Quick Overview
Quick Overview This workflow triggers on new ImageKit uploads, downloads the image, uses OpenRouter (OpenAI GPT-4o) vision to run an NSFW check, and automatically unpublishes flagged assets in ImageKit so they are not served via your CDN. How it works Triggers when ImageKit emits a file.created event for a newly uploaded asset. Downloads the uploaded image from the ImageKit URL as binary data. Sends the image to OpenRouter using the OpenAI GPT-4o model to return a structured JSON verdict (is_nsfw, confidence, and reason). Checks the model verdict and, when is_nsfw is true, updates the ImageKit file to set it as unpublished. Ends without taking action when the image is not flagged. Setup Add ImageKit credentials for both the ImageKit trigger (webhook) and the ImageKit API operation used to unpublish files. Create an OpenRouter credential with access to the openai/gpt-4o model. In ImageKit, register the n8n webhook URL for file.created events and ensure new uploads default to published if you want this workflow to act as the gatekeeper.
