API Monitoring

Monitor your APIs.
Never miss an outage.

StatusKit.Pro checks your REST APIs, webhooks, and health endpoints around the clock. Custom headers, method support, and instant alerts when something breaks.

Built for API reliability

Real HTTP checks against your endpoints — not just pings.

📡

HTTP Methods

Monitor GET, POST, PUT, PATCH, DELETE endpoints. Send custom request bodies and headers for authenticated APIs.

🔑

Custom Headers

Pass Authorization headers, API keys, or any custom header your endpoint requires. Secrets are stored securely.

Status Validation

Configure the expected HTTP status code per endpoint. A 200 or a 204 — your choice. Anything else triggers an alert.

⏱️

Response Time SLAs

Track p50/p95 response times over time. Catch slow regressions that don't cause outright failures but hurt user experience.

🔔

Webhook Alerts

Business plan users can send downtime events to any webhook — Slack, PagerDuty, Discord, or your own incident handler.

🔌

Monitoring API

Manage your monitors programmatically. Create, update, and read monitor status via the StatusKit.Pro REST API.

Common API monitoring use cases

Teams use StatusKit.Pro to monitor all kinds of API surfaces.

🏥

Health Endpoints

Check your /health or /ping endpoints every minute. Confirm the service is alive and dependencies are connected.

🔐

Auth APIs

Monitor login and token endpoints. Catch certificate expiry, misconfigurations, or auth provider outages immediately.

📦

Third-Party APIs

Monitor Stripe, Twilio, Sendgrid, or any external dependency your app relies on. Get alerted before users hit errors.

🚀

Deployment Smoke Tests

Pair monitoring with your CI/CD pipeline. Confirm every deploy leaves key endpoints responding correctly.

Frequently asked questions

Can I monitor authenticated API endpoints?

Yes. Add an Authorization or X-API-Key header to your monitor configuration. Headers are stored securely and included with every check request.

How do I monitor a POST endpoint?

Currently StatusKit.Pro sends GET requests for monitoring checks. For POST endpoint health, point your monitor at a dedicated health-check GET endpoint that validates your service is ready to accept writes.

Can I get alerted in Slack when my API goes down?

Yes — Business plan users can configure a webhook URL. Point it at your Slack incoming webhook and you'll get a message the moment a check fails.

Is there a free API monitoring plan?

Yes. The free plan monitors 1 endpoint every 5 minutes with a public status page. No credit card required.
