Real API calls
Score APIs from real GET, PUT, POST, DELETE, and other HTTP requests.
Platform / CASC Quality
Understand API quality with one clear score.
Cloud API Service Consistency (CASC) scoring turns many performance signals into a single number out of 10, making API quality easier to compare, explain, and improve.

A comprehensive score
Like an API speed test and credit rating combined.
CASC blends API performance data, pass/fail behavior, location outliers, and historical comparisons into a single benchmarked score that updates continuously.

API quality scoring
Replace metric overload with a clear quality signal.
Too many metrics can make API quality hard to explain. CASC provides a simple, benchmarked number that shows how well an API is functioning.

Meaningful comparisons
Compare services and providers objectively.
CASC compares API quality against historical APIContext monitoring data, making it easier to understand service quality across providers, ecosystems, and APIs.

Performance outlier detection
Look beyond p50, p90, and p99.
Outlier detection algorithms analyze performance by cloud location and pass/fail behavior so teams can see quality issues that percentile summaries can hide.
