How it works
We calculate a health-risk score
Signals are summed and boosted if daily failed requests reach 500 or more, since high failure volume signals real customer impact.
Get a targeted investigation plan
The recommended action matches the risk level, from routine monitoring to immediate incident investigation.

Frequently asked questions
What counts as an authentication failure spike?
A noticeable jump in failed login or token-validation attempts compared to your normal baseline — often a sign of a broken auth flow or a client-side bug rather than an attack.
Is this a replacement for real API monitoring?
No. It's a fast, rule-based check using numbers you already know. A dedicated uptime and API monitoring tool with continuous synthetic checks will catch issues in real time with far more precision.
Why does failure volume boost the score?
The same error rate matters more when it translates into a large absolute number of failed requests per day, since that's closer to actual customer impact.
