I will create swagger api documentation, openapi spec and postman collection

Hi, I write Swagger / OpenAPI documentation for APIs that never got proper docs.

You probably know the situation: the API works, but the docs are a half-finished README, an old Swagger 2.0 file or a Postman collection only one person understands. New devs and clients keep asking how an endpoint works.

Send me whatever you have, even just your route files (Express, NestJS, Next.js, FastAPI). I'll give you back:

- A Swagger / OpenAPI 3.0.3 spec in YAML and JSON

- An HTML docs page (Swagger UI) you open with a double-click, no server needed

- A clean Postman collection with folders, a baseUrl variable and example requests

- On Premium, a typed TypeScript SDK and an MCP server so Claude or Cursor can call your API

Before I deliver, I validate the spec against the official OpenAPI schema and check that every route from your code or docs is in it. If one is missing, I fix it first.

One honest note: I document what's in your code and docs. If you want me to check it against your live API, add the sandbox extra.

Not sure which package fits? Message me, I usually answer within the hour.
