# Quick start (Node.js) Basic example: ```javascript const doip = require('doip') const verifyIdentity = async (url, fp) => { console.log(await doip.verify(url, fp)) } verifyIdentity('dns:doip.rocks', '9f0048ac0b23301e1f77e994909f6bd6f80f485d') ``` This snippet works en will verify the [doip.rocks](https://doip.rocks) domain as linked to Yarmo's cryptographic key using the [dns](serviceproviders/dns.md) service provider.
