What is Zernio?

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.

What is Postproxy?

Postproxy streamlines the integration process by merging various platform-specific connections into one unified REST endpoint. With this approach, you can send a single request that encompasses your content and selected profiles, enabling Postproxy to handle the complexities of format conversion, OAuth authorizations, token renewals, rate limiting, retries, and customized delivery for each platform, while also providing structured results for every network. Beyond just content publishing, it manages post interactions, replies to Google Business reviews, and collects profile and follower statistics, effectively enhancing the overall posting experience through a single, comprehensive API. The platforms supported by Postproxy include Instagram, Facebook, Threads, TikTok, X, YouTube, LinkedIn, Pinterest, Bluesky, Telegram, and Google Business, with Reddit anticipated to be added shortly. The service offers official SDKs for a variety of programming languages, including TypeScript, Python, Ruby, Go, Java, .NET, and PHP, and it comes equipped with webhooks, an MCP server for AI integrations, and compatibility with automation tools like n8n, Zapier, Make, and Needle. Tailored for SaaS applications, automated workflows, and agency requirements, Postproxy is hosted within the EU and complies with GDPR regulations. Users can easily begin with a free tier that does not necessitate a credit card, making it accessible to a broad audience. Moreover, its extensive capabilities empower agencies to manage their social media presence more effectively than ever, ensuring they can adapt to the rapidly changing digital landscape. With Postproxy, organizations can focus on their core objectives while relying on a powerful tool to handle the intricacies of social media management.
