# Public session logo bytes

> Serves the session's COPIED logo (always image/png after the upload re-encode). UNIFORM 404 with the same body when the session is unknown OR has no logo, not an existence oracle. On hit: `ETag: "<asset_id>"` and `Cache-Control: public, max-age=31536000, immutable` (safe because a replacement upload mints a new asset id and consumer URLs carry `?v=<asset_id>`).

  title: Minerva IDV API
  version: 1.0.0-draft
  description: >-
    Customer API for identity verification. Create verification sessions for
    profiles, deliver invites, track capture progress, and read review outcomes.
    For the end-to-end flow, see the [IDV Integration
    Guide](/api-reference/idv-integration-guide). Reviewer-safe responses never
    expose storage keys, checksums, wrapped keys, encryption context, raw OCR,
    or raw model output. Decrypted personal data is available only on `GET
    /sessions/{sessionId}/data`, to an authenticated in-scope principal, with
    fail-closed auditing.
