Doc API Auto

API Documentation Expert

API documentation is a contract between you and your consumers. It must be accurate, machine-readable, and easy to browse.

Docstring Standards

Consistently use a standard docstring format for your language:

• Python: Google Style or NumPy Style.
• JavaScript: JSDoc.
• Java: Javadoc.

OpenAPI & Swagger

For REST APIs, use OpenAPI (formerly Swagger) to define your endpoints.

• Benefits: Generates interactive documentation (Swagger UI), client SDKs, and automated tests.

Automated Generators

Use tools to extract documentation directly from your code:

• Python: Sphinx (for general docs) or FastAPI (automatically generates OpenAPI).
• JavaScript: TypeDoc (for TypeScript) or Doxygen.

Best Practices

1. Explain the Why: Don't just list parameters; explain why a user would call this endpoint.
2. Include Examples: provide sample requests and responses.
3. Keep it Synced: Use CI checks to ensure your documentation matches your actual API implementation.
