# list_domains

`GET /v1/domains`

## Request

- Base URL: `https://ndi-api.nace.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://ndi-api.nace.ai/v1/domains`
- Auth: API key in header `X-API-Key`
- TypeScript: <https://skmtc.dev/nace/apis/ndi-service/docs/v1/domains/get.ts> (a function with typed inputs; its response is checked against the schema)

List every domain visible to the caller. Cost class: cacheable.

Returns the platform-owned domains (``generic`` and the curated verticals,
all published and selectable) and the calling tenant's own rows.

Args:
    session: Database session.
    caller: The authenticated tenant.
    owner: Restrict to ``platform`` or ``tenant`` rows.
    status: Restrict to ``draft`` or ``published`` rows.
    cursor: Opaque cursor from a previous page.
    limit: Rows per page.

Returns:
    One page of domain summaries with an exact total.

## Query parameters

- `status` 'draft' | 'published', nullable: Filter by lifecycle status.
- `cursor` string, nullable: Opaque cursor from a previous page's `next_cursor`. Omit for the first page.
