API Request Fetcher is a lightweight Chrome add-on designed for developers, testers, and security researchers to streamline the process of inspecting and exporting HTTP headers and cookies. This tool allows users to set up listening rules for specific domain names, automatically extracting and formatting essential request parameters such as Authorization, Cookie, and Custom Headers. By eliminating the need to manually sift through numerous network requests in Chrome DevTools, it enhances productivity and efficiency in API debugging.

The add-on features one-click extraction of critical authentication information, allowing users to copy data in JSON format for easy integration into tools like Postman or cURL. With flexible configuration options, users can define custom listening domains and specify the fields they wish to capture, ensuring that only relevant data is retrieved. Additionally, API Request Fetcher operates entirely locally, prioritizing user privacy by not uploading any sensitive information.
