Product
Problem
Developers building social media and customer communication features must integrate separately with each platform's proprietary API, each with its own authentication flow, rate limits, media requirements, and breaking changes. This fragmentation forces engineering teams to write and maintain custom code for every channel, consuming significant development time and creating ongoing maintenance burdens that distract from core product work.
Solution
Zernio provides a single unified API that connects developers and AI agents to 16 social, messaging, and advertising platforms through one integration. The platform abstracts away platform-specific complexities including OAuth handshakes, token rotations, media transcoding, and rate limiting, allowing users to publish posts, schedule content, reply to comments and DMs, pull analytics, and manage ad campaigns across all major networks from a single endpoint. Zernio also offers telephony capabilities for voice calls, SMS, and WhatsApp messaging, plus an MCP server that lets AI agents connect to the platform using natural-language setup prompts. Developers can sign up, obtain an API key, and make their first call in minutes without demos or approval forms, with full transparency through a public changelog, status page, and itemized usage logs.
Target Audience
Primary customers are software developers, product teams, and AI agent builders who need to integrate social media publishing, messaging, and advertising capabilities into their applications without maintaining multiple platform-specific integrations.
