# List available geographic regions

`GET /api/v1/regions`

Returns the full list of geographic regions available for filtering forecasts,
driver searches, and alert detection. Use the `id` value from each entry
in the `filters.regions` field of your requests.

This is a discovery endpoint — region ids are **not** validated on submit,
so you can filter by any integer in 1–9999, but this listing shows the ones
that actually exist in the catalog.

## Response `200`

Full region listing, sorted by `id` ascending.

- RegionListResponse
  - `items` RegionItemV1[], required — Complete region listing, sorted by id ascending. No pagination.
    - `id` integer, required — Integer identifier. Use this value in filters.regions[].
    - `latitude` number, double, required — Geographic latitude (0.0 when not applicable).
    - `longitude` number, double, required — Geographic longitude (0.0 when not applicable).
    - `name` string, required — Human-readable region label.

## Other responses
