What’s next?

Document Search

Build semantic search across thousands of documents for your users

OCR Integration

Add document digitization to extract text from scanned PDFs

Audio Transcription

Enable your users to convert audio recordings to searchable text

Authentication

Get your API key from the Console. You get $10 free usage** every month, or **$30/month when you add a payment method.

All requests require your API key in the Authorization header:

Shell

Authorization: Bearer sk_case_YOUR_API_KEY

Keep your API key secret. Don’t commit it to version control. Use environment variables.

Connect from your AI client

If you already live in Claude, ChatGPT, or Microsoft 365 Copilot, connect Case.dev there instead of building a separate wrapper first.

Claude

Add Case.dev as a remote MCP connector in Claude and authenticate with OAuth.

ChatGPT

Connect Case.dev to ChatGPT’s remote MCP flow for chat and research tools.

Copilot

Package Case.dev into a Microsoft 365 Copilot declarative agent.
