Canvas

List the project's canvas designs, newest first (with their thumbnails)

POST /services/canvas/v1/canvas/design/all Auth

Create a design: blank, or with nodes. A preset sets the size

POST /services/canvas/v1/canvas/design/create Auth

One design with its nodes. For the editor its images come back as data URLs (inline, the default); inline=0 gives URLs a browser loads

POST /services/canvas/v1/canvas/design/get Auth

Save a design from the editor: its nodes (images move to the media library), title, size and a small preview. Every field is optional

POST /services/canvas/v1/canvas/design/save Auth

Delete designs (their images stay in the media library)

POST /services/canvas/v1/canvas/design/delete Auth

Duplicate designs (the copies use the same media library images)

POST /services/canvas/v1/canvas/design/duplicate Auth

Rename a design (its id, the folder name, stays)

POST /services/canvas/v1/canvas/design/rename Auth

Save the rendered design (a PNG, JPEG or WebP data URL from the editor) in the media library, labelled "canvas". A design made from a media item becomes an edited copy of it

POST /services/canvas/v1/canvas/design/export-media Auth

A new design around a media library image ("Edit in Canvas"): the artboard has the image's size and the image fills it

POST /services/canvas/v1/canvas/design/from-media Auth

An image for the canvas as a data URL: a media library item of this project (media_id or its URL) or a theme photo. Any other URL is refused: the server fetches nothing it is handed

POST /services/canvas/v1/canvas/image/fetch Auth

Formats (sizes), layouts and icons, with the project's brand colors

POST /services/canvas/v1/canvas/templates/catalog Auth

The nodes of a layout at a size, filled with the project's brand: the editor's template previews and "apply to this design". Nothing is saved

POST /services/canvas/v1/canvas/templates/render Auth

Designs from a layout, one per preset, saved in one set

POST /services/canvas/v1/canvas/templates/create Auth

A QR code as layers (a light square and a vector path) for a link or text, to add to a design. Nothing is saved

POST /services/canvas/v1/canvas/qr Auth

Remove background from a canvas image (AI worker or solid-bg MVP)

POST /services/canvas/v1/canvas/image/remove-background Auth
