No card for the free tier · one API for every network · full MCP access

Availability: Live now — connect a TikTok account and post today.

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 TikTok. No API key to paste — it authorizes over OAuth. See the MCP guide.

Post to TikTok via the API

Connect your TikTok 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": ["tiktok"],
    "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.

TikTok specifics

TikTok is video-only: every post needs a video asset.
Publishing is asynchronous — PostLake accepts the post, then a status poller resolves it to published or failed, so your code (or agent) knows the real outcome.
Creator-level options (privacy, comments, duet/stitch) are fetched live so you only offer valid choices.
Limits: About 15 posts/day.
Media: Video required — TikTok is video-only.

Why PostLake for TikTok

No app setup

PostLake manages the TikTok connection for you — no developer app to register or platform review to run yourself.

One response for every network

Post to TikTok 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

Is there an API to post videos to TikTok?

Yes — TikTok has a content-posting API and PostLake wraps it. Upload a video to PostLake, then post with "platforms": ["tiktok"]; PostLake handles the async publish and reports the final state.

Can I schedule TikTok posts via API?

Yes — send a scheduledAt time and PostLake fires the post at the right moment, with a webhook the instant it goes live or fails.

Do I need TikTok app approval?

TikTok requires an app audit before public posting — but PostLake runs the managed app, so there's no audit for you to pass yourself.
