🚀 Launch Announcement

We’re excited to share that Site Informant — the affordable website uptime monitoring service — now provides a public JSON API for developers and AI tools.

With one simple GET request, you can pull live uptime, response-time, and SSL-certificate data for any site you monitor (or any site that’s opted-in for public visibility).

GET https://api.siteinformant.com/api/public/status/prudentdev.com

💡 Example response
{
"domain": "prudentdev.com",
"uptimePercent": 100,
"isOnline": true,
"lastCheckUtc": "2025-11-04T07:45:00Z",
"averageResponseMs": 238,
"sslExpiresUtc": "2026-01-04T00:00:00Z",
"sslIssuer": "Let's Encrypt"
}
