I have a similar need but for the FHIR[1] spec, which has its own way of describing RESTful http endpoints that serve FHIR data. I was looking into how this works for inspiration, and it seems like the work of inferring the OpenAPI definition from recorded requests/responses is handled by the har-to-openapi nodejs library [2]. Is this by the same team? If not, kudos for packaging this up in a proxy -- seems like a useful interface into that library. 1. https://www.hl7.org/fhir/ 2. https://github.com/jonluca/har-to-openapi

Genson-js is used to merge JSON Schema objects. Essentially there are 5 schemas that we care about in each request - request bodies, request headers, response bodies, response headers, and query parameters. Each endpoint (which may or may not be parameterised) has only one schema for each of these values. The idea for a crawler is a good one. The core logic that handles spec generation is decoupled from everything else, so it can be extracted into its own library. But there are approaches that exist for this already, such as har-to-openapi. https://github.com/jonluca/har-to-openapi
