FAQPage Schema
How do I analyze Claude Code token usage and cost from JSONL logs?▼

To analyze Claude Code token usage and cost, you can parse JSONL log files to calculate estimated spending, identify usage patterns by model, and detect anomalies. This process requires Python to extract and compute the token metrics from the logs.

What is the best way to track Claude Code API cost trends over time?▼

The best way to track Claude Code API cost trends is to analyze your JSONL logs to compare usage and cost metrics over different time periods. This allows you to identify patterns and anomalies in token consumption across projects and models.

Do I need Python to parse Claude Code JSONL logs for cost analysis?▼

Yes, you need Python to parse Claude Code JSONL logs for cost analysis. The Skill uses Python's built-in libraries like json, datetime, and collections to read the log files, process token usage data, and compute the estimated costs.

How can I optimize Claude Code token usage to reduce spending?▼
