Query CreatorBase from your own code

The same data behind the app: breakout videos, AI-made channels, similar-channel matching, breakout alerts and trending niches. JSON in, JSON out.

Authentication

Use the same personal key that powers the MCP connector. If you have already connected CreatorBase to Claude or ChatGPT, your key works here with nothing further to set up. Create one under API keys and send it as a bearer token.
