Prepare Sell Transaction

POST 
/transactions/sell/prepare

This endpoint calculates and validates the required inputs for a sell transaction, including accurate pricing estimates, fees, and limits.

Use the endpoint to pre-validate a crypto-to-fiat sell by generating a FormSessionID, retrieving real-time price/fee/limit estimates, computing the required CryptoAuthorizedAmount, and validating payout-form inputs.

This enables the subsequent Create Sell call to execute deterministically within your slippage, balance, and compliance constraints, with no funds being removed at this stage.
