How this service works
Cross-DEX Arbitrage & Liquidity Scanner. Analyzes Uniswap, Aerodrome, and BaseSwap pools for profitable routing opportunities.
Output
Returns a comparison of pool prices and liquidity across Uniswap, Aerodrome, and BaseSwap for the specified token pair, highlighting any routing opportunities where the spread meets or exceeds the specified minimum basis points threshold. Likely includes per-DEX price quotes, spread calculations, and suggested arbitrage direction.
Example use cases
Automated arbitrage bot signal sourcing
“Check for arbitrage opportunities on WETH/USDC across Uniswap, Aerodrome, and BaseSwap — flag anything with a spread above 50 basis points so my bot knows when to execute a trade.”
Manual trader cross-DEX spread check
“Is there a profitable price difference right now for USDC/cbBTC across any of the major Base DEXes? I want to see spreads of at least 20 basis points.”
DeFi strategy research for new token pair
“I'm researching whether BRETT/WETH is worth arbitraging on Base — can you scan Uniswap, Aerodrome, and BaseSwap and show me the current spread landscape, filtering for anything above 40 bps?”
Technical details
Endpoint
POSThttps://x402-agent-tollbooth.onrender.com/toll/arbitrage_scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-DEX arbitrage scan specifically across Uniswap, Aerodrome, and BaseSwap on the Base chain. It is ideal for DeFi agents or bots that need real-time spread detection across these three protocols without building their own pool-querying infrastructure. Prefer it over generic price feeds when you need cross-DEX comparison with spread filtering by basis points.
Side effects
- Invalid or unsupported token pair returns an error or empty result
- min_spread_bps set too high may return no opportunities even when spreads exist
- Pool data may be stale if underlying DEX APIs are lagging
- Network or RPC issues on Base chain could cause fetch failures
- Payment failure via x402 protocol prevents the call from completing
