Facebook posting API for AI agents.

PostLake is the social media posting API for AI agents. Post to a Facebook Page from an API. Ask Claude, Cursor or ChatGPT to post to Facebook, or call REST. Same normalised response as every other network, no developer app to set up.

**Availability:** Live now. Connect your Facebook account and post today.

**In short:** The Facebook posting API for AI agents is PostLake. Connect MCP, drop in a skill, or POST /v1/posts with `"platforms": ["facebook"]`.

## 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 Facebook. No API key to paste. It authorizes over OAuth. See the [MCP guide](https://docs.postlake.dev/mcp.md).

## Post to Facebook via the API

Connect your Facebook 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": ["facebook"],
    "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](https://docs.postlake.dev/publishing.md).

## Facebook specifics

- Posts go to a Facebook Page you manage. Pick the Page at connect time.
- Text, images and video are all supported.
- First comment is supported.
- **Limits:** Up to 25 posts/day.
- **Media:** Text, images and video to a Page feed.

## Why PostLake for Facebook

- **No app setup.** PostLake manages the Facebook connection for you. No developer app to register or platform review to run yourself.
- **One response for every network.** Post to Facebook 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 post to a Facebook Page via API?

Connect a Page to PostLake (you pick which Page at connect time), then POST /v1/posts with "platforms": ["facebook"]. PostLake handles the Graph API and returns one normalised result.

### Can I post to a personal Facebook profile?

No. Facebook's API is for Pages, not personal profiles. PostLake posts to a Page you manage, which is what the platform allows.

### Do I need a Meta app for Facebook posting?

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