## Description
Build a social media automation with Zernio: one API key to post, analyze and reply across your accounts, without an OAuth app on every platform.

If you're building an app, an automation or an agent that touches social, the AI is the easy part. The hard part is creating a developer app on every platform, waiting weeks for review, wiring up each OAuth flow, then maintaining tokens and chasing breaking API changes forever. This walks through the full build, end to end, using Claude Code as the agent.
