# Get Similar Parts For Quote

`GET /api/v1/admin/quotes/{quote_id}/similar-parts`

For each part in the quote, return up to ``k`` most similar past parts.

Anchors are restricted to past quotes that are ``QUOTED`` or
``APPROVED``, ``is_human_reviewed=True``, and have a non-null
``unit_price`` on the corresponding line item. The cohort is
further filtered to the same machining process + material so a CNC
part doesn't anchor on sheet-metal history.

The response is always well-formed: parts with no fingerprint or
no historical anchors return ``anchors=[]`` with ``n_anchors=0``
(no 404). Used by the admin quote-review UI to anchor pricing
decisions on historical analogs.

## Path parameters

- `quote_id` string, uuid, required
