1. Complete API setup above (Custom GPT, Google AI Studio function calling, or MCP - regular chat apps cannot call the API).
2. After your connector + key are configured, try:

Create a personal guide called Shopping preferences on my Guides account. Use what you know about me plus anything I add here. Sections: clothing sizes, colors and style, brands I like, my town for local shopping. Create via the GDF API as a draft and tell me the slug.

1. Review the draft in Studio, edit, publish when ready.
2. Later: GET /api/gdf/v1/guides/shopping-preferences before recommending products.
