Meter connects the dots
Know who used what
Attribute each call, token, agent action, or custom event to the right customer.
Control usage before cost
Apply allowances and limits before expensive AI work runs.
Know when the pattern changes
Get email or Slack alerts when usage or spend breaks from its learned baseline.
When seats stop measuring usage
Your next power user may not be a person.
One customer can launch dozens of agents, automations, and background workflows without adding a single seat. UsageTap connects that machine work to the customer account, so you can include usage, charge overages, or enforce limits.
Illustrative customer scenario
Margin at riskStarting contract
10 paid seats
Revenue is tied to ten people.

Automations run without creating new seats.

8× more AI work
Provider cost grows while seat revenue stays flat.

Metering uncovered optimization they weren't looking for.
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.

UsageTap for AI agentsMCP
Connect your agents to customer usage.
Connect Claude, ChatGPT, Codex, or your own MCP-compatible agents and workflows to review customer allowances, spot unusual usage, and compare recorded AI costs.
Requires a UsageTap account. Read-only access: the connection cannot change plans, contact customers, or modify account data.
Try asking your agent
- Which customers need attention because of low remaining allowance or unusual recent usage?
- Show me our active customers and their current account status.
- Summarize our AI usage over the last seven days and rank the models by recorded cost.
Answers use the customer and usage data recorded in your UsageTap account.

UsageTap Guard
Investigate changing behavior
API usage shifts toward exports. LLM output sizes change. Guard compares reported application behavior to help investigate significant changes that may indicate misuse or runaway work, even when totals stay steady.
- LLM behavior: cache reuse, output/input ratios, output sizes and recorded cost per completed application call.
- API and agent work: feature and task-type consumption shares, plus reported API call rate against its daily pattern.
- Custom meters: feature and task-type shares of pages, searches or other units within the same application meter.
Comparisons need enough usable history. Organization admins inspect saved evidence; a finding is a reason to investigate.
Spend protection
Set known boundaries. Watch usage and spend.
Configured allowances and limits enforce policy when your application checks them before work begins. Forecasts show where usage is heading; general anomaly alerts flag confirmed usage or spend anomalies.
Usage or spend spikes: A new workflow may be taking off—or an automated process may be running away.
Budget burn accelerates: Projected month-end spend may be crossing the budget your team configured.
A customer nears a limit: A hard boundary can stop known overages before expensive work begins.
Provider-reported spend is authoritative daily; metered calls add faster hourly estimates.
See how spend protection works →Email and Slack notifications are opt-in and default off. Alerts support investigation; configured Meter limits enforce policy separately. Guard does not automatically block activity.
Customer-facing usage
Give every customer a clear view of their usage.
Put current consumption, remaining allowance, forecast, and plan status inside your product. Customers can act before a limit or invoice becomes a surprise.
Match usage to the language of your product
Show plan status without exposing provider costs
Keep customers and account teams on the same record
Install Meter with your coding agent
Point Codex, Claude Code, Cursor, or Copilot at the UsageTap integration guide. It will locate your provider calls, preserve your existing SDK, add customer attribution and pre-call policy checks, and run the relevant tests.
UsageTap Compress
Reduce application context. Keep what the task needs.
Compact structured context during model calls or turn reusable source material into smaller, task-ready context—with checks for the facts, values, structure, and behavior that must remain.
