Get a direct upload URL
Returns a sandbox-scoped authenticated URL for uploading a single file.
Upload with multipart POST using a file field, or stream raw bytes
with PUT to the returned URL.
The URL contains a short-lived file transfer token scoped to the target
sandbox path. The compatibility token field returns the same scoped
token for clients that still expect a separate token property.

Path Parameters
Sandbox ID (e.g. sb_a1b2c3d4)
Body
Sandbox path to target. Absolute paths may target valid sandbox locations such as /workspace, /data, /tmp, or /context where present. Relative paths resolve from the sandbox cwd when set, otherwise from the selected user's home when user is provided, otherwise from /workspace.
Optional sandbox user for relative-path resolution and ownership.
