You knew Zernio as the API for social media. Now it does WhatsApp too, the whole thing. Connect a number and you've got the entire WhatsApp Business API behind it: messaging and broadcasts, in-chat forms, calls you can route to AI agents, chatbots, group chats, and numbers in 53 countries. Whatever you need to build on WhatsApp, it's one integration. Made for developers and the agents they build: REST, SDKs, CLI, and a hosted MCP server. Official WhatsApp Business API. Zero markup on usage.

Building ad integrations with Meta, Google, TikTok, LinkedIn, Pinterest, and X means 6 developer apps, 6 OAuth flows, 6 campaign object models, and months of engineering. Zernio replaces all of that with a single endpoint. No developer app required. Bearer token auth. One normalized data model. The Ads API joins Zernio's existing social layer: publishing, comments, DMs, and analytics across 15 platforms.

Build social media features at scale. Zernio provides a single API for publishing, inbox, analytics, and account management across 14 platforms, so you can ship product instead of wasting time with platform APIs.
