Everything Your APIs Need To Stay Reliable

Purpose-built tools for modern engineering teams to proactively monitor, test, and validate their API infrastructure.

Predict Failures Early

Machine learning detects abnormal latency and error patterns before incidents occur.

Failure Probability: 84%

Test APIs Like Postman

Built-in API testing kit with request builder, response viewer, and contract validation.

GETapi.acme.com/users
{ "status": 200, "data": [] }

Contract Intelligence

Automatically detect schema mismatches, missing fields, and breaking changes.

Telemetry Insights

Track latency, error rates, and request patterns across all endpoints globally.

From Traffic to Insights

Step 01

Connect APIs

Upload OpenAPI specs or integrate live telemetry feeds.

Step 02

Analyze Traffic

ApiCortex processes telemetry and extracts patterns.

Step 03

Predict Risk

ML models detect anomalies and forecast failures.

Step 04

Act Promptly

Get alerts and fix issues before users notice.

Stop Guessing. Start Knowing.

The difference between traditional API monitoring and ApiCortex is night and day.

Without ApiCortex
$ curl https://api.acme.com/v1/users
{"error": "Internal Server Error"}
$ curl https://api.acme.com/v1/orders
Request timeout after 30s
# Wait... was that a schema change?
# Check logs manually at 3am...
# Customers already reported outage
With ApiCortex
$ apicortex monitor users-service
[OK] Contract validated against OpenAPI spec
[WARN] Latency spike detected on GET /users
[INFO] ML prediction: 84% risk of failure
$ apicortex test --contract orders-service
[PASS] 42/42 endpoints validated
[PASS] 0 breaking changes detected
[PASS] CI/CD gate: deploy approved
