In shortThe YouTube posting API for AI agents is PostLake. Connect MCP, drop in a skill, or POST /v1/posts with "platforms": ["youtube"].

The fastest way: ask your agent

Connect PostLake's hosted MCP server to your AI assistant (Claude, ChatGPT, Cursor and others), then just ask it to post to YouTube. No API key to paste. It authorizes over OAuth. See the MCP guide.

Post to YouTube via the API

Connect your YouTube account, then one call publishes to it (and any other accounts under the profile). Upload media first to get a med_… id, then include it:

curl -X POST https://api.postlake.dev/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Hello from PostLake 👋",
    "platforms": ["youtube"],
    "profile": "my-brand",
    "media": ["med_abc"]
  }'

You get back one normalised shape. A post id plus a targets list with the live URL. Full detail in Publishing a post.

Why PostLake for YouTube

No app setup

PostLake manages the YouTube connection for you. No developer app to register or platform review to run yourself.

One response for every network

Post to YouTube and other networks in one call and get back a single normalised shape. Your code never branches per platform.

Agent-safe

Idempotency keys mean a retrying agent never double-posts, and analytics come back normalised so an agent can decide what to post next.

Honest pricing

A free tier to start, then usage-based credits. One per post (X costs more). You only pay for posts that actually publish.

Common questions

How do I upload to YouTube via API?

Connect your YouTube channel to PostLake, upload a video to get a media id, then post with "platforms": ["youtube"]. PostLake handles the YouTube Data API upload and returns one normalised result.

Can I pick which YouTube channel to post to?

Yes. At connect time you choose the channel (including Brand Accounts) through Google's own account chooser.

Do I need YouTube API approval?

YouTube uses a quota-based, verified-app model. PostLake handles that on the managed side, so there's nothing for you to verify. You connect your channel and upload.
