How this service works
Ranked cross-DEX arbitrage spreads across every liquid pair on BSC / BNB Chain (PancakeSwap v2/v3, Biswap, ApeSwap). Returns opportunities[] with pair, grossSpreadBps, buyAt, sellAt, optimalTradeSizeUsd, capturable. GROSS, before gas and MEV. Optional ?minSpreadBps=20 (default 10), minVenueTvlUsd, limit. Send one param: a bare call skips the free tier. Errors: 400 bad_min_spread. Scans EVERY pair; for one known pair use /route. Bare = BSC; also /polygon /arbitrum /avalanche /optimism /base.
Output
A ranked list of cross-venue arbitrage opportunities on BNB Chain, each entry containing: the token pair, the DEX to buy on, the DEX to sell on, the gross spread in basis points, the optimal trade size, and the gross USD profit at that size. Venues below the specified liquidity floor are excluded. All figures are gross before gas costs and MEV.
Example use cases
Arbitrage bot opportunity feed
“Scan BSC DEXs right now and give me all cross-venue arbitrage spreads above 15 basis points — I need the buy venue, sell venue, spread size, and optimal trade size so my bot can evaluate which ones to execute.”
Manual DeFi trader scouting
“What are the top 10 arbitrage opportunities on BNB Chain across PancakeSwap and Biswap right now? Show me anything with at least 25 bps spread and filter out any pools with less than $10,000 in liquidity.”
DEX spread monitoring for risk desk
“Pull the current cross-DEX spreads on BSC with a minimum of 10 basis points and no venue TVL floor — I want to see how wide spreads are getting across PancakeSwap v2, v3, Biswap, and ApeSwap to gauge market efficiency.”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/scanWhen to prefer
Use this endpoint when you need a real-time, multi-venue arbitrage scan across BNB Chain's major DEXs in a single call. It is preferable to per-venue price queries when you want ranked spreads across PancakeSwap v2, v3, Biswap, and ApeSwap simultaneously, and when you want liquidity-filtered results that exclude dust pools automatically.
Side effects
- No opportunities found if minSpreadBps is set too high relative to current market conditions
- All venues excluded if minVenueTvlUsd floor is set too high
- Stale or incomplete data if on-chain RPC is lagging
- Invalid minSpreadBps value type returns a 400 error
- Network congestion on BSC may cause delayed or failed on-chain reads
