# Api related artifacts

## Prometheus metrics
Prometheus metrics are exposed for all api endpoints automatically at the standard `/metrics` endpoint. (http://localhost:8080/metrics) 

## Swagger API documentation 
Automatic API docs are generated and exposed for all routes at http://localhost:8080/swagger/index.html when the api server is running. 

## Logging 
Structured logging is built into all API routes automatically.

So for example here is a what a few API hits on queryService look like in the logs when using text  (as opposed to json) 

```bash
