normalization (including both periodic and continuous accrual venues like Reya and Paradex) in a single call.
Side effects
- 402 Payment Required — no valid MPP payment receipt provided; response includes per-route pricing challenge
- No opportunities returned if minAnnualizedSpread threshold is too high or no spread exists at query time
- 'source_stale' or 'source_refresh_failed' warnings if venue data is outdated
- 'insufficient_venues' warning if fewer than 2 venues return data for a symbol
- 'unsupported_symbol' or 'unsupported_venue' warning for unrecognized inputs
- 'interval_mismatch' warning when comparing venues with different funding cadences
- 'fees_not_included' warning reminding that trading fees are not factored into spread calculations
