You can generate OpenAPI specifications from captured traffic by running an extractor against captures.json or HAR files to analyze endpoints, parameters, authentication schemes, and data schemas, outputting a structured patterns.yaml and an OpenAPI file.

Yes, you can extract API patterns from HAR files automatically. The extractor analyzes HAR captures to infer request and response parameters, authentication modes, and endpoint dependencies, producing reusable API specifications and code skeletons.

Yes, you need Python to extract API patterns from network traffic. The extraction process requires Python and minimal external libraries to parse captured traffic and generate the structured patterns file containing endpoints, schemas, and authentication details.

Supported output formats when converting traffic captures to API documentation include YAML and JSON. The extractor generates an OpenAPI specification in yaml or json format along with a preliminary code skeleton for quick API engineering implementation.

The best way to discover endpoint dependencies from API traffic captures is using an automated pattern extractor. It analyzes the sequential flow within captures or HAR files to infer relationships between endpoints and outputs them in a structured patterns file.

A limitation when inferring authentication schemes from HAR files is that the extractor relies entirely on the data present in the capture. If authentication tokens or headers are missing from the recorded traffic, the generated OpenAPI specification will lack accurate authentication details.
