As answered by people managing CIENCE and Upload-Post.
Upload-Post's answer:
Upload-Post is the only API that lets you post to 10+ social platforms with a single endpoint. No need to integrate TikTok, Instagram, YouTube, and Facebook APIs separately — one call handles everything. We also offer true white-label: your users connect their accounts directly, so you never touch their credentials.

Upload-Post's answer:
We were building a SaaS and needed to post to multiple social platforms. Integrating each API separately was painful — different auth flows, formats, rate limits, and constant breaking changes. So we built Upload-Post to solve it once. Now thousands of developers use it to skip the headache and ship faster.
