Is TheGuarantors - Chrome Extension safe?

Low risk

TheGuarantors - Chrome Extension sends building-list requests to theguarantors.com with a bundled API key.

When used on supported StreetEasy pages, the extension asks its background script to fetch building data from TheGuarantors. That request includes a hardcoded API key in the headers and retrieves building names, streets, and StreetEasy attributes for New York and New Jersey listings.
