+# ApiClient Plugin
+
+
+## Creating catalogs and requests
+
+```
+$ spark api:catalog --create myapp baseurl=http://127.0.0.1/app/ info="MyApp API"
+$ spark api:request --save myapp.ping url=v2/ping info="Ping the server" http.header.X-Special=magic
+```
+
+Requests are performed with the `api:request` command:
+
+```
+$ spark api:request myapp.ping
+```
+

+properties.
