I'm the founder of  an unofficial TikTok API.
It started as a small side project, but now it has been growing quickly and we even have clients from Fortune-500 companies.The next step is registration as a corporate, fund-raising, hiring, and some other stuff that are necessary for a company to grow.But I'm not sure if that's legal or what kind of troubles we will have from TikTok.So far, we have only been contacted by TikTok representatives for a trademark issue, though they were helpful and we fixed the issue quickly.
