One API for Instagram, TikTok, YouTube, X, LinkedIn, Facebook and Threads

Instead of integrating seven social media APIs, each with its own app review, token refresh and posting rules, you can use one: the Creator OS API. One key publishes, schedules, replies and reads analytics across Instagram, TikTok, YouTube, X, LinkedIn, Facebook and Threads.

What you can build with it

• Publishing: text, images, carousels, short and long video, and stories, to one account or many in one call.
• Scheduling: pass a time and timezone and the post goes out from our servers.
• Inbox: list comments and DMs across networks, reply, hide, like or delete.
• Automations: keyword comment-to-DM funnels.
• Analytics: per-post metrics, daily totals, follower growth and best time to post.
• Webhooks: get events like new comments and published posts pushed to your server, signed.

How authentication works

Every workspace has its own API key starting with cos_live_. A key only sees its own workspace, so an agency can hand one client’s key to an agent without exposing any other client. You can also create read-only keys for agents that should only report. See Authentication.

A first call

Upload a video, then create the post:

curl -X POST https://creatoros-production-5658.up.railway.app/v1/posts \
  -H "Authorization: Bearer $CREATOROS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content":"New video","platforms":["instagram","tiktok","youtube"],"media":["med_..."]}'

Every endpoint has cURL, JavaScript and Python examples in the API reference.

Built for AI agents

The same API powers the MCP connector and the @creatoros/cli command line tool, which ships agent skills so tools like Claude Code know how to run your socials safely.

Frequently asked questions

Do I need my own developer apps on each network?

No. You connect your accounts in Creator OS and use one key.

Can I use it for clients?

Yes. Agency plans give each client its own workspace and key.

Try it

Creator OS plans start at $19.99/month and include the API, the MCP connector for Claude and ChatGPT, and the CLI. Create your account, connect your socials, and hand your key to an agent.
