Cloud API Service Consistency

CASC turns API behavior into a 0–10 confidence signal.

CASC blends pass rates, error rates, outliers, and performance consistency into a single benchmark score. A fast API can score poorly if it behaves inconsistently; a slower API can score well if it is predictable.

8.00–10.00Healthy

Few if any issues detected.

6.00–7.99Needs attention

Issues are impacting expectations.

0.00–5.99Poor performance

Significant problems to investigate.
