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 to get a key.
