# Introduction

> Search, register, and manage domains, configure DNS, and embed domain checkout in your own product.

The Dotlet API gives your application programmatic control over domain registration and DNS management. Use it to:

* **Search and check availability** for domain names, with live pricing.
* **Register, renew, and manage domains** without a registrar dashboard.
* **Manage DNS records**; create, update, and sync A, CNAME, MX, TXT, and other record types.
* **Embed a hosted checkout** so your own users can search for and purchase domains inside your product.

All requests and responses use JSON over HTTPS. Every endpoint requires authentication, see [Authentication](/authentication) to get a key.
