Zernio
Zernio is a unified social media API for developers and AI agent builders. One REST API replaces 15 separate platform integrations, so engineering teams ship social features in hours instead of months. What Zernio covers: - Publish: Post text, images, video, and carousels across 15 platforms. Schedule or publish immediately. Bulk upload via CSV. - Engage: Unified Comments + DMs API across platforms. Auto-reply to comments via DM. Manage engagement programmatically. - Analyze: Pull impressions, reach, engagement, and follower data across all connected accounts into one API response. - Ads: Boost posts, create standalone ads, and manage campaigns across 7 ad platforms (Meta, Google, TikTok, LinkedIn, Pinterest, X, and cross-platform). Platforms supported (15): Instagram, TikTok, X/Twitter, Facebook, LinkedIn, YouTube, WhatsApp, Threads, Pinterest, Reddit, Bluesky, Telegram, Google Business, Snapchat, Discord. Built for developers and AI agents: Zernio handles authentication (OAuth-as-a-service), media formatting, rate limits, and platform API changes, so developers integrate once and Zernio absorbs the maintenance. A hosted MCP server (280+ tools) lets AI agents publish, engage, analyze, and boost autonomously through one tool server. Pricing: Pay per connected account. First 2 accounts free. $6/account (accounts 3–10), $3/account (11–100), $1/account (101–2,000). Every feature included - no add-ons, no plan tiers. X/Twitter API costs passed through at cost. Who uses Zernio: SaaS teams embedding social features, AI agent builders, and agencies managing client accounts at scale. Fully white-label, so end users never see Zernio branding.
