What is my Custom Resource Definition URL in Kubernetes - rest

Question

I am trying to hit my custom resource definition endpoint in Kubernetes but cannot find an exact example for how Kubernetes exposes my custom resource definition in the Kubernetes API. If I hit the custom services API with this:
https://localhost:6443/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions
I get back this response
"items": [
{
"metadata": {
"name": "accounts.stable.ibm.com",
"selfLink": "/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions/accounts.stable.ibm.com",
"uid": "eda9d695-d3d4-11e9-900f-025000000001",

"customresourcecleanup.apiextensions.k8s.io"
]
},

},
"scope": "Namespaced",

}
],

}
},

{

},
{

"lastTransitionTime": "2019-09-12T22:26:20Z",
"reason": "InstanceDeletionCheck",

}
],
"acceptedNames": {

}
This leads me to believe I have correctly created the custom resource accounts. There are a number of examples that don't seem to be quite right and I cannot find my resource in the Kubernetes REST api. I can use with my custom resource from kubectl but I need to expose it with RESTful APIs.
https://localhost:6443/apis/stable.example.com/v1/namespaces/default/accounts
returns
404 page not found
Where as:
https://localhost:6443/apis/apiextensions.k8s.io/v1beta1/apis/stable.ibm.com/namespaces/default/accounts
returns
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {},
"status": "Failure",
"message": "the server could not find the requested resource",
"reason": "NotFound",
"details": {},
"code": 404
}
I have looked at https://docs.okd.io/latest/admin_guide/custom_resource_definitions.html and https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/
The exact URL would be appreciated.

This is a quite decent way retrieving K8s REST API resource executing kubectl get command on some top debugging levels, like #Suresh Vishnoi mentioned in the comment:
kubectl get <api-resource> -v=8
Apparently, eventually checked by #Amit Kumar Gupta, the correct URL accessing custom resource as per your CRD json output is the following:
https://<API_server>:port/apis/stable.ibm.com/v1/namespaces/default/accounts
Depending on the authentication method you may choose: X509 Client Certs, Static Token File, Bearer Token or HTTP API proxy in order to authenticate user requests against Kubernetes API.
