Abstract: A system generates a number of uniform resource locators as application program interfaces in an intelligent way based on live traffic. Live traffic between a server and multiple users is monitored and intercepted and forwarded to a remote server that processes the traffic. Traffic URLs are processed to build a digital data structure that represents nodes or portions within each URL. For URLs having different nodes at the same hierarchical level that have the same type, the present system may replace those different nodes with a representative node. The representative node replaces the nodes at the same hierarchical level having the same type, but having different values.
