One API key. Every diagnostic.

Sign in to generate a key, then call DNS, SSL, WHOIS, and network checks straight from your own scripts, dashboards, or CI — the same diagnostics running behind every tool on this site.

  • 20 diagnostic endpoints, one JSON contract
  • 300 free requests a day, no credit card
  • Checks run from NetSH infrastructure, not your browser
