# Download a file from a project

`GET /api/v1/file/download/{ownerId}/{projectId}/{fileName}`

## Request

- Base URL: `https://davinci-app.com`
- URL: `https://davinci-app.com/api/v1/file/download/{ownerId}/{projectId}/{fileName}`
- Auth: HTTP bearer

Streams a file from the machine holding your project.

Send this to `dataPlane.url` with `Authorization: Bearer {dataPlane.token}`.
Prefer this over the control-plane `downloadProjectFile` for large files: the
bytes travel directly rather than through the API server, with a 30-minute
window rather than 15.

A file belonging to a different project is served only when your project has
an active include referencing it — the same rule the editor follows.

## Response `200`

File bytes.

## Other responses

- `401`: The grant is missing, unknown, expired, or revoked. These are one response so a rejected request cannot be used to learn which grants exist. Refresh the session to get a new grant, or create a new session if that also fails.
- `403`: The grant does not carry `documents:read`, or the file belongs to another project with no active include referencing it.
- `404`: No such file.
- `409`: The project moved to another machine. Error code is `PROJECT_MOVED`. Retry the request: the next one resolves to the machine holding it now, at the same URL.
- `429`: Request rate exceeded, either globally or for this key.
- `500`: Unexpected server error.
