MelissaData/MelissaCloudAPI-OpenAPI-Specifications ? reverse-engineered prompt

Build me a simple website for the Melissa Cloud APIs OpenAPI specs so I can browse all the API docs locally and see each endpoint, inputs, and responses in one place.

I want a clean landing page that lists the available APIs like address verification, email, phone, name, IP, property, and the other Melissa cloud services, with links to open each spec and read the documentation. It should be easy to run on my machine, start on port 4000 by default, and let me change the port if I want.

Please make it feel like a straightforward docs viewer, with clear navigation, search or quick browsing if that fits, and a helpful note that a Melissa license key is needed to actually use the cloud APIs. If anything is unclear, look up the current docs online and match the existing Melissa style as closely as possible.
