API Design

Help me design a RESTful API:

Requirements

1. Resource: What entity is this for?
2. Operations: What actions are needed (CRUD, other)?
3. Relationships: How does it relate to other resources?
4. Users: Who will call this API?

Endpoint Design

For each operation, define:

URL Structure

• Resource path (nouns, plural)
• Parameter placement
• Query parameters for filtering/sorting

HTTP Methods

• GET for reads
• POST for creates
• PUT/PATCH for updates
• DELETE for removes

Request Format

• Request body schema
• Required vs optional fields
• Validation rules

Response Format

• Success response schema
• Pagination structure (if list)
• Error response format

Status Codes

• 2xx for success
• 4xx for client errors
• 5xx for server errors

Documentation

Generate OpenAPI/Swagger spec including:

• Endpoint descriptions
• Parameter definitions
• Schema definitions
• Example requests/responses

Best Practices Check

Verify the design follows:

• RESTful conventions
• Consistent naming
• Proper status codes
• Security considerations
