SSL Monitoring API

SSL Monitoring API for Certificate Checks

MonitorMojo provides an SSL monitoring API for checking certificate status programmatically. Track expiration dates, verify HTTPS configuration, and integrate SSL monitoring into your workflow.

The Problem

Small misses turn into public failures fast.

Certificate checks belong in automation, not just a dashboard

A team running infrastructure-as-code or scheduled jobs needs certificate validity as a callable check, not a page to click into.

Scraping a dashboard for expiry dates doesn't scale

Some teams resort to screen-scraping a monitoring UI just to get certificate data into their own systems — a fragile workaround for what should be an API call.

Custom SSL-checking scripts are a maintenance burden

Hand-rolled certificate-checking scripts using raw TLS libraries work, but somebody has to maintain them indefinitely.

How It Works

1

Add your domain

Enter the website, subdomain, or client property you need to protect.

2

MonitorMojo checks it

Run a real reachability, HTTPS/SSL, response time, and configured health check.

3

Review what needs attention

Use the returned signals to decide what to fix before a browser error or complaint.

Features

Website health checks built for the signals teams forget until they hurt.

api

Certificate status via API

Call an endpoint and get certificate validity, expiry date, and issuer details back as structured data.

terminal

CLI wrapper included

Run the same certificate check from the command line without writing an API client first.

event

Expiry data your scripts can act on

Get an expiry date in a format your own alerting or automation can compare against a threshold.

schedule

Callable on your own schedule

Trigger checks from cron, a CI job, or your own scheduler instead of relying on a fixed monitoring interval.

code

No TLS library maintenance

Get certificate data through one API call instead of maintaining your own certificate-inspection code.

search_check

On-demand or scheduled

Call the check exactly when you need fresh certificate data, not on someone else's polling schedule.

Who This Is For

Built for teams closest to the website.

Developers automating certificate checks

Replace a hand-rolled TLS-checking script with a maintained API call.

Teams with existing alerting infrastructure

Feed certificate expiry data into alerting systems you already run.

Agencies building internal tools

Pull certificate status into an internal client-portfolio tool instead of a generic dashboard.

Why MonitorMojo

Simple checks for real website risk.

API-first, not a dashboard afterthought

The API returns the same structured certificate data the dashboard displays, built to be consumed programmatically from the start.

Credit-based pricing

Pay for checks your automation actually triggers instead of a flat monitoring fee.

One less script to maintain

Retire a hand-rolled certificate-checking script in favor of a maintained endpoint.

Workflow Guide

What this workflow means

SSL monitoring API that enables developers to check SSL certificate status programmatically, track expiration dates, and integrate SSL monitoring into their workflows.

In practice, that means reviewing SSL certificate status, certificate expiry windows, renewal ownership, and post-renewal confirmation from one repeatable process instead of waiting for developers and AI-agent builders to hear about a problem secondhand. A check can show whether a URL is reachable, whether SSL appears valid, how quickly the server responds, and whether selected headers are present — it does not replace a security audit or an incident-response team, but it makes the underlying signals visible before they turn into a bigger issue.

Who should use this

This is built for developers and AI-agent builders — specifically for the moment of scripting a check into a deploy pipeline or agent workflow. A team running infrastructure-as-code or scheduled jobs needs certificate validity as a callable check, not a page to click into. The same workflow is reusable by anyone with a public URL tied to revenue, leads, or reputation.

Detailed step-by-step workflow

Start by listing the URLs that actually matter for scripting a check into a deploy pipeline or agent workflow — not every page on the site, just the ones tied to revenue, signups, or trust. Define the check types for each: reachability, HTTP status, HTTPS/SSL status and expiry window, response time, redirects, and security header presence.

Set a cadence that matches the risk: a monthly review for low-traffic pages, a check right after every deploy for anything tied to revenue. When something fails, triage before assuming cause — hosting, DNS, SSL, code, cache, or a third-party script could all be responsible. Record an owner and a next review date, then re-check after the fix ships.

Checklist and template

Use this template for every review: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Next Review Date]. Describe what the check observed before assigning a root cause — 'response time increased' is a fact, 'hosting is the problem' is a guess until confirmed.

For a recurring report, group findings by reachability, SSL, response time, and security headers, and say plainly when a signal showed no issue rather than implying full coverage.

Common mistakes

The most common miss for developers and AI-agent builders is checking only the homepage while a checkout, signup, or booking flow silently breaks. A close second is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch it before a browser warning does. The biggest framing mistake is treating one clean check as proof the whole site is covered.

Practical example

Picture scripting a check into a deploy pipeline or agent workflow. A scheduled check flags that a key page is slower than its usual baseline and a security header is missing. Call an endpoint and get certificate validity, expiry date, and issuer details back as structured data. Instead of guessing, the team logs the observation, assigns an owner, and re-checks after the fix — turning "something feels off" into a closed-loop task with a timestamp attached.

How MonitorMojo helps

MonitorMojo runs the checks behind ssl monitoring api for certificate checks — reachability, SSL, response time, and security headers — from one dashboard, with an API and CLI for teams that want it scripted into an existing workflow. Credit-based checks make it practical to run a review exactly when it matters: before a client call, after a deploy, or the moment someone asks whether the site is healthy.

FAQ

Questions teams ask before they check website health.

What certificate data does the API return?

Structured data including validity status, expiry date, and issuer details for the checked domain, suitable for parsing in your own scripts or automation.

Can I call this from a script instead of a dashboard?

Yes. The API is designed to be called directly from your own automation, cron jobs, or CI pipeline, not just clicked through in a UI.

Is there a CLI, or only a REST endpoint?

Both. The CLI wraps the same API so certificate checks can be run from the command line. See /cli for details.

Can I feed expiry data into my own alerting system?

Yes. The structured expiry date returned by the API can be compared against your own threshold in whatever alerting system you already use.

Where's the full API documentation?

Full documentation, including authentication and response formats, is available at /api-docs.
