Each image lands as an item filed in Canvas exports, a PDF as one document item there, with lineage to the pictures drawn and the canvas as provenance, and the same pixels rendered again come back as the item that already holds them. The answer names what was filed, with urls, and a picture it could not fetch in not_drawn; a cloud pdf over twelve pages is a job, and get_jobs names its item. inspect_canvas is for looking. Cloud processing per slide. ## OpenAPI ````yaml /openapi.json post /tools/render_canvas openapi: 3.1.0 info: title: Eversince API version: '1' description: >- Every Eversince tool as one POST call, plus the routes beside them: the tool list, account and keys, uploads, webhooks and models.
