PDF Generation in Python (FastAPI + DocuForge)

Introduction Python dominates backend development and data pipelines for good reason: its ecosystem is vast, its syntax is readable, and frameworks like FastAPI make building production-grade APIs remarkably straightforward. When those APIs need to produce PDFs -- invoices, reports, shipping labels, compliance documents -- most teams reach for libraries like ReportLab or WeasyPrint, then spend days wrestling with layout quirks and font rendering. DocuForge takes a different approach. Instead of generating PDFs locally, you send HTML (or a template reference) to the DocuForge API and get back a pixel-perfect PDF. The official Python SDK wraps this workflow with httpx for HTTP transport and Pydantic v2 for response validation, so everything feels native to a modern Python stack. In this tutorial you will build a FastAPI application with three PDF endpoints: one that converts raw HTML, one that uses a stored template, and one that streams a PDF file download directly to the browser.
