How this service works
Pay-per-call web and onchain utilities for AI agents (MPP + x402, USDC on Base).
Output
Returns the optimal swap route details including the routing path across liquidity sources, expected output token amount, price impact, gas estimates, and any intermediate hops needed to complete the exchange.
Example use cases
Cross-chain token bridge routing
“I want to move 1000 USDC from Base to Ethereum as ETH — what's the best swap route from my address 0xDe...456? Keep slippage under 1%.”
Same-chain DeFi swap quote
“Get me a swap route to exchange 2 WETH for USDC on Base from address 0xAb...789, with 0.5% slippage.”
Portfolio rebalancing route lookup
“I need to convert 300 DAI to WBTC on Base from wallet 0xFe...321 — find the optimal route and show me the expected output amount with 0.3% slippage.”
Technical details
Endpoint
POSThttps://red-web-utils.agent-tools-x402.workers.dev/api/swap/route?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to look up swap routing and pricing information for onchain token exchanges without executing a transaction — ideal for quoting, planning, or presenting trade options to users. It supports cross-chain routing, making it suitable for multi-chain DeFi workflows. Prefer this over on-chain direct calls when you need a simple, pay-per-call REST interface priced in USDC via x402.
Side effects
- Unsupported token pair returns an error or empty route
- Invalid fromAddress format causes a validation error
- fromAmount of zero or negative triggers a bad request error
- Insufficient liquidity for the requested pair returns no viable route
- Unsupported chain identifier causes a lookup failure
- Network timeouts when querying DEX aggregators
