 # Usage
 ## API request
-todo
+都度インスタンスやトークンを指定する場合
+``` ts
+import * as Misskey from 'misskey-js';
+
+const meta = await Misskey.api.request('https://misskey.test', 'meta', { detail: true }, 'TOKEN');
+```
+
+最初にインスタンスやトークンを指定し、以後のリクエストでその情報を使いまわす場合
+``` ts
+import * as Misskey from 'misskey-js';
+
+const cli = new Misskey.api.APIClient({
+	origin: 'https://misskey.test'
+});
+cli.i = { token: 'TOKEN' };
+
+const meta = await cli.request('meta', { detail: true });
+```
