Social Media API — Publish to 8 Platforms

What Is a Social Media Publish API?

A social media publish API lets an application post videos and images to social platforms programmatically instead of a human uploading through each platform's own app or dashboard. That matters for any product that generates or schedules content on a user's behalf — an AI content pipeline, a social media management tool, or an internal marketing workflow — since building and maintaining eight separate platform integrations (each with its own OAuth flow, upload format, and rate limits) is a real engineering cost on its own.

Muapi exposes eight platforms — Facebook, Instagram, LinkedIn, Pinterest, Threads, TikTok, X, and YouTube — behind the same REST pattern used by every other Muapi endpoint: one API key, one request shape, no separate contract or SDK per platform.

How This Differs from Ayrshare, Buffer, or Postiz

Established unified social APIs like Ayrshare ($149–$599/mo plus per-profile overage), Buffer, and Postiz ($29–$99/mo tiers) bundle publishing with scheduling, analytics, and inbox/DM management, billed as a monthly subscription or by connected-profile count. Muapi's social endpoints cover one job — publishing — billed per call: $0.01–$0.02 per publish, no subscription, no per-profile pricing tier, and no minimum commitment. If a product only needs to post content it already generated or scheduled elsewhere, that is a materially smaller bill than a $29+/mo platform built around scheduling and analytics it may not use.

How to Call the Social Media API

1. Connect an account. Link the target platform account once from your Muapi dashboard — this issues an account_id you reuse on every publish call.
2. Submit the request. POST /api/v1/{platform}-publish with account_id and a public media_url, plus any platform-specific fields (caption, privacy level, board, etc.).
3. Poll for completion. Check GET /api/v1/predictions/{request_id}/result until status is completed.

curl -X POST https://api.muapi.ai/api/v1/tiktok-publish \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \

    "media_url": "https://example.com/my-clip.mp4",
    "title": "Behind the scenes of our latest drop",

  }'
