# PostFast

Schedule social media posts across 9 platforms from one API. SaaS — no self-hosting needed.

## Setup

1. Sign up at https://app.postfa.st/register
2. Go to Workspace Settings → generate an API key
3. Set the environment variable:
   ```bash
   export POSTFAST_API_KEY="your-api-key"
   ```

Base URL: `https://api.postfa.st`
Auth header: `pf-api-key: $POSTFAST_API_KEY`

## Core Workflow

### 1. List connected accounts

```bash
curl -s -H "pf-api-key: $POSTFAST_API_KEY" https://api.postfa.st/social-media/my-social-accounts
```

Returns array of `{ id, platform, platformUsername, displayName }`. Save the `id` — it's the `socialMediaId` for posting.

### 2. Schedule a text post (no media)

```bash
curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [{
      "content": "Your post text here",
      "mediaItems": [],
      "scheduledAt": "2025-06-15T10:00:00.000Z",
      "socialMediaId": "ACCOUNT_ID_HERE"
    }],
    "controls": {}
  }'
```

### 3. Schedule a post with media (3-step flow)

**Step A** — Get signed upload URLs:
```bash
curl -X POST https://api.postfa.st/file/get-signed-upload-urls \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "contentType": "image/png", "count": 1 }'
```
Returns `[{ "key": "image/uuid.png", "signedUrl": "https://..." }]`.

**Step B** — Upload file to S3:
```bash
curl -X PUT "SIGNED_URL_HERE" \
  -H "Content-Type: image/png" \
  --data-binary @/path/to/file.png
```

**Step C** — Create post with media key:
```bash
curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [{
      "content": "Post with image!",
      "mediaItems": [{ "key": "image/uuid.png", "type": "IMAGE", "sortOrder": 0 }],
      "scheduledAt": "2025-06-15T10:00:00.000Z",
      "socialMediaId": "ACCOUNT_ID_HERE"
    }],
    "controls": {}
  }'
```

For video: use `contentType: "video/mp4"`, `type: "VIDEO"`, key prefix `video/`.

### 4. List scheduled posts

```bash
curl -s -H "pf-api-key: $POSTFAST_API_KEY" https://api.postfa.st/social-posts
```

### 5. Delete a scheduled post

```bash
curl -X DELETE -H "pf-api-key: $POSTFAST_API_KEY" https://api.postfa.st/social-posts/POST_ID
```

### 6. Cross-post to multiple platforms

Include multiple entries in the `posts` array, each with a different `socialMediaId`. They share the same `controls` and `mediaItems` keys.

## Platform-Specific Controls

Pass these in the `controls` object. See [references/platform-controls.md](references/platform-controls.md) for full details.

| Platform | Key Controls |
|---|---|
| **TikTok** | `tiktokPrivacy`, `tiktokAllowComments`, `tiktokAllowDuet`, `tiktokAllowStitch`, `tiktokIsDraft`, `tiktokBrandContent`, `tiktokAutoAddMusic` |
| **Instagram** | `instagramPublishType` (TIMELINE/STORY/REEL), `instagramPostToGrid`, `instagramCollaborators` |
| **Facebook** | `facebookContentType` (POST/REEL/STORY) |
| **YouTube** | `youtubeIsShort`, `youtubeTitle`, `youtubePrivacy`, `youtubePlaylistId`, `youtubeTags`, `youtubeMadeForKids` |
| **LinkedIn** | `linkedinAttachmentKey`, `linkedinAttachmentTitle` (for document posts) |
| **X (Twitter)** | `xQuoteTweetUrl` (for quote tweets) |
| **Pinterest** | `pinterestBoardId` (required), `pinterestLink` |
| **Bluesky** | No platform-specific controls — text + images only |
| **Threads** | No platform-specific controls — text + images/video |

## Helper Endpoints

- **Pinterest boards**: `GET /social-media/{id}/pinterest-boards` → returns `[{ boardId, name }]`
- **YouTube playlists**: `GET /social-media/{id}/youtube-playlists` → returns `[{ playlistId, title }]`

## Rate Limits

- 60/min, 150/5min, 300/hour, 2000/day per API key
- Check `X-RateLimit-Remaining-*` headers
- 429 = rate limited, check `Retry-After-*` header

## Tips for the Agent

- Always call `my-social-accounts` first to get valid `socialMediaId` values.
- For media posts, complete the full 3-step upload flow (signed URL → S3 PUT → create post).
- `scheduledAt` must be ISO 8601 UTC and in the future.
- Pinterest always requires `pinterestBoardId` — fetch boards first.
- LinkedIn documents use `linkedinAttachmentKey` instead of `mediaItems`.
- For carousels, include multiple items in `mediaItems` with sequential `sortOrder`.
- TikTok video thumbnails: set `coverTimestamp` (seconds) in `mediaItems`.
