API Monitoring

Your APIs are your product

When your API goes down, your customers' apps break. Monitor every endpoint, track response times, and get alerted before your users file tickets.

Everything you need for API reliability

Built by developers, for developers. Monitor any HTTP endpoint with the depth your APIs deserve.

Response Validation

HTTP 200 isn't enough

Your API can return 200 OK and still be broken. Use keyword monitoring to verify response content. Check for expected JSON fields, error messages, or specific values.

  • ✓ Check for "status":"ok" in JSON responses
  • ✓ Alert if "error" appears in response body
  • ✓ Catch application-level failures that status codes miss
// Your API response:
{"status": "ok", "data": {"users": 3247, ...}}

// Appulsemonitor checks:
keyword: "status.*ok"
keyword_type: "contains"
alert_if_missing: true
