### List enrolled voiceprints

<Note>
  `GET /api/v1/verify/voice-biometrics/`
</Note>

Cursor-paginated list of voiceprints for this tenant. Returns metadata only — no embedding bytes.

<RequestExample>
  <CodeGroup>
    ```bash cURL theme={null}
    curl -X GET "https://api.orbit.devotel.io/api/v1/verify/voice-biometrics/" \
      -H "X-API-Key: dv_live_sk_your_key_here"

### Get voiceprint enrollment status

<Note>
  `GET /api/v1/verify/voice-biometrics/enroll/{id}`
</Note>

Returns the enrollment status of a single voiceprint by id (the id returned by POST /enroll). Response shape is `{ id, status, voiceprint_id, confidence? }`. Enrollment is synchronous, so a known id reports `enrolled` while an unknown or GDPR-erased id returns 404.

<ParamField path="id" type="string" required>
  The voiceprint id to look up (the `vp_`-prefixed id returned by `POST /enroll`). Returns `404` if the id is unknown or its voiceprint was erased.
</ParamField>

<RequestExample>

### Issue a verification challenge nonce

<Note>
  `POST /api/v1/verify/voice-biometrics/challenge`
</Note>

Issues a per-attempt liveness/replay-resist challenge phrase. The caller reads the returned `phrase` aloud, records the audio, and submits both the audio AND the nonceId+phrase on the next `POST /verify`. The verify path one-shot-consumes the nonce and rejects on missing/expired/reused/mismatched values, defeating recorded-voice replay attacks. 5-minute TTL.

<RequestExample>
  <CodeGroup>
    ```bash cURL theme={null}

### Enroll a voiceprint

<Note>
  `POST /api/v1/verify/voice-biometrics/enroll`
</Note>

Upload a WAV audio clip (base64) to enroll a new voiceprint for a contactId. Requires explicit GDPR Art. 9 consent. Rejected if anti-spoof score is below threshold. Returns a 429 with top-level `code` `RATE_LIMIT_EXCEEDED` and `details.reason` `voiceprint_tenant_cap_exceeded` if the tenant has reached its `voice_biometrics.tenant_enroll_cap` quota.

### Update voice biometrics tenant settings

<Note>
  `PATCH /api/v1/verify/voice-biometrics/settings`
</Note>

Persist the per-tenant confidence threshold (0.50 permissive → 0.95 strict — governs the cosine-similarity gate on POST /verify) and the auto-escalate-to-2FA-on-low-confidence intent flag. Both values round-trip via GET /overview.

Both fields are required — send the full pair on every request.

<ParamField body="confidence_threshold" type="number" required>
  The cosine-similarity gate a verification must clear to pass, between `0.50` (most permissive) and `0.95` (most strict). Values outside this range are rejected.
</ParamField>

<ParamField body="auto_2fa_on_low_confidence" type="boolean" required>
  When `true`, a verification that falls below the threshold signals downstream step-up flows to escalate to a second factor instead of returning a hard fail.
</ParamField>

<RequestExample>
  <CodeGroup>
    ```bash cURL theme={null}

### Delete a voiceprint (GDPR erasure)

<Note>
  `DELETE /api/v1/verify/voice-biometrics/{voiceprintId}`
</Note>

Permanently deletes a voiceprint and its encrypted embedding. GDPR Article 17 right-to-erasure. This is a real DELETE (not a soft-delete), so the record leaves no trace once removed.

<Note>
  This endpoint is **not** idempotent. A successful delete returns `{ "deleted": true }`. Because the row is erased outright, a second `DELETE` of the same `voiceprintId` — including a client retry after a network timeout — returns `404 Not Found`, the same as deleting an unknown id. Treat a `404` on retry as confirmation the voiceprint is already gone.
</Note>
