Zernio is marketing infrastructure for products and agents: one API for social, ads, messaging and calls.
Instead of building an integration for every channel, each with its own API, auth and review process, you integrate once, on official platform APIs, and most teams launch the same day.
Social, ads, unified inbox, SMS, RCS, iMessage, WhatsApp, calls and numbers in 57 countries. A hosted MCP server lets agents connect accounts, run campaigns, send messages and place calls on their own.
This is the 4th launch from Zernio. View more

Zernio
Launching today
Zernio is the marketing infrastructure 200,000 developers build products on. We absorb the integrations, platform approvals and maintenance behind every channel, all on official APIs, so you can start building today. One API covers 16 social platforms, ads on 7 networks, WhatsApp, iMessage, and phone numbers with calls and SMS that you buy inside Zernio. Use the REST API in your code, or let your coding agent do the same through our MCP server and CLI.

Couldn’t believe I could push live via Claude so easily.
@natemaggio That’s exactly the kind of experience we want to make possible 😎
Congrats, Miquel and team! Nice to see the extra channels come from what customers were asking for. Keeping the same API as you add them makes sense.
@oleksii_sekundant Thanks, Oleksii! That’s exactly the idea we follow
