Request

imagestring binary required

The image file to upload

overwritestring

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.

subfolderstring

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.

typestring

Upload type (defaults to "output"). Note: Accepted for ComfyUI API compatibility. Cloud stores all uploads as assets with tags rather than directory-based organization.

Response

Image uploaded successfully

namestring

Filename of the uploaded image

subfolderstring

Subfolder path where image was saved

typestring

Type of upload (e.g., "output")
