# Authenticity score (cached, daily) for one KOL

`GET /api/kols/{username}/authenticity`

## Request

- Base URL: `https://api.kolens.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.kolens.ai/api/kols/{username}/authenticity`
- Auth: HTTP bearer

Return the composite authenticity score + per-signal breakdown.

Cached daily per (username, platform, ALGORITHM_VERSION). The
first call of the day computes and persists; subsequent calls
return the cached row instantly.

Returns 404 only when the author doesn't exist in our DB at all.
Accounts that exist but lack data return a row with
``confidence='insufficient_data'`` — caller renders a grey badge.

## Path parameters

- `username` string, required

## Query parameters

- `platform` string: Platform identifier
- `refresh` boolean: If true, recompute even if a same-day cache row exists.

## Response `200`

Successful Response

- AuthenticityScoreOut: Composite authenticity score + per-signal breakdown. Note on copy: every user-visible string here says "authenticity" or "signal" — never "fake" / "bot" / "fraud". The PM revision is firm on this: the score lives in legal grey area and the wording is the cover.
