How this service works
Per-venue slippage scan for one crypto perpetual at $1K/$5K/$10K notional, across tracked CEX and DEX venues — every venue sorted by lowest slippage, with BBO and depth. Raw scan, no opinionated ranking: where a given size is cheapest to execute.
Output
A list of all supported venues sorted by lowest slippage for the requested ticker, each entry containing slippage estimates at $1K/$5K/$10K notional, best bid/ask prices, and order book depth data. No fees or funding adjustments are applied — raw execution cost only.
Example use cases
Find cheapest venue for medium order
“I want to execute a $5K trade on SOL. Can you scan all venues and tell me which one gives me the best execution price with the lowest slippage?”
Compare order book depth across exchanges
“Show me the order book depth and best bid-ask spreads for ETH across all supported venues so I can see which exchange has the most liquidity.”
Route large trade to minimize impact
“I'm planning to buy $10K of AVAX. Scan all the venues and rank them by slippage at that size so I can route to the exchange with the least market impact.”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/orderbook/multi-venue-slippageWhen to prefer
Use this endpoint when you need a broad cross-venue comparison of execution quality at multiple notional sizes in a single call. Prefer this over the single-venue slippage endpoint when you don't know which venue to use and want to discover the optimal routing venue. Use the greedy multi-venue router instead if you need to actually split and execute a large order across venues.
Side effects
- Unknown or unsupported ticker symbol returns empty venue list or 404
- Stale order book data may produce inaccurate slippage estimates during low-liquidity periods
- Rate limiting or payment failure (402) if USDC payment not included
- Partial results if some venues are temporarily unavailable during the scan
