SciDraw AI REST API: Text-to-Scientific Illustration in n8n

Turn your text prompts into scientific illustrations inside n8n—automatically

With the SciDraw AI REST API: Text-to-Scientific Illustration in n8n workflow, you can submit a prompt to SciDraw AI, wait for the generation job to finish, and then download the resulting scientific image directly into your n8n workflow as binary data.

What this workflow does

• Runs on manual execution in n8n (you start it when you need an illustration).
• Sets generation parameters such as your illustration prompt, aspect ratio, resolution, image count, and a unique idempotency request ID.
• Creates a SciDraw generation job by sending a POST request to the SciDraw AI REST API.
• Waits and polls for completion: it checks job status, then waits 5 seconds and continues polling until the job reaches a terminal state (success, failed, or canceled).
• Stops on errors using “Stop and Error” if SciDraw reports the job as failed or canceled.
• Downloads the first generated image when the job succeeds and stores it in n8n as binary data.

Use cases

• Create scientific-style figures for reports, proposals, and scientific documentation directly from descriptions.
• Generate consistent visuals in a content pipeline, using prompts that your team maintains in n8n.
• Provide SaaS users with on-demand diagram assets by triggering the workflow from your own process.

Technical details

• SciDraw AI REST API (job creation + job status polling + image download)
• Requires a SciDraw API key with access for images:generate and jobs:read, stored as an n8n HTTP Header Auth credential (Authorization: Bearer <key>).
• n8n nodes include: HTTP Request, Wait, If, Edit Fields, and Stop and Error (plus supporting nodes).

Tip: Update the prompt, aspect ratio, resolution, and count before running to match your scientific illustration requirements.
