# List jurisdiction groups

`GET /jurisdictions/groups`

Public metadata — no API key required.

Returns the canonical bundles for states whose feed is split across
multiple codes (state + WZDx + optional CWZ + optional sub-state
regional). Querying `?jurisdiction=<primary_jurisdiction_code>` on
`/events` or `/features` is transparently expanded to all members.

## Response `200`

Array of jurisdiction groups

- JurisdictionGroup[]
  - `description` string
  - `id` string, required — Stable slug, e.g. `us-ca`, `us-co`, `us-tx`.
  - `members` string[], required — Jurisdiction codes in this group, primary first. Includes the state feed plus its `WZDX_<STATE>`, optional `WZDX_CWZ_<STATE>`, and any sub-state regional siblings.
  - `name` string, required
  - `primary_jurisdiction_code` string, required — The canonical state/province code (`CA`, `CO`, `TX`). Querying this code on `/events` or `/features` auto-expands to all `members`.
  - `sort_order` integer
