Automated generation of web API descriptions from usage data

A computer-implemented method for creating a web programming interface (API) description may include parsing an API usage dataset with a processor to identify a plurality of nodes in each of a plurality of uniform resource locators (URLs), and tagging path parameters for the plurality of nodes. Tagging the path parameters may include identifying, with the processor, which nodes are static parts of the URLs, and identifying, with the processor, which of the nodes are path parameters for the URLs. The method may further include aggregating, with the processor, a plurality of node types based on the tagged path parameters and the static parts of the URLs, and outputting, via the processor, an API description based on the aggregated plurality of node types.
