Automated monitoring for
APIs, JSON and endpoints
Instant alerts when an API endpoint changes, returns a different structure, or modifies critical values. Prevent production issues.
Common problems
Do these sound familiar?
Unstable APIs
Third-party endpoints change without notice. Your application breaks and customers complain.
JSON structures changed
A renamed field or changed data type in the API response can break your entire integration.
Critical values modified
Rate limits, API versions, configurations — values that if changed directly affect functionality.
No traceability
When something breaks you don't know exactly when the API changed. Without history, debugging takes hours.
How it works
Add your endpoints
Enter the API or JSON URLs you want to monitor, with optional headers.
We monitor the structure
We check JSON structure, key values, status codes and response times.
Instant alert
When any change is detected you get a notification showing exactly what changed.
What you get
JSON structure detection
Any change in response structure — new, deleted or renamed fields — detected automatically.
Instant alerts
Email, Slack, Telegram — get notified before your users notice the problem.
Change history
Know exactly when the API changed. Fast debugging, no hours investigating logs.
Multi-endpoint monitoring
Monitor all critical endpoints simultaneously from the same dashboard.
Prevent production issues
Detect breaking changes before they affect end users.
Third-party monitoring
Payment APIs, delivery, authentication — monitor any external service you depend on.
A development team detected that a payment provider's API changed its error response structure. They updated the integration in 2 hours, before the issue reached end customers.
Real case studies
Fintech startup: API error detected in 2 hours
A payment provider API changed its error response structure. The integration was updated before it reached customers.
Agency: 18 endpoints monitored automatically
Simultaneous monitoring for all critical endpoints — payments, delivery, authentication.
SaaS: breaking change detected before deploy
A JSON structure change in a third-party API was detected 6 hours before the next deploy.

Does it work with APIs that require authentication?
Yes, you can configure custom headers including Authorization tokens for private APIs.
Does it monitor HTTP status codes?
Yes, any status code change (e.g. 200 to 500) generates an immediate alert.
How often are endpoints checked?
Depending on plan: every 24h, 12h, 6h, 1h or even 5 minutes for higher plans.
Can I ignore certain JSON fields that always change?
Yes, you can configure fields to ignore (e.g. timestamps, counters) to eliminate false alerts.
