Read Canvas State
The authoring read: lossless DSL snapshot + short-id table + revision token.
Distinct from GET /v1/canvases/{id} (the design-to-code semantic read) —
this is the byte-identical agent snapshot the mutation verbs address.
Authorizations
API key from Settings > Developer > REST API
Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.
2026-04-12, 2026-05-01 "2026-05-01"
