la-deep-web/Phoneinfoga ? reverse-engineered prompt

Build me a Python command line tool that lets me look up phone numbers and gather basic public info about them.

I want to be able to enter one number or a whole text file of numbers, and have it check whether the number looks valid, then identify things like country, carrier, and line type. It should support common international number formats, and if possible let me scan with different public sources so I can get better results.

It would be great if there’s an optional OSINT mode that searches public web sources for footprints of a number, and a way to use a custom format for searches so results are more accurate. Please make it save results to a file when I want, and handle multiple numbers in one run.

If the tool needs online docs or current APIs to work well, look them up. Keep it simple to run from the terminal and make the output easy to read.
