 If you wish to make sure that the API is running, the following should return `{"result":"pong"}`:
 ```bash
-curl -X GET http://localhost:3000/api/pingapi
+curl -X GET http://localhost:8686/api/ping
 ```
 
 If you wish to check the API's connection to a node, you can run the following for some node `<NODE>`:
 ```bash
-curl -X GET http://localhost:3000/api/pingnode?name=<NODE>
+curl -X GET http://localhost:8686/api/pingnode?name=<NODE>
 ```
 
 **Note**
 
 Using curl with multiple queries requires the entire url to be inside double quotation marks as seen in the example below:
 
 ```bash
-curl -X GET "http://localhost:3000/api/registry/nodes?name=<NODE>&height=300"
+curl -X GET "http://localhost:8686/api/registry/nodes?name=<NODE>&height=300"
