WorldCanvas Docs

WorldCanvas is a single, permanently growing collaborative canvas. Anyone can claim a rectangular region of pixel space (a “Cell”), publish artwork into it, and keep that Cell, and its full history, forever. Below are direct links to WorldCanvas’s actual public governance documents, each an exact PDF replica of the original.

Public API

These endpoints need no authentication and return JSON (except the profile page, which is HTML). This is a Phase I foundation, so there is no versioning, rate limiting, or API keys yet.

GET	/api/cells	List every Cell on the canvas.
GET	/api/cells/{wcid}	Look up a single Cell by its permanent WCID.
GET	/api/cells/{wcid}/history	Full ownership history for a Cell (claim, sales).
GET	/api/artwork/{versionId}	Fetch one Artwork image by its version id.
GET	/api/collections/{id}	List a Collection's member Cells.
GET	/api/founders	The public Founder Registry.
GET	/u/{displayName}	A contributor's public profile page (HTML, not JSON).
