Toolken records every request that goes through the gateway. You see cost, token usage, latency, and error rates in one dashboard. Tag a request and you can break any of those down by agent, customer, environment, or any property you choose.

​
What you can measure

Cost

What each request, agent, or customer spent.

Usage

Input, output, and cached tokens.

Performance

Latency and time to first token.

Reliability

Error rates and status codes.

​
How it works

You tag requests with metadata headers. Toolken turns each metadata key into a dimension you can group and filter by, across every metric above.
A request with no tags still shows up by model and provider. Tags add any breakdown you need on top.
