Uptime Monitoring API Guide

The uptime monitoring API lets you check website availability programmatically, retrieve uptime data, and integrate uptime monitoring into your applications. Instead of manually checking if sites are up, you can automate the entire process.

The API returns structured JSON data that is easy to parse and analyze. Each check returns uptime status, response time, and any issues detected—one API call gives you the uptime picture.

This guide shows you how to use the uptime monitoring API, with step-by-step examples and integration patterns.

Start by getting your API key from the MonitorMojo dashboard. The API key authenticates your requests and tracks your credit usage. Keep your API key secure and do not expose it in client-side code.

Next, review the API documentation. The documentation provides detailed information about endpoints, request parameters, response formats, and error codes. Understanding the API structure will help you integrate it effectively.

Then, test the API with a simple request. Run an uptime check on a test domain and verify that you receive a successful response. This confirms that your API key is working and that you understand the request format.

Finally, integrate the API into your application or workflow. Use the API to run uptime checks on schedule, retrieve results, and take actions based on the uptime data.

To run an uptime check, send a POST request to the check endpoint with the domain you want to check. The API will check if the website is reachable and return structured JSON data.

The response includes uptime status, response time, and any issues detected. Parse the JSON response to extract the data you need and take appropriate actions.

You can run checks on schedule (every minute, every 5 minutes, hourly) or in response to events (after deployments, when users report issues, etc.). The API makes it easy to automate the entire process.

MonitorMojo provides historical data, so you can analyze uptime trends over time. What is the uptime percentage? Are there patterns in when downtime occurs? This data helps you provide more intelligent insights.

Not handling errors properly is a common mistake. The API can return errors for various reasons: invalid API key, insufficient credits, invalid domain, etc. Handle errors gracefully and provide meaningful feedback to users.

Not securing your API key is another mistake. Exposing your API key in client-side code or public repositories can lead to unauthorized usage and credit consumption. Keep your API key secure.

Not parsing responses correctly is a third mistake. The API returns structured JSON data, but you need to parse it correctly to extract the information you need. Test your parsing logic thoroughly.

Not monitoring API usage is a fourth mistake. Track your API usage to ensure you are not exceeding your credit limits. MonitorMojo provides usage data in the dashboard.

MonitorMojo provides a REST API with clear endpoints, structured responses, and comprehensive documentation. The API is designed for easy integration into applications and workflows.

The API returns structured JSON data that is easy to parse and analyze. Each check returns uptime data in a format that applications can work with.

MonitorMojo also provides historical data, so you can analyze uptime trends over time and provide more intelligent insights.

The credit-based pricing means you only pay for the checks you run. No per-site monthly fees. This makes it easy to scale your API usage without breaking the budget.

Uptime Monitoring API Guide is best understood as a repeatable website health workflow, not a promise that every outage or configuration issue will be avoided. Learn how to use the MonitorMojo uptime monitoring API to check website availability, retrieve uptime data, and integrate uptime monitoring into your applications.

In practice, this workflow centers on API, CLI, and AI-agent workflows that retrieve website health context with human review. Each check is planning input: it can show that a monitored endpoint is reachable, that a certificate has a given expiry window, that response time has shifted, or that a header is missing. It cannot prove root cause by itself or replace a human response. The value is in making the review consistent enough that AI-agent builders and automation teams can spot issues before someone downstream has to ask about them.

Beyond that primary audience, the same checks are reusable by anyone with a public-facing URL that matters to revenue, leads, or reputation: a recurring review is cheap insurance compared to hearing about the problem from a client or customer first.

Start by listing the URLs that actually matter instead of just the homepage — for an AI agent retrieving website health context before a human reviews it, that usually means the pages tied to revenue, signups, or trust, not every page on the site.

Next, define the check types for each URL: reachability, HTTP status, HTTPS/SSL certificate status and expiry window, response time, redirect behavior, and security header presence. For API, CLI, and AI-agent workflows, document which endpoint or command runs the check and where the result is stored.

Set a cadence that matches the risk — a low-traffic page may only need a monthly look, while a page tied to revenue or signups deserves a check after every deployment and before any campaign or launch.

Record what you find with a consistent format: URL, check type, status, issue, owner, detected date, and next review date. Then say what actually happened in plain language — a check can surface a symptom, but AI-agent builders and automation teams still need to confirm the cause.

• Choose the URLs that matter most to visitors, clients, revenue, and operations.
• Run uptime, SSL, response time, and security header checks on a consistent schedule.
• Triage failed or risky checks by likely owner: hosting, DNS, SSL, code, platform, or third party.
• Record notes in a repeatable format so future reviews do not start from scratch.
• Send a plain-language summary with the issue, impact, owner, and next review date.
• Run a confirmation check after remediation so there is an external result to reference.

Use this template for recurring reviews: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Resolved Date], [Next Review Date]. Add a one-line summary at the top: what changed, what needs attention, and who owns the next step.

For AI-agent builders and automation teams, group findings into the four signals that matter most: reachability, SSL status, response time, and security headers. Where nothing needs action, say the check found no issue in that area rather than implying full coverage.

• [URL]: the exact page or endpoint checked.
• [Check Type]: uptime, SSL, response time, headers, API, CLI, or agent workflow.
• [Status]: pass, review, failed, blocked, or needs human investigation.
• [Issue]: the observable symptom, not an unsupported root-cause claim.
• [Owner]: agency, developer, host, DNS provider, client, or third-party vendor.
• [Next Review Date]: when the team should confirm status again.

The most common mistake is monitoring only the homepage while a checkout, signup, or booking flow silently breaks. Another is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch that before a browser warning does.

For AI-agent builders and automation teams specifically, the recurring miss is treating one clean check as proof the whole site is fine, or fixing an issue without ever writing down what happened — which means the next person repeats the same investigation from zero.

• Tracking too many low-value URLs while missing the ones that matter.
• Skipping notes after an issue is resolved.
• Reporting a status without an owner or next step attached.
• Assuming automation can resolve an incident without human review.
• Treating one clean check as proof that every risk is covered.

Consider an AI agent retrieving website health context before a human reviews it. A scheduled check flags that a monitored endpoint is slower than its usual baseline and that a security header is missing. Instead of guessing, the team logs the observation with a timestamp, assigns an owner, and re-checks after the fix ships — turning a vague "something feels off" into a specific, closed-loop task.

MonitorMojo runs website health checks that combine reachability, SSL certificate status, response time, and security header presence in one workspace, so this workflow doesn't require stitching together several separate tools.

The API and CLI make the same checks scriptable for AI-agent builders and automation teams who want them wired into an existing process, while credit-based checks keep it practical to run reviews exactly when they matter — before a client call, after a deploy, or when someone asks whether a monitored endpoint is healthy. Results still depend on hosting, DNS, and how quickly the responsible team acts on what the check finds.
