Help with poshmarks new phone verification update

Poshmark just added a new feature to there app/site where you need to put in a phone number BEFORE you make a listing then one again after you make a sale and its time to reedeem. My poshmakr straetgy that works best for me is having multiple accounts with a bot I have that creates it. I need you to help me find the best solution & or NON Voip servicer that can work for this issue. Ideally i need a servicer that has API so the bot can handle all of the accounts made and i dont have to do it manually
