POST /api/markdown-to-pdf · $0.01 per call (USDC on Base or Solana, x402)

Render Markdown into a clean PDF (headings, paragraphs, bold/italic/links, nested lists, code blocks, blockquotes, simple tables, page numbers, PDF bookmarks from H1-H3, internal #anchor links, embedded Unicode font: Latin, Greek, Cyrillic, €). POST JSON { markdown, title?, paper?: "A4" | "Letter" } (max 200k characters), get application/pdf back. For hosted agents that must deliver a report, a memo or an invoice as a file. Nothing stored.

Round trip: doc to Markdown, edit the Markdown, then back to PDF.
