Post to Threads

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

Availability: Live now — connect a Threads 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 Threads. No API key to paste — it authorizes over OAuth. See the MCP guide.

Post to Threads via the API

Connect your Threads account, then one call publishes to it (and any other accounts under the profile). No media required for a text post:

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": ["threads"],
    "profile": "my-brand"
  }'

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

Media: Text, image carousels and video.

Why PostLake for Threads

No app setup

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

One response for every network

Post to Threads 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 to Threads?

Yes — Threads has a publishing API and PostLake wraps it. Post with "platforms": ["threads"] and PostLake returns the same normalised shape as every other network.

Can an AI agent post to Threads?

Yes — connect PostLake's MCP server to your assistant and ask it to post to Threads. No key to paste.

Do I need app approval for Threads?

Threads posting via API requires Meta app-review — but PostLake runs the managed app, so there's no review for you to pass yourself.
