API monitoring

API Monitoring

Know when your API stops working.

Monitor API endpoints continuously and detect downtime, unexpected responses, timeouts, and performance problems before they affect your users.

Capabilities

Monitor the API conditions that matter

Go beyond a basic ping by configuring the request and the response your endpoint should return.

Endpoint availability

Check whether an HTTP or HTTPS API endpoint can be reached.

GET, POST, and HEAD

Use the request method appropriate for the endpoint being monitored.

Expected status

Define which HTTP status codes count as healthy.

Response time

Record endpoint latency for each completed check.

Custom headers

Add supported authentication or application headers to requests.

Timeout conditions

Configure how long UptimePilot should wait for a response.

Process

How API monitoring works

A scheduled request turns endpoint behavior into a result you can act on.

  1. 1

    Configure the endpoint, method, headers, and timeout.

  2. 2

    UptimePilot sends the request on the selected interval.

  3. 3

    The response status and timing are recorded.

  4. 4

    The result is evaluated against the expected status codes.

  5. 5

    Failed checks can create incidents and send push or email alerts.

Use cases

API monitoring for real-world systems

Monitor the endpoints that connect your product and keep important workflows moving.

REST APIs

Check public REST endpoints with the method and headers they require.

SaaS backends

Watch the endpoints behind user-facing product flows.

Mobile app APIs

Monitor services your mobile application depends on.

Payment APIs

Check your own payment-related service endpoints for availability.

Authentication endpoints

Detect timeouts and unexpected status codes on auth services.

Internal production APIs

Monitor reachable internal endpoints and production services.

Inside UptimePilot

Request configuration without the noise

UptimePilot keeps the important request settings and recent results together so developers can see what was checked and why it failed.

Request methods

Configure GET, POST, or HEAD for the endpoint being checked.

Flexible checks

Set monitoring intervals and request timeouts per endpoint.

Response analytics

Review response-time history for monitored APIs.

FAQ

Questions, answered.

What is API monitoring?+

API monitoring sends scheduled requests to an endpoint and records whether it is available, how quickly it responds, and whether the response matches configured conditions.

Can UptimePilot monitor REST APIs?+

Yes. UptimePilot can monitor reachable REST API endpoints over HTTP or HTTPS.

Can I use POST requests?+

Yes. POST is supported, alongside GET and HEAD methods.

Can I configure expected status codes?+

Yes. Each HTTP monitor can define the response status codes that count as successful.

Can I add custom headers?+

Yes. Custom headers can be added for supported authentication and request configuration needs.

Can I monitor API response time?+

Yes. UptimePilot records response time for API checks and makes that history available for review.
