Platform Capabilities

The rules of each platform as data, so your integration doesn’t have to hard-code them: caption and title limits, the daily post cap, accepted media, and the settings a platform requires.

Endpoint

GET /api/v1/platforms/capabilities

Requires x-api-key.

Query parameter	Required	Description
`platform`	No	One of `tiktok`, `instagram`, `facebook`, `linkedin`, `bluesky`, `threads`, `pinterest`, `youtube`, `x`. Without it, all platforms are returned as an array.

Example


curl "https://api.multi-upload-tool.com/api/v1/platforms/capabilities?platform=tiktok" \
  -H "x-api-key: YOUR_API_TOKEN"


{
  "success": true,
  "data": {
    "platform": "tiktok",
    "limits": {
      "postCharacters": 2200,
      "photoPostCharacters": 4000,
      "titleCharacters": 90,
      "altTextCharacters": null,
      "linkCharacters": null,
      "tagsCharacters": null
    },
    "dailyPostCap": 15,
    "mediaSupport": { "kinds": ["video", "image"], "maxCount": 35, "...": "..." },
    "settingsSchema": {
      "privacyLevel": { "required": true, "type": "enum", "values": ["PUBLIC_TO_EVERYONE", "MUTUAL_FOLLOW_FRIENDS", "SELF_ONLY"] }
    },
    "bannedHashtags": []
  }
}

A null limit means the platform has no such field. Over MCP, the same data is the get_platform_capabilities tool. To check a full post against these rules, use Validate a Post.
