Upload Videos🎥, Photos📸 & Text🖊️ to TikTok, Instagram, YouTube, X, LinkedIn, Facebook, Threads, Pinterest, Reddit & Bluesky via Upload-Post API

Upload content to social media platforms via Upload-Post API. Use when posting videos, photos, text, or documents to TikTok, Instagram, YouTube, LinkedIn, Facebook, X (Twitter), Threads, Pinterest, Reddit, or Bluesky. Supports scheduling, analytics, FFmpeg processing, and upload history.

Security Scan

The skill is an instruction-only wrapper for a third‑party “upload-post.com” API and its declared requirements and instructions are consistent with that purpose.

Purpose & Capability

The name/description match the SKILL.md: it documents a single external service (upload-post.com) for posting to many social platforms. There are no unexpected environment variables, binaries, or install steps requested that would be unrelated to a posting/scheduling service.

Instruction Scope

The instructions show curl examples that upload local files (e.g., -F "video=@video.mp4") and reference an /ffmpeg endpoint plus local ffmpeg CLI examples in references. That is reasonable for a posting tool, but it means the agent will need access to any files you ask it to upload. The SKILL.md does not instruct the agent to read unrelated system files or secrets.

Install Mechanism

This is instruction-only (no install spec, no code files to execute). No downloads or third‑party installs are required by the skill itself.

Credentials

The documentation expects an API key from upload-post.com (Authorization: Apikey). The skill does not request other credentials or unrelated environment variables—proportional to the described functionality.

Persistence & Privilege

always is false and there is no installation that writes persistent config. Model invocation is enabled by default (normal for skills); there are no combined red flags that would make autonomous invocation unusually risky.

Assessment

This skill is a documentation guide for a third‑party service (upload-post.com). Before enabling or using it: verify the service's trustworthiness and privacy/terms; only provide an API key you control and rotate it if needed; avoid uploading sensitive files or secrets through the service; test with a non‑production profile first; limit which social accounts/pages you connect; and be aware the agent (if allowed to run autonomously) could post using that API key — only enable autonomous actions if you trust the service and the skill.

Upload-Post API

Post content to multiple social media platforms with a single API call.

Documentation

• Full API docs: https://docs.upload-post.com
• LLM-friendly: https://docs.upload-post.com/llm.txt

Setup

1. Create account at upload-post.com
2. Connect your social media accounts
3. Create a Profile (e.g., "mybrand") - this links your connected accounts
4. Generate an API Key from dashboard
5. Use the profile name as user parameter in API calls

Authentication

Authorization: Apikey YOUR_API_KEY

Base URL: https://api.upload-post.com/api

The user parameter in all endpoints refers to your profile name (not username), which determines which connected social accounts receive the content.
