Any bot for mass account automation?

Hi, I am looking for a reliable software that makes simple tasks (don't need any targeting or else, actually I am only interested in the like feature), but is made to manage 1000 or more accounts efficiently and with API.
Anyone knows such bot?

I already tried GMT2, followliker and jarvee but they are not exatly what is needed for managing a decent amount of accounts.
+ They don't have API and are too slow need something faster

Yes send me a PM

InstaAuto from @Valar Instagramis should be coded for such purposes as far as I know.
