FAQPage Schema

How do I generate API documentation from source code?▼

Generate API documentation from source code by analyzing REST, GraphQL, and WebSocket APIs to extract endpoint details, request/response schemas, parameters, authentication requirements, and usage guidelines. This produces developer-friendly reference materials and OpenAPI/Swagger specifications automatically.

Can I create an OpenAPI or Swagger specification from my existing codebase?▼

Create OpenAPI or Swagger specifications from an existing codebase by analyzing API endpoints, HTTP methods, and parameters directly from source code. This generates up-to-date specification files alongside example code snippets and usage notes for evolving APIs.

Does API documentation generation work for GraphQL and WebSocket APIs?▼

API documentation generation works for GraphQL and WebSocket APIs, as well as REST. It analyzes source code to extract endpoint details, request and response schemas, authentication requirements, and error handling for each protocol type.

What's the best way to keep API docs updated for evolving APIs?▼

Keep API docs updated for evolving APIs by generating documentation directly from source code. This ensures consistency and reduces manual writing effort by automatically extracting current endpoint details, schemas, and versioning information into OpenAPI specifications.

How does automated code analysis extract API endpoint details?▼

Automated code analysis extracts API endpoint details by parsing source code to identify HTTP methods, parameters, authentication requirements, and error handling. It generates corresponding request and response schemas, examples, and usage guidelines for developer onboarding.

Do I need existing code annotations to generate API reference materials?▼

You do not need existing code annotations to generate API reference materials. This skill analyzes the source code structure directly to produce endpoint details, authentication requirements, error handling documentation, and example code snippets automatically.
