Zernio WhatsApp API

About

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.
