How this service works
Live, cost-aware cross-venue perpetual-funding screens for trading agents. x402 payment; no API key or account.
Output
Returns a ranked list of top cross-venue carry spread opportunities, each with the long venue, short venue, coin, gross annualized spread, projected net yield percent, projected net funding in USD, assumed total cost, break-even hours, execution tier, and cost screen status — plus the assumptions used and a liquidity floor summary showing screened market count and Hyperliquid volume/OI figures.
Example use cases
Weekly carry trade opportunity scan
“I want to put on a $50,000 cross-venue perp carry trade for about a week — assume 15 bps in total fees and slippage. What are the best long-short funding spread opportunities right now sorted by net annualized return?”
Intraday funding arb with tight cost budget
“Screen perpetual futures carry spreads for a $5,000 notional held for just 8 hours, with only 10 bps of total costs — which pairs break even the fastest and have the highest projected net yield?”
Large-notional institutional carry screening
“I'm sizing a $500,000 cross-venue perp funding trade with a 30-day holding period and 25 bps all-in costs. Pull the top carry spreads and tell me which coins pass the cost screen and hit the high execution tier.”
Technical details
Endpoint
GEThttps://carry-lens-api.netlify.app/v1/perps/radarWhen to prefer
Choose this endpoint when you need a live, cost-adjusted ranking of cross-venue perpetual funding carry spreads across multiple crypto exchanges in a single call — especially when you want break-even analysis and net yield projections already computed for a given notional, holding period, and cost budget, without needing to aggregate and normalize raw funding rate feeds yourself. Prefer it over raw exchange APIs when you need ready-to-act carry trade signals with execution-tier classification.
Side effects
- Invalid notionalUsd format (non-numeric string) returns a 400 validation error
- holdingHours outside the 1–2160 range may return empty or erroneous results
- totalCostBps above 2000 may filter out all opportunities, returning an empty spreads array
- Payment failure via x402 protocol results in a 402 response and no data returned
- Stale funding data if upstream venue feeds are delayed may produce inaccurate spread projections
- Network timeout to Netlify-hosted endpoint possible under high load
