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
Launched this week
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.

Hey Product Hunt, Darya here, I do marketing & growth at Zernio 😊
funny thing: the product I market today isn’t the one I joined. It started as an API for posting to social, and now we offer our users so much more! Ads, WhatsApp, iMessage, phone numbers, calls and SMS too. All of it is available as tools for your agents too. This is the first time we’re showing all of it together.
What I’d love to hear from you: what are you building, or trying to build, that you can’t with Zernio yet? We read every comment, and a lot of what we’ve built started as exactly that kind of reply.
I've been using Zernio for about 2 months, what initially drove me to it was the better value compared to other more popular options (at that time). They ship lots of features really quickly, I'm really happy with it so far, best of luck.
@rolando_lopez2 Thanks so much, Rolando! Appreciate the support! 🙌
Zernio is part of my tech stack for over 6 month now. The ease for development within our software, the great support from the team and ongoing improvements to their products and line-up prove to me that Zernio is here for the long-run. I recommend it to everyone who is looking for a proper social media scheduling and all-in-one inbox solution (the two products we have integrated so far).
how many tools does the agent see through the MCP with all 16 platforms plus ads and calls? from our experience at ApyHub the tool list gets long fast, that's why our MCP is just 4 generic tools
@nikolas_dimitroulakis 496 in the full catalog, but your agent only sees about 50 of them.
The rest sit behind two generic tools: search_tools finds one by description, call_tool runs it
congrats team,
a great agentic work to pilot my video submission, works very smooth.
@ludobos great, thank you for the support, Ludovic!
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
Couldn’t believe I could push live via Claude so easily.
@natemaggio That’s exactly the kind of experience we want to make possible 😎
