Overview

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.

Base URL

The Swap API is served per network:

https://swaps.sprinter.tech/mainnet
https://swaps.sprinter.tech/base

Authentication

All requests use HTTP Basic authentication. Your credentials are a username and an API key (format sk_live_*) used as the password:

curl --user 'YOUR_USERNAME:YOUR_API_KEY' \
  'https://swaps.sprinter.tech/base/v1/route?tokenIn=0x833589fcd6edb6e08f4c7c32d4f71b54bda02913&tokenOut=0x50c5725949a6f0c72e6c4a641f24049a917db0cb&amountIn=5000000000&slippageBps=50'

Request Solve API credentials by contacting [email protected].

How it works

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.

Endpoints

Endpoint	Description
`GET /v1/route`	Get an optimal swap route and execution call data

Response format

GET /v1/route returns the route and the call data needed to execute the swap:

{
  "requestId": "0x...",
  "amountOut": "99850000",
  "minAmountOut": "99350000",
  "target": "0x...",
  "callData": "0x...",
  "gasUsed": 180000,
  "gasLimit": 234000
}

Re-query /v1/route before execution if there is a delay, and simulate the call data (e.g. with Tenderly) before sending.
