Overview

Generate professional API documentation that developers can use to integrate with your API, including endpoint specifications, authentication, request/response examples, and interactive documentation.

When to Use

• Documenting REST APIs
• Creating OpenAPI/Swagger specifications
• GraphQL API documentation
• SDK and client library docs
• API authentication guides
• Rate limiting documentation
• Webhook documentation
• API versioning guides

Quick Start

Minimal working example:

openapi: 3.0.3
info:
  title: E-Commerce API
  description: |
    Complete API for managing e-commerce operations including products,
    orders, customers, and payments.

    ## Authentication
    All endpoints require Bearer token authentication. Include your API key
    in the Authorization header: `Authorization: Bearer YOUR_API_KEY`

    ## Rate Limiting
    - 1000 requests per hour for authenticated users
    - 100 requests per hour for unauthenticated requests

    ## Pagination
    List endpoints return paginated results with `page` and `limit` parameters.
