Calculates gross spread in bps, pool fee-adjusted net arbitrage profitability, optimal routing direction (BUY_AERODROME_SELL_UNISWAP or reverse), and estimated net profit per $1,000 USD. Essential for trading agents and market makers. Pass token= (token contract address).
Output

Technical details
Endpoint
GEThttps://402.com.tr/api/x402/base-dex-spread?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, fee-adjusted arbitrage profitability between Aerodrome and Uniswap v3 specifically on the Base chain. It is ideal for autonomous trading agents, market makers, and routing engines that need to know not just the raw price difference but the direction and net profitability after pool fees, expressed per $1,000 USD. Prefer this over generic price feeds when you need actionable routing direction rather than just a spot price.
Side effects

- Token not listed on one or both DEXes results in incomplete comparison
- Insufficient liquidity in a pool may yield unreliable spread estimates
- Network or RPC latency on Base may cause stale or failed data fetch
- Malformed token address format causes a validation error
