 ## Rest API. Stubs Delete
 
-!> The delete functionality is under development. It is planned to be implemented in the near future.
+Stubs Delete — endpoint removes stub by ID.
+
+Enough to knock on the handle `DELETE /api/stubs/{uuid}`:
+```bash
+curl -X DELETE http://127.0.0.1:4771/api/stubs/6c85b0fa-caaf-4640-a672-f56b7dd8074d
+```
+
+The endpoint will respond with code 204, the stub has been removed.
+
+It worked!

+## Rest API. Stubs Unused List
+
+Stubs Unused List — endpoint returns a list of unused stubs (all stubs that were not accessed through search).
+A very useful method that helps find dead stubs in the code.
+
+Let's imagine that our contract `simple.proto` looks something like this:
+```protobuf
+syntax = "proto3";
+option go_package = "github.com/bavix/gripmock/protogen/example/simple";
+
+package simple;
+
+service Gripmock {
+  rpc SayHello (Request) returns (Reply);
+}
+
+message Request {
+  string name = 1;
+}
+
+message Reply {
+  string message = 1;
+  int32 return_code = 2;
+}
+```
+
+Enough to knock on the handle `GET /api/stubs/unused`:
+```bash
+curl http://127.0.0.1:4771/api/stubs/unused
+```
+
+Response:
+```json
+[
+  {
+    "id": "6c85b0fa-caaf-4640-a672-f56b7dd8074d",
+    "service": "Gripmock",
+    "method": "SayHello",
+    "input": {
+      "equals": {
+        "name": "gripmock"
+      },
+      "contains": null,
+      "matches": null
+    },
+    "output": {
+      "data": {
+        "message": "Hello GripMock",
+        "return_code": 42
+      },
+      "error": ""
+    }
+  }
+]
+```
+
+Find stub by ID. Enough to knock on the handle `POST /api/stubs/search`:
+```bash
+curl -X POST -d '{ \
+  "id": "6c85b0fa-caaf-4640-a672-f56b7dd8074d", \
+  "service": "Gripmock", \
+  "method": "SayHello", \
+  "data":{} \
+}' http://127.0.0.1:4771/api/stubs/search
+```
+
+Now the stub is marked as used. Let's try to get a list of unused stubs.
+```bash
+curl http://127.0.0.1:4771/api/stubs/unused
+```
+
+Response:
+```json
+[]
+```
+
+It worked!
