api.tollboothswap.xyz/v1/swap/build

Non-custodial swap execution for AI agents on 8 chains: Solana (Jupiter) plus Base, Ethereum, Arbitrum, Polygon, Optimism, BSC and Avalanche (0x). Pay a small toll to get an unsigned, fee-inclusive swap transaction and an HMAC-signed receipt for auditing. Comparison-shop first with free indicative quotes at GET /v1/quote (same parameters, no taker required). You sign and submit with your own wallet - Tollbooth never touches keys or funds.
