+# isurl [![NPM Version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url]
+
+> Checks whether a value is a WHATWG [`URL`](https://developer.mozilla.org/en/docs/Web/API/URL).
+
+
+Works cross-realm/iframe and despite @@toStringTag.
+
+
+## Installation
+
+[Node.js](http://nodejs.org/) `>= 4` is required. To install, type this at the command line:
+```shell
+npm install isurl
+```
+
+
+## Usage
+
+```js
+const isURL = require('isurl');
+
+isURL('http://domain/');  //-> false
+isURL(new URL('http://domain/'));  //-> true
+```
+
+Optionally, acceptance can be extended to incomplete `URL` implementations that lack `searchParams` (which are common in many modern web browsers):
+```js
+const url = new URL('http://domain/?query');
+
+console.log(url.searchParams);  //-> undefined
+
+isURL.lenient(url);  //-> true
+```
