REST API Spec Generator

Starting a new API resource means writing the same six routes every time: list all, fetch one, create, replace, partial update, and delete. Getting HTTP methods right and path pluralisation consistent is easy to rush when you are defining the fourth resource in a row. This generator handles the repetitive part. Enter a singular resource name — user, product, or order — and the generator returns all six endpoints with the correct HTTP methods, pluralised collection paths, per-item paths with :id, and a short description of each operation. The resource is lower-cased and pluralised by appending an s if it does not already end in one. Copy the list into your router or API design doc. Drop endpoints your resource does not expose and add request/response shapes and status codes as the next step.

Detailed instructions

  1. Enter the resource name, singular.
  2. Click Generate to produce the CRUD endpoints.
  3. Copy the list into your router or API docs.
  4. Add request and response details for each endpoint.

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 name pluralised in the path

REST convention treats a collection as a plural noun — /api/users represents all users and /api/users/:id a single one. The generator pluralises the resource name by appending an s if it does not already end in one.

what is the difference between PUT and PATCH

PUT replaces the entire resource with the payload you send, while PATCH updates only the fields you include. The generator lists both because many APIs support both; drop the one you do not need.

does it generate request bodies or response schemas

No. It outputs the method, path, and a one-line description for each endpoint. Add request and response shapes, status codes, and authentication rules as the next step.

what if my resource name already ends in s

The generator checks and skips adding another s, so orders stays orders. Review the result and adjust manually if the pluralisation is incorrect for an irregular noun.
