请求体
The image file to upload
Whether to overwrite existing file (true/false). Note: Accepted for ComfyUI API compatibility but effectively ignored in cloud. Cloud uses content-addressed storage (hash-based deduplication), so identical content always maps to the same hash. Re-uploading the same content is a no-op.
Optional subfolder path. Note: Accepted for ComfyUI API compatibility but ignored for storage. Cloud stores assets by hash only. The subfolder is returned in the response for client-side organization but is not used for server-side storage paths.
Upload type (defaults to "output"). Note: Accepted for ComfyUI API compatibility. Cloud stores all uploads as assets with tags rather than directory-based organization.
