REST API Spec Generator

Used by developers, writers, and creators worldwide.

A REST API spec generator produces the standard set of CRUD endpoints for a resource, following REST naming conventions, so you can scaffold or document an API in seconds. Enter a resource name like user, product, or order and it returns the six endpoints you almost always need: list, fetch one, create, replace, partial update, and delete — each with the correct HTTP method and a conventional, pluralised path. Backend developers use it to plan a new API, keep route naming consistent across resources, and document endpoints for teammates. The resource is pluralised for collection paths and per-item routes include an :id parameter, matching the patterns most REST style guides recommend. Copy the list into your router, API docs, or a design doc, then add the request and response details specific to your resource. It is a fast, consistent starting point for RESTful routing.

Use Cases

  • •Scaffolding CRUD routes for a new API resource
  • •Keeping endpoint naming consistent across resources
  • •Documenting a REST API for teammates
  • •Planning routes during API design
  • •Teaching RESTful URL and HTTP method conventions

Tips

  • →Use a singular resource name — the tool pluralises collection paths.
  • →Drop any endpoint your resource does not need, such as PUT.
  • →Keep the same pattern across resources for a predictable API.
  • →Document status codes and payloads alongside each route.

FAQ

why is the resource pluralised in the path

REST convention uses plural nouns for collections, so /api/users represents all users and /api/users/:id a single one. This reads naturally and keeps URLs predictable, which is why the generator pluralises the resource for you.

what is the difference between put and patch

PUT replaces an entire resource with the payload you send, while PATCH updates only the fields you include. Many APIs support both, so the generator lists each; choose the one that matches how your clients update data.

does it generate request and response bodies

No. It outputs the route, method, and purpose so you have a consistent skeleton. Add the request payloads, response shapes, status codes, and authentication rules specific to your resource as the next step.
