Automatically generating service documentation based on actual usage

A computer-implemented method performed by a computer system to automatically generate service documenting based on usage of a web service, the computer-implemented method comprising:

• capturing network traffic including actual requests to a service endpoint of the web service and actual responses from the service endpoint of the web service;
• analyzing captured network traffic to determine one or more operations that are available at the service endpoint, input arguments that are accepted by the service endpoint, and output arguments that are provided by the service endpoint;
• and
• automatically generating service documentation for the web service based on the one or more operations, the input arguments, and the output arguments.

A computer-readable storage medium storing computer-executable instructions that, when executed by a computer system, cause the computer system to implement:

• a network traffic capturer configured to capture actual requests to a service endpoint of a web service and capture actual responses from the service endpoint of the web service;
• a machine learning component configured to analyze captured network traffic and generate metadata that identifies one or more operations that are available at the service endpoint, input arguments that are accepted by the service endpoint, and output arguments that are provided by the service endpoint;
• and
• a service documentation generator configured to automatically generate service documentation for the web service based on the metadata.
