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 structured object containing the best recommended swap route, a list of all discovered routes across DEXes, the number of routes found, and echoed input parameters (from token, to token, chain, amount in USD). The best_route object details the specific protocol path and pricing for the optimal trade.

Technical details
Endpoint
POSThttps://defi-oracle-two.vercel.app/api/best-routeWhen to prefer
Use this endpoint when an AI agent needs to find the most efficient on-chain swap path between two specific tokens before executing a trade, or when comparing DEX routes to minimize slippage and fees. Best suited for pre-trade analysis on supported chains where DeFiLlama aggregation data is available.
Side effects
- Unsupported token symbol returns empty routes or error
- Chain not supported returns no routes found
- No liquidity available for the pair returns routes_found: 0
- Invalid token symbol format causes request validation error
- Network RPC connectivity issues may cause timeouts or stale data
