Why Use the API Documentation Generator
- OpenAPI 3.0 output — compatible with Swagger UI, ReDoc, Postman, and SDK generators
- Multiple formats — OpenAPI YAML/JSON, Markdown, and standalone HTML
- Code examples — generates curl, JavaScript, and Python examples automatically
- Error documentation — templates for consistent error response documentation
- Authentication patterns — API key, Bearer token, OAuth 2.0 documented correctly
- No manual writing — generate a complete documentation skeleton from endpoint definitions

## Authentication
This API uses Bearer token authentication. Include the token in the
Authorization header of every request:
```
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
```
### Obtaining a Token
POST /auth/token
Request:
```json
{
"email": "user@example.com",
"password": "yourpassword"
}
```
Response:
```json
{
"accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
"expiresIn": 3600,
"tokenType": "Bearer"
}
```
Tokens expire after 1 hour. Use the refresh token endpoint to
obtain a new access token without re-authenticating.
