Output
A JSON object containing the caller's assumptions (notional, holding hours, cost bps) and an array of the top 3 cross-venue perpetual funding carry spread opportunities, each with the venue pair, gross funding dollars, projected net funding after supplied costs, break-even time in hours, liquidity tier classification, and BTC/ETH/SOL funding rate context.
Example use cases
Example prompt
“Pull the top cross-venue perp carry spreads for a $25,000 notional position held for 48 hours with 8 bps all-in costs so I can see the projected net funding and break-even time for each opportunity.”
Technical details
Endpoint
GEThttps://carry-lens-api.netlify.app/v1/perps/pulseWhen to prefer
Use this endpoint when a trading agent needs real-time, cost-adjusted ranking of cross-venue perpetual funding carry trades — specifically when the agent has a known notional size, holding period, and all-in fee estimate and wants to identify the top actionable spread opportunities with break-even analysis rather than raw funding rate data.
