-<h2>JSON-RPC Services</h2>
+## Example
+
+To call JSON-RPC methods, you need to create the JSON-RPC request:
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 1,
+  "method": "pactus.network.get_node_info",
+  "params": {}
+}
+```
+
+> Make sure you always add the `params` field, even if no parameters are needed, and ensure you use curly braces.
+
+Then you use the `curl` command to send the request to the node:
+
+```bash
+curl --location 'http://localhost:8545/' \
+--header 'Content-Type: application/json' \
+--data '{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "method": "pactus.network.get_node_info",
+    "params": {}
+}'
+```
+
+> Before sending the request, you need to enable the JSON-RPC service inside the
+> [configuration](/get-started/configuration/).
+
+### Using Basic Auth
+
+If you have enabled the [gRPC Basic Authentication](/tutorials/grpc-sign-transactions/),
+then you need to set the `Authorization` header.
+
+```bash
+curl --location 'http://localhost:8545/' \
+--header 'Content-Type: application/json' \
+--header 'Authorization: Basic <BASIC-AUTH-TOKEN>' \
+--data '{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "method": "pactus.blockchain.get_account",
+    "params": {
+        "address": "pc1z2r0fmu8sg2ffa0tgrr08gnefcxl2kq7wvquf8z"
