Usage and cost show what your traffic is actually consuming. It’s the reporting side of usage limits: limits set the cap, usage shows where you stand against it.

​
Where to see it

  • The Usage limits page shows each limit’s current usage against its threshold for the active window.
  • A key’s detail page shows requests, tokens, and estimated cost over time, broken down by model and provider.
A key's usage and cost over time

​
What’s tracked

For every key, the gateway records each day (UTC):
  • Requests: how many calls the key made.
  • Tokens: input plus output.
  • Estimated cost: in USD.
  • Routing: which incoming model and provider the caller asked for, and which target model and provider served it.

​
How cost is estimated

The gateway multiplies token counts by its cached per-model pricing. Treat it as a close estimate for tracking and budgeting, not as a replacement for your provider’s invoice.

Usage answers “how much.” For request-level detail, including inputs and outputs, latency, and the trace of each call, see Observability.
