Evidence claims:
- [sourced_fact] Page lists core routes (/ws, /models, /upload/image, /view, /system_stats), prompt and node routes (/prompt GET/POST, /object_info), history, queue, /interrupt, /free, userdata and users routes, plus WebSocket message types status, executing, progress, executed. · source: https://docs.comfy.org/development/comfyui-server/comms_routes
- [sourced_fact] POST /prompt validates the submitted graph and queues it, returning a prompt_id and number, or error and node_errors on validation failure; the page itself gives no JSON schema or example of the API-format workflow. · source: https://docs.comfy.org/development/comfyui-server/comms_routes
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
