package main

)

func main() {
	client := &http.Client{Timeout: 10 * time.Second}
	res, err := client.Get("https://api.domainsdb.info/")
	if err != nil {

Trimmed from the live response on Oct 24, 2026.

JSON

{
  "message": "DomainsDB API is running.",
  "status": "OK"
}

4. Before you ship

Set a timeout and handle non-200 responses: free APIs can rate-limit or go down.
Cache responses where you can, instead of calling the API on every page view.
Read the official documentation ↗ for rate limits and terms of use.
