# Get parent (rolled-up business) cluster

`GET /v1/parents/{company_id}`

## Request

- Base URL: `https://api.fastdol.com`
- URL: `https://api.fastdol.com/v1/parents/{company_id}`
- Auth: API key in header `X-Api-Key`
- TypeScript: <https://skmtc.dev/fastdol/apis/fastdol-api/docs/v1/parents/:company_id/get.ts> (a function with typed inputs; its response is checked against the schema)

Get a rolled-up-business cluster: all establishments (sites) that share
a company_id, plus the company's confidence + cohesion + fragility, and
per-establishment summary rows.

"Parent" here is the product-facing grain (per the 2026-06-15 product-grain
revision in docs/ENTITY_RESOLUTION_ROADMAP.md). A "parent" is any
rolled-up business -- both the curated parent list and the auto-detected
company clusters surface here. Singletons return a single establishment
with `confidence: null`.

Response shape favors breadth (one row per establishment) over depth
(per-record fields). Drill to /establishments/{id} for the records under
a single site, or /employers/{id} for one record.

## Path parameters

- `company_id` string, required

## Headers

- `X-Api-Key` string

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
