How this service works
Greedy multi-venue execution route for one crypto perpetual: walks venues in slippage order, allocating up to each venue's depth cap until size_usd is filled. Returns the route, total filled and blended slippage — how a large order splits across CEX and DEX venues. NAIVE: excludes fees.
Output
Returns a ranked execution route showing which venues are used, how much USD is allocated to each (up to per-venue depth caps), total filled amount, and a blended slippage figure across all venues. Note: fees are not included in the slippage calculation.
Example use cases
Example prompt
“I need to fill $75,000 worth of ETH-PERP using the greedy multi-venue route — walk venues in slippage order and tell me the full execution route, how much gets filled, and the blended slippage across all venues.”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/orderbook/multi-venue-executionWhen to prefer
Use this endpoint when you need to optimally route a large notional crypto order across multiple venues to minimize blended slippage. Prefer this over the single-venue best execution endpoint when your order size exceeds a single venue's depth or when you want to compare multi-venue vs single-venue execution quality. Best for pre-trade analysis rather than live execution, and when fee-exclusive slippage estimates are sufficient.
Side effects
- Requested size_usd too large for available cross-venue depth — partial fill returned
- Unknown or unsupported ticker symbol — 400 error
- Per-venue depth caps too restrictive to fill full size — partial route returned
- No venues available for the given symbol at query time
- Payment failure or missing x402 payment header — 402 error
