API Traffic Analyzer is a Chrome extension designed to enhance the efficiency of API documentation by capturing API traffic in real time. This tool works silently in the background as users interact with web applications, automatically detecting various API requests and responses, including REST and GraphQL calls. It translates the captured data into a structured and readable format, making it easier for developers and security teams to access and understand API endpoints, query parameters, and data structures.

One of the standout features of API Traffic Analyzer is its ability to uncover undocumented API endpoints—often referred to as Shadow or Zombie APIs—providing standard-compliant documentation on the fly. Furthermore, users can seamlessly export the captured traffic and generated documentation to the ApyGuard platform with a single click, facilitating comprehensive security testing and behavior profiling without complicated configurations.
