FAQPage Schema
How do I generate OpenAPI specs from source code?

Generate API documentation from source code by running static analysis on your codebase to extract endpoints, parameters, and responses from docstrings and type hints. This process automatically converts your code structure into accurate OpenAPI documentation.

Can I automatically update API documentation when my code changes?

Yes, you can automatically update API documentation when code changes by running the static analysis tool against your updated codebase. It extracts new endpoints and parameters from docstrings and type hints to ensure your docs remain synchronized with the source code.

Does API documentation generation work with Python and JavaScript?

API documentation generation works with Python, JavaScript, and other programming languages by analyzing source code, docstrings, type hints, and comments. It extracts endpoints and parameters to produce comprehensive integration guides and SDK usage examples for these languages.

What is the best way to create endpoint docs and SDK examples from existing code?

The best way to create endpoint docs and SDK examples from existing code is using static analysis to parse docstrings, type hints, and comments. This approach automatically extracts endpoints, parameters, responses, and errors to generate structured integration tutorials without manual writing.

How does code-to-docs static analysis handle missing docstrings and comments?

Static analysis for code-to-docs generation relies on docstrings, type hints, and comments to extract endpoints and parameters. If these are missing or incomplete, the generated API documentation will lack detailed descriptions, requiring you to add code comments for comprehensive output.
