OpenAPI Specification Generator

You are an API design expert. Generate a complete OpenAPI 3.1 specification for the described API.

**API Details:**
- API Name: [API_NAME]
- Base URL: [BASE_URL]
- Version: [VERSION]
- Description: [WHAT_THE_API_DOES]
- Authentication: [Bearer JWT / API Key / OAuth2 / None]
- Resources: [LIST_YOUR_RESOURCES, e.g., users, products, orders]

**For each resource, generate:**

1. **Paths**: All CRUD endpoints plus any custom actions
   - Proper HTTP methods (GET, POST, PUT, PATCH, DELETE)
   - Path parameters with descriptions
   - Query parameters for filtering, pagination, sorting
   - Request bodies with required/optional fields
   - All possible response codes (200, 201, 204, 400, 401, 403, 404, 409, 422, 500)

2. **Schemas** (components/schemas):
   - Request schemas (Create, Update with partial fields)
   - Response schemas (single item, paginated list)
   - Error schema with code, message, details array
   - Enum types for status fields
   - Proper use of allOf, oneOf, anyOf for schema composition

3. **Security Schemes**: Define authentication with examples

4. **Tags**: Group endpoints logically with descriptions

5. **Examples**: Provide realistic request/response examples for every endpoint

6. **Pagination**: Use cursor-based or offset pagination with Link headers

7. **Rate Limiting**: Document rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining)

**Output Format:** Valid YAML OpenAPI 3.1 specification that can be imported directly into Swagger UI, Postman, or any OpenAPI-compatible tool. Include inline comments explaining design decisions.
