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 cross-venue perpetual funding carry spreads with projected economics (gross funding USD, net annualized %, breakeven hours, net yield %, net funding USD, assumed costs), plus a market regime label and stress score, risk flags, and Hyperliquid 24h funding persistence data — all computed against the supplied notional, holding period, and cost assumptions.
Example use cases
Delta-neutral carry trade screening
“Screen all perp pairs for cross-venue funding carry opportunities on a $50,000 notional, 72-hour hold, with 15 bps total costs — rank them by net annualized yield so I can pick the best delta-neutral trade.”
Break-even timing for short hold
“I'm planning to hold a cross-venue perp carry position for just 8 hours with $5,000 notional and 30 bps in costs — which coins will break even fast enough to be worth it?”
Market regime check before execution
“Before I put on any funding carry trades today, tell me the current market regime stress score and whether there are any systemic risk flags I should know about, using a $25,000 notional and 10 bps assumed costs.”
Technical details
Endpoint
GEThttps://carry-lens-api.netlify.app/v1/perps/report?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI trading agent needs live, cost-adjusted cross-venue perpetual funding rate comparisons ready for immediate trade sizing — especially when the agent needs projected net economics (not just raw rates), market regime context, and risk flags in a single call, without needing an API key or account. Prefer this over generic market data APIs when the goal is actionable carry trade screening with fee/slippage modeling built in.
Side effects
- Missing or malformed 'notionalUsd' pattern (must be numeric string 100–100000000) returns validation error
- 'holdingHours' out of range (must be 1–2160) causes rejection
- 'totalCostBps' exceeding 2000 is rejected
- Payment failure via x402 (insufficient USDC balance or missing payment header) blocks the response
- No carry spreads returned when funding rates are too compressed to pass cost screen
