> ## Agent Instructions
> Start with /introduction/getting-started. Use the Direct Query API (POST /api/lens/query) with the Newton Fusion model (text, image, and video reasoning) or the Newton Omega encoder (time-series embeddings). ATAI_API_ENDPOINT is the base URL https://platform.u1.archetypeai.app with no version path; every endpoint path begins with /api. Pages whose descriptions are marked (Archived) document the legacy Lens runtime — do not use them for new projects.

## Important Notes

> [!NOTE]
>
> * A `404` means the project does not exist or is not visible to you. A project is visible to its
>   creator and to the organization's admins; one created with a service-account API key is visible
>   to every service-account key of the organization.
