A PDF API for developers and AI agents. No template editor, no template IDs, no dashboard. One POST request, or one MCP tool call. Markdown comes with a stylesheet that makes agent-written documents look right by default. | built for | invoices · receipts · reports · agent output | | send | Markdown, HTML, or a public URL | | get back | PDF bytes, or a link that expires in an hour | Invoice 42 | Item | Price | |--------|--------| | Widget | $9.00 | | Item | Price | |---|---| | Widget | $9.00 | | Gadget | $24.00 | no signup needed, 10 seconds curl -X POST https://mintpdf.dev/v1/pdf \ -H "Content-Type: application/json" \ -d '{"markdown":" Invoice 42\n\n| Item | Price |\n|---|---|\n| Widget | $9.00 |\n| Gadget | $24.00 |","pageNumbers":true}' \ --output invoice.pdf → 200 application/pdf · one A4 page, table already styled want a link instead of bytes? add: "output": "url" → {"download url": "…", "expires at": "…"} one line in your MCP config "mintpdf": { "command": "npx", "args": "-y", "mintpdf-mcp" } or point straight at the hosted endpoint with mcp-remote: …railway.app/mcp | tools | generate pdf · pdf from url | | transport | streamable HTTP, stateless | | returns | download URL, 1h TTL | bash send content, not a template id $ curl -sS -X POST https://mintpdf.dev/v1/pdf \ -H 'Content-Type: application/json' \ -d '{"markdown":" Q3 report\n\nRevenue grew 12% .", "pageNumbers":true, "footerText":"Acme Ltd"}' \ -o report.pdf -D - HTTP/2 200 content-type: application/pdf x-ratelimit-remaining: 2 $ pdfinfo report.pdf | head -3 Pages: 3 Page size: 595 x 842 pts A4 File size: 166 kB prefer a link? add "output":"url" $ curl -sS …/v1/pdf -d '{"markdown":" Hi","output":"url"}' {"download url":"https://mintpdf.dev/f/…", "expires at":"…","size bytes":6751} ✓ the file is deleted an hour later One POST, or one MCP tool call from an agent. No template to design first, no template id to keep in sync with your code. Markdown gets a stylesheet that keeps code blocks and tables whole across page breaks and repeats table headers. Send HTML instead and your own CSS is used as-is. Stream the file straight into your response, or take a download URL valid for one hour. Nothing is stored afterwards. One email, one key, no card.
