Read Canvas Edit
Read the compact Main Edit, exact time values, and named runtime capability diagnostics.
validation.export_readiness reports whether an mp4 export of this
timeline would pass the export planner’s plan-level gates
({exportable, reason?, detail?, work_units?, work_unit_budget, coverage: "plan"}): source availability and authorization, export
capability audit, and the composited work budget — the same ladder the
export lane enforces, priced with the same hydrated media metadata, so
valid alone is never mistaken for “exportable”. Render-time fidelity
refusals (artwork a page cannot render faithfully) are only discoverable by
rendering; they decline at export with the offending entity named.

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.
