Developer-First API Monitoring

Validate Payloads.
Not Just Status.

Deep endpoint monitoring with JSON assertions, header validation, and global latency tracking. Ensure your production APIs return exactly what your frontend expects.

JSON Assertions

Validate specific fields, data types, and values in your JSON responses.

Header Validation

Ensure security headers and content-types are correctly set.

Latency Alerts

Get notified if your API slows down, even if it stays &quot;up&quot;.

Global Edge

Monitor performance from 15+ edge locations simultaneously.

Deep Validation

Validate your
Business Logic.

An HTTP 200 status code only means the server is there. Monitor Hub goes deeper by asserting that your API actually returned the correct data structure and values.

Schema Enforcement
Ensure response bodies follow your expected JSON schema.
Content-Type Matching
Verify headers like application/json or text/xml are set.
ASSERT

Performance is a
Feature.

Slow APIs are just as bad as down APIs. Track latency percentiles (P95, P99) across all your endpoints and get alerted on performance regressions.

API Monitoring
FAQs.

How is API monitoring different from Uptime monitoring?

Uptime monitoring usually only checks if a server responds (ping/HTTP 200). API monitoring validates that the returned data is correct, the latency is within limits, and the headers are secure.

Can I monitor POST or PUT requests?

Absolutely. Monitor Hub supports all standard HTTP methods (GET, POST, PUT, DELETE, PATCH, OPTIONS). You can also configure request bodies, headers, and query parameters.

What are JSON assertions?

JSON assertions allow you to define rules that the response body must follow. For example, you can assert that a 'success' field is true, or that an 'id' field is a valid UUID.

Does Monitor Hub support global latency tracking?

Yes. We track response times from 15+ global locations simultaneously, allowing you to see how your API performs for users in different regions.
