Creator OS docs

Creator OS API

A REST API for everything Creator OS does: publish and schedule to Instagram, TikTok, YouTube, X, Threads, Facebook, LinkedIn, Discord and Slack, message customers on WhatsApp, answer comments and DMs, run comment-to-DM funnels, pull analytics, run your Skool communities, write SEO articles on your WordPress blog, and, with the Ads add-on, paid ads on Meta, Google, LinkedIn, TikTok, X and ChatGPT. Requests and responses are JSON over HTTPS, authenticated with your workspace’s API key.

Base URL

New: MCP server

Use Creator OS inside Claude, ChatGPT and other AI apps

Add this URL as a custom connector, sign in with Creator OS, and pick the workspace and access (read only or read & write). Your AI app can then publish, schedule, read analytics, and answer comments and DMs. No code needed.

Setup for Claude, ChatGPT, Claude Code and Cursor →

Prefer not to write code? The Creator OS CLI wraps every endpoint as a command, and the MCP server puts Creator OS inside Claude, ChatGPT and other AI apps with no code at all.

Quickstart: schedule a video everywhere

Two calls: upload the file, then create the post. Set CREATOROS_API_KEY in your environment first (see Authentication).

# 1. Upload the video
MEDIA_ID=$(curl -s -X POST "https://creatoros-production-5658.up.railway.app/v1/media" \
  -H "Authorization: Bearer $CREATOROS_API_KEY" \
  -H "Content-Type: video/mp4" \
  --data-binary @clip.mp4 | jq -r .id)

# 2. Schedule it to Instagram and TikTok
curl -X POST "https://creatoros-production-5658.up.railway.app/v1/posts" \
  -H "Authorization: Bearer $CREATOROS_API_KEY" \
  -H "Content-Type: application/json" \
  -d @- <<EOF
{
  "content": "New drop 🚀",
  "platforms": ["instagram", "tiktok"],
  "media": ["$MEDIA_ID"],
  "schedule_at": "2026-10-02T18:00:00",
  "timezone": "America/New_York"
}
EOF

Use cases

Step-by-step recipes built on these endpoints: publish everywhere, schedule posts, reply to comments, comment-to-DM funnels and more in the sidebar.
