REST API Endpoint Generator

Scaffolds a complete, validated, well-documented REST API endpoint in any stack.

Best For

•Backend developers scaffolding a new endpoint who want validation, error handling, and docs generated together instead of piecemeal.
•Solo founders building an MVP API who need production-reasonable error responses without researching REST conventions from scratch.
•Teams writing API specs before implementation who want a consistent starting template across endpoints.

Prompt Template

Design and implement a REST API endpoint for [ENDPOINT PURPOSE, e.g. 'user authentication', 'product search', 'order creation']. Stack: [LANGUAGE/FRAMEWORK, Node.js/Express, Python/FastAPI, etc.]. Include: (1) the route definition with HTTP method and path, (2) request validation (required fields, types, constraints), (3) business logic with inline comments, (4) success response with example JSON (200/201), (5) error responses for: 400 bad request, 401 unauthorized, 404 not found, 500 server error, (6) one middleware function for authentication/logging if relevant. Follow RESTful conventions. Add JSDoc or docstring comments.

Pro Tip

Specify your existing auth middleware or error-handling pattern in the prompt, otherwise the model will invent its own convention that won't match the rest of your codebase.

Example Output

A sample of what this prompt produces once you fill in the placeholders.

For a 'product search' endpoint on Node.js/Express, the output defines GET /api/products/search with query param validation for 'q' and 'limit', a search handler with inline comments, a 200 response with a sample JSON array of products, 400/404/500 error bodies, and a logging middleware function, all with JSDoc comments.
