Description
Zernio is a unified social media API platform that enables developers and AI agents to publish, schedule, and manage content across 14+ social networks through a single integration. Instead of building and maintaining separate integrations with each platform's API, developers make one API call and Zernio handles authentication, media formatting, rate limits, and platform-specific requirements.
The platform supports Instagram Business and Creator APIs, TikTok Business API, LinkedIn Company and Personal APIs, YouTube Data API, Twitter/X API, Facebook Graph API, Meta Business Suite, Pinterest API, Google My Business API, Reddit API, Threads API, Bluesky API, and WhatsApp Business API. Key capabilities include post scheduling and publishing, content management across all platforms, comments and DMs automation, analytics tracking, ads management, media upload and management, webhook notifications, rate limit management, and automatic token refresh.
Zernio is designed for developers and technical teams building products that require social media functionality, including SaaS companies embedding social features into their own products, agencies managing client accounts at scale, and AI agent builders who need programmatic social posting. The product is white-label, meaning end users never see Zernio branding. Developer-friendly SDKs and comprehensive API documentation support fast implementation, reducing integration time from months to under an hour. A free version and free trial are available, with usage-based pricing.
