# Upload Material

`POST /api/app-auto-gtm/outreach/materials`

Upload a file into ONE project's library. Moderated the same way regardless.

``project_id`` is required (T-1069: materials are strictly project-scoped —
the uploading page always knows its project). ``ephemeral=true`` = a one-off
file attached inline from the inbox composer for a single reply — it does
NOT enter the project's materials library and is not AI-described.
``ephemeral=false`` (default) = a curated library material (``description``
is a note read by the autopilot agent; AI-drafted if blank).
