Zernio: Marketing infrastructure for products and agents

Zernio, previously called getlate.dev, has added OpenAI as the 7th ad network in its API, next to Meta, TikTok, Google, LinkedIn, Pinterest and X. Social coverage includes X, Instagram, TikTok, YouTube, Reddit, Bluesky, Threads, Telegram, Discord and Slack. Pricing is free for 2 accounts, then $6/account per month. The company describes itself as a small team from Spain. Zernio says it handles platform changes, token rotations, and rate limits for customers. The company is open about what it does not cover: each platform still has its own content rules, so developers still have to deal with those limits in their own code. Its main competitors are unified social API providers such as Ayrshare. For AI founders, the selling point is distribution that agents can run directly. Agents that publish posts, run ad campaigns or answer customer messages usually stall on OAuth reviews and platform approvals. Zernio packages that work behind an MCP server, so a small team can skip it. The tradeoff is that the team then depends on one vendor's relationships with each platform.
