AI assisted API development

I am looking for a real professional interested in Rapid Application Development.

At https://github.com/allenheltondev/api-spec-quickstart - and the linked blog post...Seem to be some pretty simple instructions for developing an API for a dataset, starting from JSON.

My thinking is that https://mockaroo.com/ and others make it easy to visually design database tables, and output the same mocked data in CSV, JSON, SQL, and Excel formats.

Am interested in the tricks to develop a Postman API server.

I would like to get the the point of building the web form described in "If I were to turn this into a “real thing” I’d create a webpage and do the entire generation asynchronously. You’d have a page where you input your schema and you’d receive an email with your API spec and url to the mock server when it completes or just a simple in-app notification and screen re-render. This way you can control everything from a single location. The backend would also need to change a bit. I’d still probably use the same collection, but call it via Newman in a Lambda function as part of a Step Function workflow."

I am not certain of the value of the above exercise, though, as generic AIs like Gemini does fine schema generation and data mocking, 

https://g.co/gemini/share/62f74b03d0e0 , and there are no-code tools that generate an API for the database automatically.

"Now that I have a solid way to make an Open API spec and get a functioning mock server, I’d like to take it a step further and generate an SDK to call it. Many developers use SDKs to communicate with their backend services, and tools like OpenAPI Generator, https://openapi-generator.tech/docs/generators,  enable them to do so without having to manually build them. OpenAPI Generator will take an API spec and compile it down into an SDK in the language of your choice, including front-end compatible languages like typescript-fetch."

So, this process seems to be the quickest way to build working infrastructure for a dev project, and maybe the clients and doc, as well.   Since this process starts from JSON, we'd just have to ask the AI to provide the mock data in JSON as well.

I am looking for professionals for my upcoming RAD project, so collecting thoughts and looking for thinkers (and doers).
