Introduction

doclinth turns structured data into pixel-perfect PDFs (invoices, receipts, statements) from a single API call. You design a template once, then POST a small JSON payload and get back a finished PDF in about two seconds.

How it works

1. Author a template. Describe what you want in plain English and let AI generate the HTML/CSS, or start from a built-in starter and tweak it.
2. Generate deterministically. Send your data to POST /v1/generate. The generation path never calls an AI model, so output is fast and identical every time.

Next steps

• Quickstart: first PDF in under 5 minutes
• Authentication
• Generate a PDF: the API reference
• Template syntax
• Data contracts: every template is a typed API
• Document tests: break the layout before your customers do
