Do I need a paid plan to connect an AI assistant?

Yes. Creating an aftermarkets API key requires a Pro or Max plan. The AI chat built into the website has a free tier, but connecting external assistants like Claude Desktop or ChatGPT is a paid feature.

Is my API key safe to paste into an AI client?

The key grants access to market data plus your own watchlists and alerts. It cannot place trades, touch your broker account, or change your subscription. Still treat it like a password: keep it out of shared documents, and deactivate it from the Developer dashboard if it ever leaks.

Which AI assistants work with this?

Any client that supports MCP. That includes Claude Desktop, Claude Code, claude.ai, ChatGPT, Cursor, Windsurf, VS Code, Zed, Codex, and Gemini CLI.
