Reference

What you can build

Uptime Monitoring API

Create and manage HTTP checks programmatically. Same checks, same alerting and same incident history as the ones you would create by hand — just addressable from your own code.

SSL Certificate Monitoring API

Point a check at a hostname and get told before its certificate expires — days ahead, not on the morning the browser starts refusing connections.

Domain Expiry Monitoring API

Losing a domain is the one outage you cannot fix by restarting anything. This watches registration expiry across as many domains as your plan allows.

Web Change Detection API

Watch a page for changes in what it actually says, with thresholds and keyword triggers so you hear about the changes you care about and not the rotating banner.

Cron Job Monitoring API

A job that fails loudly gets noticed. A job that silently stops running does not — because a run that never happened produces no error at all. This watches for the absence.

Scheduled Job Monitoring API

Backups, imports, exports, billing runs, queue workers — anything that is supposed to happen on a schedule and would go unnoticed for days if it stopped.
Getting started

Your first request

Every endpoint takes the same bearer token, which you will find under Account → API once you have signed in.

curl https://monitoringdaddy.com/api/v1/monitors \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Accept: application/json"

One endpoint returns every kind of check on the account. Narrow it with kind: uptime, ssl, domain, api, watch, heartbeat, or premium.

Pricing

What the API costs

Nothing extra. Anything created through the API counts against the same plan allowance as anything created in the interface, in the same pool. There is no per-call charge, no separate API tier and no credits to buy.

Build it on our API

Uptime, SSL, domain expiry, page changes and cron jobs, all from one REST API. Free plan, no card, and API access on every paid plan.
