# List Related

`GET /api/v1/verifications/{verification_id}/related`

## Request

- Base URL: `https://lenz.io`
- URL: `https://lenz.io/api/v1/verifications/{verification_id}/related`
- Auth: none declared

List public verifications semantically related to this one.

Returns the closest public-library claims by semantic similarity
(cosine distance, 0 = identical). Excludes the verification itself,
near-duplicates (distance < 0.2), and editorially-hidden claims. Empty
list when the verification has not been indexed yet (that happens
shortly after it completes) or when no claim is close enough.

Authorization model (optional Bearer) — identical to
``GET /verifications/{verification_id}``: anon callers reach listed public claims plus
API-origin unlisted ones; a valid key additionally unlocks the
caller's own claims. Results are always drawn from the public
library only, so keyless access exposes nothing new.
``limit`` is clamped to [1, 10].

**Versions.** 422: `2026-10-11` receives `ValidationErrorOut`, `2026-05-13` receives `ValidationErrorOutLegacy`; default: `2026-10-11` receives `ErrorOut`, `2026-05-13` receives `ErrorOutLegacy`.

## Path parameters

- `verification_id` string, required

## Query parameters

- `limit` integer

## Headers

- `X-Lenz-API-Version` string

## Response `200`

OK

- RelatedVerificationsOut: Wrapper for ``GET /verifications/{id}/related``. Empty ``items`` when the verification has no embedding yet (early pipeline) or no public-library claim is close enough.
  - `items` SimilarVerificationOut[]
    - `verification_id` string, required
    - `claim` string, required
    - `verdict` string
    - `confidence` string
    - `lenz_score` integer, nullable
    - `url` string
    - `distance` number, required
