# I'm interested in evaluating tool usage (frequency, token count, execution time)

> How to analyze tool usage metrics with Atla's Data API

Our [Data API](https://docs.atla-ai.com/api-reference/overview) is set up for these situations. We also have an easy to use notebook to show you how to access traces, spans, and calculate stats (tool call durations, token counts) which you can access [here](https://github.com/atla-ai/atla-insights-sdk/blob/main/examples/atla-data-api-tool-stats.ipynb).
