Simulate already-built transactions (standalone)
Standalone simulator that returns predicted output amounts and gas for transactions that are ALREADY built (from any source). This is NOT part of the routing flow and is NOT a prerequisite for /shortcuts/route — route already quotes internally and returns executable calldata in a single call. Do not call this before routing. Use it only to independently simulate/validate arbitrary transactions you already have.
Body
Request to quote multiple transactions
List of input amounts (as decimal strings)
Chain ID (e.g., 1 for Ethereum mainnet)
x >= 01
List of input token addresses

List of transactions to quote
Response
Quote successful
Status of the quote (Success or Error)
Success, Error Output amounts for each output token (as decimal strings)
Error details if the quote failed
Estimated gas for the transaction
"1000000000000000000"
