cost-estimator.py

Map token counts to USD costs for various models.

python3 scripts/cost-estimator.py --input 1000 --output 500 --model claude-opus-4
python3 scripts/cost-estimator.py --input 1000 --output 500  # shows all models

usage-analyzer.sh

Analyze OpenClaw usage logs to find spending patterns.

bash scripts/usage-analyzer.sh [--days 7] [--log-dir ~/.openclaw/logs]
