How this service works
Pay-per-call (x402/USDC on Base) market-data, geocoding, randomness and hook-risk endpoints. Free demo route included.
Output
Returns the best buy venue (cheapest DEX), best sell venue (highest price DEX), cross-exchange spread expressed in basis points, fee-adjusted gross arbitrage spread, and an optimal trade size for the requested token pair on Base L2.
Example use cases
Pre-trade best execution check
“Before I swap 10 ETH worth of USDC on Base, check which DEX — BaseSwap, SushiSwap, or Uniswap v3 — gives me the best buy price for WETH/USDC and tell me the fee-adjusted spread.”
Base L2 arbitrage opportunity scanner
“Is there a meaningful arbitrage spread right now between DEXs on Base for the WETH/USDC pair? Give me the cross-exchange spread in bps and the optimal trade size to capture it.”
Automated agent execution routing
“My trading bot needs to sell cbBTC on Base — find the DEX that pays the most for cbBTC/USDC and tell me the best sell venue and how large a trade I can execute before moving the price.”
Technical details
Endpoint
POSThttps://x402.donnyautomation.com/base/route?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time best-execution routing specifically on Base L2 across BaseSwap, SushiSwap, and Uniswap v3. Prefer it over generic price feeds when you need venue-level comparison, spread data in bps, and an optimal trade size in a single call. Choose it over single-DEX price APIs when cross-DEX arbitrage or smart order routing is the goal. If you need the same analysis on Arbitrum One or BSC, use the sibling endpoints for those chains.
Side effects
- Unsupported token pair symbol returns an error or empty result
- Token pair with no liquidity on one or more venues may return incomplete venue comparison
- Network latency or RPC issues on Base L2 may cause stale or failed price fetches
- Malformed pair parameter (wrong format, missing slash) returns a validation error
- Very low liquidity pairs may return zero optimal trade size
