# List peer establishments

`GET /v1/employers/{employer_id}/peers`

## Request

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

Peer establishments — same NAICS+state cohort, plus same-parent
siblings.

Powers the "Other employers in this industry" and "Other
establishments under this parent" sections of the profile page.
These sections double as internal-link targets that pass authority
to long-tail leaf URLs (otherwise SEO dead-ends since most thin
profiles have no inbound links).

Returns up to `limit` rows per cohort, ordered by
agency_violation_count DESC so the most-active peers surface first
— better signal for the human reader and stronger anchor-text
diversity in the per-page link set.

Metered same as get_inspections. The endpoint is heavy enough
(two indexed lookups + N projections) that an unmetered version
would invite scraping.

## Path parameters

- `employer_id` string, required

## Query parameters

- `limit` integer

## Headers

- `X-Api-Key` string

## Response `200`

Successful Response

## Other responses
