API Monitoring
Ensure API reliability with proactive API monitoring.
Stay one step ahead with instant alerts on API downtime, slow responses, or unexpected response bodies. Monitor REST endpoints from 200+ global edge locations.
Response Validation
Validate JSON response bodies, check specific fields, and ensure your API returns the data your clients expect.
Latency Tracking
Track p50, p95, and p99 response times across all regions. Set latency thresholds and get alerted before SLAs are breached.
Custom Headers & Auth
Send custom headers, bearer tokens, API keys, and request bodies. Test authenticated endpoints without exposing credentials.
Multi-Step Checks
Chain multiple API calls together to test complex workflows. Verify login, create, read, update, and delete sequences.
How it works
Configure your endpoint
Set the URL, HTTP method, headers, and expected response. Support for GET, POST, PUT, PATCH, and DELETE.
Validate from the edge
Edge workers call your API from multiple regions, checking status codes, response times, and body content.
Alert on anomalies
Get notified when status codes change, response times spike, or response bodies do not match expectations.
Assertions
Validate every aspect of the response
Define assertions on status codes, response headers, body content, and JSON paths. If any assertion fails, you get alerted immediately with the full response details for rapid debugging.
Performance
Catch slowdowns before they become outages
API performance degrades gradually before failing completely. Track response time trends across regions and set degradation thresholds to catch issues early. Historical charts help you correlate performance with deployments.
