# Register a file in a space and get a presigned upload URL

POST https://api.cloudraker.com/spaces/{spaceId}/files
Content-Type: application/json

Reserves a file metadata record in the space and returns \{ id, uploadUrl, uploadExpiresAt, file }. `uploadUrl` is a secure PUT URL valid for 15 minutes (see `uploadExpiresAt`, ISO 8601). Two-step upload: PUT the raw file bytes to `uploadUrl` with a `Content-Type` request header EXACTLY equal to the `mimeType` you sent at create (a mismatch rejects the PUT), then poll `getFile` until `status` reaches a terminal value — `stored` (uploaded, no processing requested), `processed` (processing succeeded), or `failed` (see `processingError`); `waiting`/`processing` mean keep polling. Request body: `fileName` (required), `mimeType` (required, drives both the record and the required PUT Content-Type), `size` (bytes, optional), optional `processingKind` — one of doc-simple | doc-ocr | doc-auto | audio-transcribe | audio-transcribe-and-diarize — selecting how the stored file is post-processed; `indexVectors` and `indexOntology` (both default true) are opt-out booleans for semantic and ontology indexing — both are FORCED false for a desk (`me:<userId>`) space, whose files are never indexed. `parentType`/`parentId` in the body are ignored: the API forces the parent to this :spaceId. Authorization: requires `space:contribute` on :spaceId (missing permission → 403; org admins bypass). An invalid body returns 422.

## Authentication

- `Authorization` header (bearer token, required)

## Request

### Path parameters

- `spaceId` (string, required)

### Body (application/json)

- `fileName` (string, required)
- `mimeType` (string, required) — Drives both the record and the required upload `Content-Type`.
- `size` (integer, optional) — Size in bytes.
- `processingKind` (enum, optional) — How the stored file is post-processed. Omit for automatic selection by mime.
  - Allowed values: `doc-simple`, `doc-ocr`, `doc-auto`, `audio-transcribe`, `audio-transcribe-and-diarize`
- `indexVectors` (boolean, optional, default: true) — Semantic indexing.
- `indexOntology` (boolean, optional, default: true) — Knowledge-graph indexing.

## Response

### 201

File record created, with its presigned upload URL.

- `id` (string, required)
- `uploadUrl` (string, required) — Presigned upload URL, valid 15 minutes. PUT the raw bytes there with a `Content-Type` header EXACTLY equal to the `mimeType` sent at create.
- `uploadExpiresAt` (datetime, required)
- `file` (object, required)
  - `id` (string, required)
  - `fileName` (string, required)
  - `parentType` (string, required)
  - `parentId` (string, required)
  - `mimeType` (string, required)
  - `size` (double, required, nullable) — Size in bytes, null until stored.
  - `status` (enum, required) — Terminal values are `stored` (uploaded, no processing requested), `processed` and `failed`; `waiting` and `processing` mean keep polling.
    - Allowed values: `waiting`, `stored`, `processing`, `processed`, `failed`
  - `processingKind` (enum, required, nullable)
    - Allowed values: `doc-simple`, `doc-ocr`, `doc-auto`, `audio-transcribe`, `audio-transcribe-and-diarize`
  - `createdAt` (datetime, required)
  - `processingError` (string, optional)
  - `parentFileId` (string, optional) — Source file this one was generated from (e.g. a redacted or signed copy).
  - `artifacts` (list of string, optional) — Parsing byproducts present, e.g. `structured`, `transcript`.
  - `indexVectors` (boolean, optional)
  - `indexOntology` (boolean, optional)
  - `storedAt` (datetime, optional)
  - `processedAt` (datetime, optional)
  - `urls` (object, optional) — Minted download links, each valid ~1 hour. Present on single-file reads only — list responses mint none.
    - `file` (string, optional) — The stored original.
    - `processedJson` (string, optional) — Structured/grounded JSON.
    - `processedMd` (string, optional) — Extracted markdown.
    - `previewPdf` (string, optional)
