How this service works
Paid market-intelligence API over x402
Output
A JSON object with the asset's cross-venue perpetual futures funding rates including: best long and short venues with their 8-hour rates, gross and net spread in basis points, annualized yield percentage, open interest per venue, simple and OI-weighted rate averages, dispersion statistics (stdev, max-min spread), per-venue breakdown (rate, OI, funding interval), an actionability flag, methodology explanation, and caveats about execution costs and rate volatility.
Example use cases
Funding arb opportunity scanner
“Check BTC-USD funding rates across all venues right now and tell me which exchange to go long on and which to go short on for a funding arb, and whether the net spread after fees is worth executing.”
Daily crypto derivatives briefing
“Give me a breakdown of today's ETH-USD funding rate arb signals — I want the annualized yield, the dispersion across venues, and whether it's currently actionable.”
Algo strategy pre-trade check
“Before I open a SOL-USD funding arbitrage position, pull the latest cross-venue funding rates, show me the gross and net spread in bps, and flag if the trade is actionable.”
Technical details
Endpoint
GEThttps://kronossignals.com/api/v1/funding-arb/%7Basset%7DWhen to prefer
Use this endpoint when you need structured, multi-venue funding rate arbitrage intelligence for a specific crypto perpetual futures asset, with pre-computed spread, annualized yield, and actionability assessment. Prefer it over raw exchange APIs when you want normalized cross-venue comparison with fee modeling already applied. It is specifically designed for funding arb workflows, not general price or sentiment queries.
Side effects
- Invalid or unsupported asset symbol returns an error or empty response
- Payment failure via x402 protocol blocks access to data
- Stale or missing data from one or more venues reduces venues_count
- Net spread may be negative (not_actionable) even when data is returned successfully
- Rate limits or upstream exchange API outages may cause partial venue coverage
