Docling on Vercel

PDF convert jobs

The Next.js API stores the PDF in Vercel Blob, writes a job row in Neon, and starts a Workflow. Modal runs Docling and writes a Markdown file. Every API call needs the API secret. Poll the job ID until the download link is ready. Enter the same API secret later to list the jobs that this secret submitted.

Convert PDF to Markdown

Enter the API secret, then upload a digital PDF. The form posts the file and the secret in the body. A server action adds the Authorization header and calls the jobs API. Max 30 pages and 20 MB. OCR is off. You can also list jobs that this API secret submitted before.
