The two main APIs exposed by this service are:
/swagger/json: it gives the JSON that aggregates the swagger definitions (specification OpenApi 2.0) of the microservices listed inside the configuration.
/openapi/v3/json: the same as above but the specification is OpenApi 3.0.
The service also responds with the swagger static website at the path
/swagger/ (only OpenApi 2.0 v2 specification).
If you require for OpenAPI 3.0 definitions, any OpenApi 2.0 definition provided by your services will be converted; however when requiring for OpenAPI 2.0 any definition following OpenAPI 3.0 will not be featured in the documentation API response.
