## 🔧 API Usage

### CostTracker
```python
from openadapt_evals.benchmarks.monitoring import CostTracker

tracker = CostTracker(run_id="eval", output_file="costs.json")
tracker.record_worker_cost(
    worker_id=1,
    vm_tier="medium",
    is_spot=True,
    hourly_cost=0.048,
    runtime_hours=0.5,
    tasks_completed=10
)
report = tracker.finalize()
print(report.generate_summary())
```

### Cost Calculator
```python
from openadapt_evals.benchmarks.monitoring import calculate_potential_savings

result = calculate_potential_savings(
    num_tasks=154,
    enable_tiered_vms=True,
    use_spot_instances=True,
)
print(f"Savings: {result['savings_percentage']}%")
```
