Convert Markdown into a branded PDF with table of contents using PDFMint

## Convert Markdown into a branded PDF with a table of contents Who it is for Anyone holding Markdown — an AI agent's answer, release notes, a knowledge-base page, a report written in an editor — who needs a finished, branded PDF back in the same request. No headless browser to run, no template editor to log into. How it works 1. Receive the Markdown document takes a POST with markdown, title and an optional author. 2. Set your document branding is the one node you edit: brand name, accent colour, page format, whether a table of contents is added, and an optional watermark such as DRAFT. 3. Check the request is usable turns an empty payload into a readable 422 before anything is rendered. 4. Check remaining quota asks PDFMint how many credits are left. The usage operation costs nothing. 5. Build the cover, contents and body does all the work in one place: it numbers every ## and ### heading, builds a contents list from exactly those numbers so the two cannot drift apart, skips headings inside fenced code blocks, counts the words, estimates the reading time, and assembles a cover block. It also derives the running header and the CSS from your accent colour. 6. Render the Markdown as PDF sends the assembled Markdown to PDFMint with your header, page numbers and styling. 7. Did the render succeed? decides which answer the caller gets, because the render node is set to continue on failure. 8. Return the PDF answers the POST with the file itself; Return the error as JSON answers with a status and a reason, so a caller never hangs.
