How this service works
DeFi data for AI agents — yield rates, swap routes, IL calculator, liquidation risk, MEV scanner, TVL tracking. Powered by DeFiLlama + on-chain RPC data. Pay with USDC on Base via x402.
Output
Returns a best_route object with the optimal swap path, an all_routes array listing every discovered route ranked by efficiency, the total number of routes found, and echoed inputs including from/to token symbols, chain, and amount in USD.
Example use cases
Optimal token swap before DeFi trade
“I want to swap $2000 worth of WBTC into USDC on Ethereum — find me the best DEX route so I get the most USDC for my money.”
Cross-DEX arbitrage route scouting
“Compare all available swap routes from ARB to ETH on Arbitrum for a $500 trade and tell me which one is the most efficient.”
Stablecoin swap routing
“I need to convert $1000 USDC to DAI on Base — which swap route gives me the best rate right now?”
Technical details
Endpoint
POSThttps://aracil.vercel.app/api/best-routeWhen to prefer
Use this endpoint when an AI agent needs to programmatically identify the best on-chain swap route between two tokens before executing a trade, or when comparing DEX routing options across liquidity pools. It is particularly useful for agents managing DeFi portfolios, executing token swaps optimally, or building trade strategies that require route-level detail rather than just a price quote.
Side effects
- Unsupported token symbols result in no routes found
- Invalid or unsupported chain name causes an error response
- Token pair with no liquidity returns empty routes array
- Malformed request body missing required fields returns validation error
- Network or RPC connectivity issues may cause timeouts or stale data
