# Get Costs

`GET /costs`

Aggregate cost data across all runs.

Scans every persisted cost file in ``.sdd/runtime/costs/``, aggregates
per-agent and per-model totals, and computes cost attainment as
``(total_spent / total_budget) * 100``.  Budget of zero is treated as
unlimited - attainment is reported as 0.0 in that case.
