Rest application programming interface route modeling

A computer program product, the computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:

• observe a plurality of uniform resource locators (URLs);
• parse a URL path of each of the URLs into path segments;
• create a tree structure, the tree structure having a plurality of nodes, each node representing a particular path segment of the path segments;
• determine a confidence factor for a first path in the tree structure using a decay function, the first path having an end node;
• and
• compact sibling nodes of the nodes into a compacted node in response to a number of the sibling nodes exceeding a variance threshold.

A system comprising:

• a processor, a computer readable memory, and a computer readable storage medium;
• program instructions to observe a plurality of uniform resource locators (URLs);
• program instructions to parse a URL path of each of the URLs into path segments;
• program instructions to create a tree structure, the tree structure having a plurality of nodes, each node representing a particular path segment of the path segments;
• program instructions to determine a confidence factor for a first path in the tree structure using a decay function, the first path having an end node;
• and
• program instructions to compact sibling nodes of the nodes into a compacted node in response to a number of the sibling nodes exceeding a variance threshold,
• wherein the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory.
