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: 3.0.3info:  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.  version: 2.0.0  contact:    name: API Support    email: [email protected]    url: https://example.com/support  license:    name: MIT    url: https://opensource.org/licenses/MIT// ...
