in plain english

00query is a desktop tool for looking up information about a company's online assets, using data from a service called 0.zone. It combines five kinds of lookups into one program: information systems and websites, mobile apps, domains, email addresses, and leaked source code or documents, so a user does not need to check each of these separately. The program has a graphical interface built with Python, and comes with prebuilt themes you can switch between, seventeen in total. Search results can be exported to Excel or CSV files for further use. The tool also supports an advanced search syntax with symbols for exact matching, containment, combining conditions with AND or OR, and grouping terms with parentheses, along with a built in guide explaining this syntax. One feature specifically looks for what the author calls suspected information systems, similar to a business directory listing. To use it, you either install the Python dependencies and run the program directly, or download a prebuilt Windows executable that requires no Python installation. Either way, before first use you need to register for an account with 0.zone to get an API key, which you then enter in the program's settings. The README notes that this API key comes with a daily limit on free queries, and warns that the packaged executable file may sometimes be flagged incorrectly by antivirus software, though the source code is available to review. The project lists three files as its core: the main GUI program, a local configuration file that is excluded from version control, and the Python dependency list. It credits the 0.zone service for providing the underlying data API and the ttkbootstrap library for its interface themes. The author is credited by a handle and links to a Bilibili channel and WeChat account for a full usage tutorial.
