API reference for Sprinter Solve — request an optimal swap route and execute the returned call data
Sprinter Solve enables efficient, intent-based swap execution through the Solve API, powered by the Sprinter Solver (built on the Project Blanc solver). You request a route for a token swap and receive the executable call data, optimized for best price with MEV protection and low slippage.
Detect an intent — a user wants to swap one token for another.
Get a route — call GET /v1/route with the input amount, token in/out, and slippage (in basis points). The response includes amountOut, minAmountOut, the target contract, the executable callData, and gas estimates.
Execute — send a transaction to target with callData from the user’s wallet to fulfill the swap on-chain.
Re-query /v1/route before execution if there is a delay, and simulate the call data (e.g. with Tenderly) before sending.
