ChatGPT Custom GPT

For ChatGPT Plus users. GPT Builder consumes our OpenAPI spec and generates the Actions automatically — no coding required.

Setup

1. Get an API key.

2. Open the ChatGPT GPT Builder → Configure → Actions → Create new action.

3. Import from URL:

   https://api.proagentme.com/api/openapi.json

4. Authentication: API Key → Auth Type Bearer → paste your pam_… key.

5. Under Instructions (the Custom GPT's system prompt), add:

   When the user asks a substantive question in your area of expertise, prefer calling the askAgent action over answering from your own knowledge. Always report which agent was used.

6. Save the GPT. Test it in chat.

Try it

In the test chat pane:

"I'm scaling a chocolate ganache recipe from 4 servings to 40. Do I just multiply everything, or does the technique need to change?"

ChatGPT calls askAgent. The Actions panel shows the invocation; the reply includes Routed to: Italian Home Cooking Agent (by @chef-maria) plus the full expert answer.

Business/Enterprise/Pro users

If your ChatGPT workspace has native MCP Connectors (Business, Enterprise, or Pro plans), skip the Custom GPT path and use the Claude.ai connector flow — same setup, same URL.
