binaco/DarkGPT ? reverse-engineered prompt

Build me a simple Python tool that works like an AI assistant for OSINT searches. I want to be able to run it from the terminal, enter a name, email, username, or similar query, and get back clear, easy to read results from leaked database lookups through the Dehashed API. It should read the API key from a local .env file, handle errors nicely, and keep the output organized so it’s useful for quick investigation work.

Make it easy to install with the dependencies listed, and have a main script I can run right away to start using it. If you need to check the latest docs for the API or any library behavior, look them up online. Also please keep the interface simple and practical, since I want something that feels like a lightweight assistant I can use from the command line without extra setup.
