Zernio Reviews & Product Details

Zernio is marketing infrastructure for products and AI agents: one API for social, ads, messaging and calls. Developers build it into their products. AI agents use it to do the work for them. Without Zernio, every channel is a separate integration, with its own API, authentication and review process. That's months of work. With Zernio, it's one integration, built on official platform APIs, and most teams launch the same day. What Zernio covers: ➔ Social: Publish, schedule and analyze posts on 15+ platforms, including Instagram, TikTok, LinkedIn, YouTube, X, Facebook, Threads, Pinterest, Reddit and Bluesky. ➔ Unified Inbox: Comments, DMs and replies from every channel in one API. ➔ Ads: Manage campaigns on 7 ad platforms, from Meta and Google to OpenAI Ads. ➔ Messaging: SMS, MMS, RCS, iMessage and WhatsApp, with US carrier registration handled through the API. ➔ Calls: Inbound, outbound and browser calling. Route calls to AI voice agents like Vapi, Retell and ElevenLabs, with optional recording and transcription. ➔ Phone numbers: Real numbers in 57 countries for calls, texts and WhatsApp. For AI agents: a hosted MCP server with 490+ tools and CLI let agents connect accounts, run campaigns, send messages and place calls on their own. Zernio handles authentication, rate limits and platform changes. You integrate once, and we take care of the maintenance. Pricing: Social is priced per connected account, with the first 2 free. Phone numbers start at $3/month. Messages and call minutes are billed by usage. Who uses Zernio: SaaS teams, AI agent builders and agencies managing client accounts at scale. Fully white-label, so end users never see Zernio branding.
