# Get Assistant Build Plan

`GET /api/v1/assistant/chats/{chat_id}/build-plan`

## Request

- Base URL: `https://api.netter.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.netter.ai/api/v1/assistant/chats/{chat_id}/build-plan`
- Auth: none declared

Return the chat's live (non-terminal) build plan, or 404.

Authorization reuses `load_owned_assistant_chat` — the SAME check
`/message` and `/refine` share — rather than a new ownership check on
this route. That collapses the same three non-owner-reachable refusals
(absent / cross-tenant / suppressed, wrong chat type, not-yours) into the
identical `404 {"detail": "Chat not found"}` this surface's siblings
answer. When the chat IS the caller's own but carries no live plan, the
response is the SAME body — "no plan" and "not your chat" must stay
indistinguishable to a non-owner probing for chat existence.
