Discover Hidden Website API Endpoints Using Regex and AI

* https://www.sofaconcerts.org (**Knockout.js framework**). A music booking platform and starting point for this workflow. The **Google AI Studio** model helped define **most relevant endpoints** for automating booking communication between the platform and Slack: login, cookie session extension, fetching full event details, event ID and full dialog history endpoints. One endpoint for sending messages back to the platform as well as a detailed request format had to be explored using the **Network Tab in the Dev Tools** console.

* https://bandcamp.com (**Knockout.js framework**). Found **20+ API endpoints**, some working without authentication, e.g. https://bandcamp.com/api/salesfeed/1/get_initial. **Warning:** in this example, due to inconsistent model results, had to manually upload LLM analysis results before sending them to the **Agent**. 

* https://www.otto.de (backend is written in **Rust**, frontend is likely custom). Discovered **search autocomplete API endpoint** that allows exploration of product categories and specific items sold on the platform. 

* https://www.airbnb.com (complex **React**-based architecture). Found over **500** URL strings with dozens of potential API endpoints. The workflow makes it much faster to understand the sophisticated structure of the platform by analyzing the code of JS files.   

* https://www.jameda.de (**FOSJsRoutingBundle in Symfony**). Found several **ajax endpoints** for general information on specific doctors and their available time slots, e.g. https://www.jameda.de/ajax/doctor/slots-from-nearest-day/392937. To learn how to make requests, review the JS file + page source code for the required ID values. E.g. 327423 in the example URL is the code for a specific doctor.

* https://www.espn.co.uk (**jQuery/Bootstrap** with **Node.js** components). Identified over **300** URL strings, some matching API endpoints listed on **GitHub:** https://gist.github.com/akeaswaran/b48b02f1c94f873c6655e7129910fc3b. LLM analysis revealed several fan API endpoints.
