Test a promptProduction proof · FocusedFit.ai
FocusedFit.ai implemented UsageTap to attribute AI usage to customers and support plans, limits, and billing. Within about a week, production visibility helped uncover a cache-breaking instruction, a silent data-truncation bug, and duplicated context.

Spend protection
Hard limits protect known boundaries. Anomaly detection watches finalized usage and spend for material changes, then routes confirmed incidents to email or Slack.
See how spend protection worksA new workflow may be taking off—or an automated process may be running away.
Projected month-end spend may be crossing the budget your team configured.
A hard boundary can stop known overages before expensive work begins.
Anomaly alerts notify your team; configured Meter allowances and limits enforce policy before work begins. Provider-reported spend is authoritative daily, while metered calls add faster hourly estimates.
Provider-neutral metering
