API monitoring

A 200 response does not mean your API is healthy.

Validate status, headers, JSON values and response time. Detect logical failures that basic uptime checks miss.

Built for signal

Monitoring that tells you what matters.

Configure precise expectations, confirm failures and keep the context required to act quickly.

JSONpath assertions

JSON assertions

Check exact values at nested JSON paths, including booleans, numbers and strings.

Custom methods

Monitor GET, POST and other endpoint behavior with controlled request configuration.

Headers & authentication

Supply encrypted credentials and the headers required by private APIs.

Performance thresholds

Fail slow endpoints even when their payload remains technically correct.

Logical failure detection

Catch responses such as success: false even when the HTTP status is 200.

Incident correlation

Confirm failures, open one incident and resolve it automatically on recovery.

How it works

From setup to evidence in four steps.

No separate monitoring infrastructure and no opaque alert pipeline.

  • Add the API endpoint and method
  • Configure headers using encrypted secrets
  • Define expected status and JSON values
  • Choose alert channels and confirmation policy

Perfect for
