# List available thematic categories

`GET /api/v1/categories`

Returns the full list of thematic categories available for filtering forecasts,
driver searches, and alert detection. Use the `id` values from this response
in the `filters.categories` field of your requests.

This is a discovery endpoint — category 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 category listing, sorted by `id` ascending.

- CategoryListResponse
  - `items` CategoryItemV1[], required — Complete category listing, sorted by id ascending. No pagination.
    - `id` integer, required — Integer identifier. Use this value in filters.categories[].
    - `name` string, required — Human-readable category label.

## Other responses

- `401` — Missing or invalid bearer token.
- `502` — Catalog service error or unreachable.
- `503` — Service Unavailable
