# The ComfyUI repository ships openapi.yaml: can I generate a client from it for my local server, or does it describe something else?

openapi.yaml at the pin is a union spec that describes more than the local server.py. Of its 79 operations, 20 match a server.py decorator; 59 do not (assets, workflows, settings, billing, tasks, /health for a GKE ingress, etc.). It documents authenticated, cloud-style semantics (402/403/429 statuses, ApiKeyAuth/BearerAuth, 'authenticated user' scoping) and omits client_id and prompt_id from PromptRequest, which the local /prompt reads and the official examples send. It also says /api/interrupt cannot target a job, but the local handler accepts a prompt_id. A generated client should be treated as a draft: verify each call against server.py and prefer /api/jobs over the deprecated history routes only where the local server implements them.

Curator qualifications: Verified: the shipped spec is a hosted/union spec, not a contract for the local server. Spec-vs-handler conflicts (interrupt targeting, auth) are genuine. The 20/59/8 overlap counts are producer regex synthesis; curator confirmed 66 paths and the 79 operation figure as printed, not the overlap split.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
