How this service works
Builds on cross-venue funding with size-aware fields: Jupiter Quote spot slippage at requested size, per-venue fee, OI cap headroom, first-hour borrow cost, and total entry cost. Returns rankings by entry cost / borrow APR / headroom plus a recommendation venue with warnings. Use when sizing a real position; use perps-cross-venue-funding for rates-only context.
Output
A structured breakdown per venue showing: Jupiter Quote spot slippage at the requested size, per-venue fee, open interest cap headroom, first-hour borrow cost, and total entry cost. Also includes venue rankings by entry cost, borrow APR, and OI headroom, plus a recommended venue with any relevant warnings.
Example use cases
Example prompt
“I want to open a $75,000 SOL long — can you compare Solana perp venues by total entry cost, including slippage, fees, OI headroom, and first-hour borrow cost, and tell me which venue you recommend?”
Technical details
Endpoint
POSThttps://api.solenrich.com/entrypoints/perps-venue-comparison/invoke?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to size a real position and want a full cost breakdown including slippage, fees, and borrow costs across venues — not just funding rates. Prefer this over perps-cross-venue-funding when the user has a specific dollar size in mind and needs a venue recommendation. It is particularly valuable for large trades where slippage and OI headroom become material.

- Position size below $100 or above $10M returns out-of-range error

- Network timeout if on-chain data feeds are slow
