AI Agent Social Media Posting API: Post Videos to TikTok, Reels, Shorts, X, and Facebook

AI agents can write captions, prepare campaign ideas, and organize content workflows. But if they cannot publish the video, the user still has to open every social app, upload the file, paste the caption, and check the result manually.

Taisly Agent Kit closes that gap through Taisly. It gives AI agents and developer tools a JSON-first CLI and SDK for social media video publishing.

Agents can create, but they still need a publishing layer

Taisly Agent Kit gives agents a real posting workflow

Taisly handles connected social accounts and posting execution. The agent handles planning, copywriting, validation, and orchestration. Together they create a practical video publishing API workflow for creators, developers, and marketing teams.

You can read the Taisly API docs, open the Agent Kit quickstart, or install the package from npm.

How it works

Create a Taisly account.
Connect TikTok, Instagram, YouTube, X, Facebook, or other social accounts.
Create an API key in Taisly Settings.
Install the Agent Kit package.
Let your agent publish with a safe JSON workflow.

npm install -g @taisly/agent
export TAISLY_API_KEY="taisly_..."
taisly auth:status
taisly platforms:list

Agents can create a JSON payload:

{
  "video": "./launch.mp4",
  "platforms": ["platform_id_1"],
  "description": "Launch day. Short demo, big update.",
  "scheduled": "2026-06-14T09:00:00+07:00"
}

Then validate and publish:

taisly posts:validate --json ./campaign.json
taisly posts:create --json ./campaign.json
taisly posts:status --id <historyId>

Use cases

Use it for TikTok API posting automation, Instagram Reels automation, YouTube Shorts publishing, X and Facebook video posting, or any local agent workflow that needs to move from prepared content to a live post.

If your AI agent can prepare the post, Taisly Agent Kit can help it publish the post.
