Best Social Media APIs (2026)
Last fact-check: July 2026
If you want to publish from your own product or automation, you need an API — not a scheduler UI with a webhook bolted on. We tested 6 tools that ship a proper REST API, from $2.99 per account to enterprise unified endpoints.
The good news, in July 2026, is that pricing is finally sane. Upload-Post offers unlimited uploads with server-side FFmpeg from about $16 a month, Zernio drops below $3 per account at scale, and Publora starts at $2.99. You no longer need an Ayrshare-sized budget to get a working posting API.
