SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OpenAPI specifications often lag behind evolving APIs, causing documentation gaps and integration challenges.

Core Features & Use Cases

  • OpenAPI 3.1 structure scaffolding matching code and design inputs
  • Support for Design-First, Code-First, and Hybrid workflows
  • Templates for Complete API Spec, Python/FastAPI code-first, TypeScript/tsoa code-first, and validation & linting
  • SDK generation and publishing-ready documentation

Quick Start

Start by providing your API code or design artifacts and choose a workflow (Design-First or Code-First) to generate, validate, and publish an OpenAPI 3.1 specification.

FAQPage Schema
How do I generate an OpenAPI 3.1 specification from existing Python FastAPI code?

To generate an OpenAPI 3.1 specification from Python FastAPI code, use a code-first workflow template that automatically scaffolds and extracts API structures directly from your codebase into a complete spec.

What is the best way to validate API documentation against the OpenAPI 3.1 standard?

Validating API documentation against the OpenAPI 3.1 standard involves applying built-in linting templates to your specifications, ensuring consistent API contracts and compliance across design-first and code-first workflows.

Can I use TypeScript and tsoa for code-first OpenAPI spec generation?

Yes, you can use TypeScript and tsoa for code-first OpenAPI spec generation by applying specialized templates that scaffold OpenAPI 3.1 structures matching your TypeScript design artifacts and code inputs.

Does this approach support both design-first and code-first API documentation workflows?

Yes, this approach supports design-first, code-first, and hybrid workflows, allowing you to generate, validate, and publish OpenAPI 3.1 specifications regardless of whether you start from design artifacts or existing code.

How do I create a complete OpenAPI 3.1 spec scaffold from scratch?

You create a complete OpenAPI 3.1 spec scaffold from scratch by utilizing built-in templates that structure your initial design artifacts into a valid, publishing-ready API specification.

Why does my OpenAPI specification lag behind my evolving API codebase?

OpenAPI specifications lag behind evolving APIs when generated manually, but automating spec generation from code and validation patterns ensures documentation stays synchronized and prevents integration challenges.
