Built by developers, for developers
We're a small team from Spain building the social media API we wished existed. One integration, every platform, zero headaches.
Our story
We were working on a side project that needed to post to a few social platforms. Should be easy, right? It wasn't. TikTok wants one thing, Instagram wants another, LinkedIn does its own thing entirely. We spent more time fighting their APIs than building our actual product.
So we thought: what if there was just one API for all of this? Not just posting, but the whole thing. Comments, DMs, analytics, webhooks. That's Zernio. You integrate once and get 14 platforms. We deal with the OAuth headaches, the media transcoding, the rate limits, and the random breaking changes so you don't have to.
There are four of us, spread across Spain. We took no money and we like it that way. Tens of thousands of API requests go through Zernio every day, and we still get excited about every new one.
Things we care about
- The API comes first
- Everything we build starts as an endpoint. If it's not in the API, it doesn't ship.
- Don't waste people's time
- You can sign up, grab a key, and make your first API call in minutes. No demos, no forms.
- Stay small, move fast
- We're four people and that's not a limitation. Less overhead, more shipping.
- Show your work
- Public changelog, status page, and full logs for every API call we make on your behalf. No black boxes.
