# List Cost Pools

`GET /aurd-tracking/{claim_id}/cost-pools`

## Request

- Base URL: `https://api.claimkit.co` (the document declares no server; this is the origin it was published from)
- URL: `https://api.claimkit.co/aurd-tracking/{claim_id}/cost-pools`
- Auth: none declared

List the claim's cost pools — a read-only mirror of its expenditures.

The persisted pools are rebuilt from the categorised expenditure data on
every read (see ``rebuild_cost_pools_from_expenditures``): one pool per
non-salary expenditure category, with per-activity apportionment derived
from the expenditure apportionments. There is no manual add/edit/sync.

## Path parameters
