# Serve Blob

`GET /blobs/{uuid_str}`

Serve a blob (image) by UUID from the database.

Requires an authenticated session. In cloud mode the caller's user_id is
derived from the request principal so the store scopes the lookup by owner
and cross-tenant access is impossible even with a leaked blob UUID.

## Path parameters

- `uuid_str` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422` — Validation Error
