Quick start

from voiceidvault import VoiceIDVaultClient

client = VoiceIDVaultClient(api_key="your-api-key")

# ── 1. Enroll a new user ──────────────────────────────────────────────────────
session = client.init_enrollment("user-123", "+12125551234")

# User receives an SMS — collect the code and verify
sms_result = client.verify_sms_otp(session.session_id, "user-123", "654321")
print("SMS verified:", sms_result.verified, "next step:", sms_result.next_step)

# Enroll face
with open("face.jpg", "rb") as f:
    face_result = client.enroll_face(session.session_id, "user-123", f.read())
print("Face enrolled, liveness score:", face_result.liveness_score)

# Enroll voice
with open("voice.wav", "rb") as f:
    voice_result = client.enroll_voice(
        session.session_id, "user-123", f.read(),
        phrase="my voice is my password",
        duration=5,
    )
print("Voice quality score:", voice_result.quality_score)

# Complete enrollment
result = client.complete_enrollment(session.session_id, "user-123")
print("Vault ID:", result.vault_id)
print("Trust score:", result.trust_score)

# ── 2. Authenticate ───────────────────────────────────────────────────────────
with open("voice.wav", "rb") as f:
    auth = client.authenticate_voice(
        f.read(),
        user_id="user-123",        # optional — omit for open-set search
        confidence_threshold=0.85,
    )

if auth.verified:
    print("Authenticated! Confidence:", auth.confidence)
    print("Identity:", auth.identity.user_id if auth.identity else "unknown")
else:
    analysis = auth.deepfake_analysis
    if analysis and not analysis.passed:
        print("Deepfake detected, confidence:", analysis.confidence)

# ── 3. GDPR right-to-erasure ──────────────────────────────────────────────────
deletion = client.request_deletion("erasure", reason="Account closure")

with VoiceIDVaultClient(api_key="your-api-key") as client:
