GHL API Docs

The entire GoHighLevel API v2.0 documentation, ripped from the Marketplace and converted to clean Markdown so you (and your AI agents) don't have to.

---

Why This Exists

If you've ever tried to get an AI agent, MCP server, or coding assistant to work with GoHighLevel's API, you know the pain. The docs live behind the GHL Marketplace login, scattered across 350+ pages. AI crawlers can't reach them. Firecrawl tokens aren't cheap. And copy-pasting endpoint specs into ChatGPT gets old fast.

So we burned the Firecrawl tokens, crawled the whole thing, and organized it into Markdown files that any LLM, agent, or search engine can index and use.

You're welcome.
