The problem
A new SIM, a fresh email and a reapplication — text-only KYC can't tell a repeat fraudster from a first-time borrower.
Slow vendor round-trips and repeated selfie retries push borrowers to abandon onboarding — often at the last step before disbursal.
One for face match, one for liveness, one for sanctions, one for KYB — four contracts, four dashboards and four points of failure in a single loan journey.
Neetix Liveliness puts every one of these checks behind one API key — one integration, one audit log, one bill.
Platform
Face, liveness, documents, sanctions, business identity and device risk — every check behind one API key, one ledger and one audit log.
1:1 verification on ArcFace 512-d embeddings with calibrated cosine scoring. Every response is Ed25519-signed so downstream systems can verify it.
512-d embeddings · ArcFace
Passive single-frame anti-spoof, active head-pose and blink challenges, and continuous V-CIP video over WebSocket.
passive · active · V-CIP
Name screening against consolidated OFAC and UN entries, with KYT transaction monitoring and crypto wallet screening on the same key.
Score device and IP risk alongside every identity check, so risky sessions surface before the decision — not after disbursal.
Validate GSTIN, PAN and CIN for business onboarding, and parse passport MRZ per ICAO 9303 — same API, same audit log.
Search each new applicant against every face you've seen. Duplicate and blocklist galleries stop reloan fraud at the door.
Outcomes
Run face match, liveness and screening in a single request instead of chaining vendors. Fewer hops, fewer places for applicants to drop off.

Every applicant is searched against your duplicate and blocklist galleries — a new SIM and a fresh email don't make a new person.

Verify a responseSDKs
REST is stable today. Native SDKs for web, mobile and cross-platform are in pre-release — same contract, same signed responses.
Architecture
Every verification follows the same path — authenticated, metered, scored by the engines you choose, and returned as one signed verdict. Under 200ms per check self-hosted; about 0.7s for a face match on the shared cloud tier.

One Rust binary plus Postgres, on your VM.
Security
No badge wall — six specific guarantees, stated precisely, because the details are the security.
Every call to the managed API travels over TLS. Keys, selfies and results are never sent in plaintext.
Your key is shown once at signup and stored only as a SHA-256 hash. The plaintext never touches our disk.
Every verdict is signed with Ed25519. Fetch the public key at GET /v1/verification-key and verify results offline.
Each API call writes an audit entry — endpoint, outcome and credits spent — so any decision can be reconstructed later.
1:N search, duplicate and blocklist galleries are scoped to your tenant. There is no cross-tenant query path.
Selfies and documents are held in memory only for the duration of the check, and are not retained by default.
Designed for India's DPDP Act: your organisation is the data fiduciary, and Neetix acts as the processor — on your instruction only.
V-CIP video streaming, active challenges and per-request audit trails are designed to fit RBI Digital KYC flows.
Anti-spoof models are exercised against iBeta-style PAD protocols internally — not a certification claim. Security documentation available on request.
Industries
Every scenario below runs on the same checks and the same prepaid credits — pick an industry to see a real flow.
V-CIP account opening: an agent joins a live video stream over WebSocket while liveness and face match run continuously against the applicant's ID photo — the pattern RBI Digital KYC flows expect.
Checks in this flow
V-CIP account opening: an agent joins a live video stream over WebSocket while liveness and face match run continuously against the applicant's ID photo — the pattern RBI Digital KYC flows expect.
Wallet onboarding without the queue: a single selfie is checked for liveness, matched against the document photo, and the user's ID fields are validated before the first transaction.
Loan origination: KYC the borrower with liveness and face match, validate the business's GSTIN and PAN, then search the 1:N gallery to catch repeat or blocklisted applicants before disbursal.
Policy issuance and claims: parse the ID document's machine-readable zone, confirm the claimant is a live person, match their selfie to the policyholder photo, and screen against sanctions lists.
Driver and worker identity: an active head-pose and blink challenge at signup, periodic re-verification selfies matched 1:1, and duplicate detection across the fleet's face gallery.
Exchange compliance: KYC with liveness and face match at signup, AML/PEP screening against 18,079 OFAC and UN entries, then KYT monitoring and wallet screening on every withdrawal.
Use case
Document, selfie, biometrics and sanctions — a complete KYC decision from a handful of API calls.
Field checks return in tens of milliseconds and a full face check in well under a second, so the whole chain feels like one screen — not a queue. Regulated teams get the same flow with an audit log entry for every request.
Call the steps individually, or let the workflow endpoint orchestrate the chain server-side (3 credits per run) and hand back one Ed25519-signed verdict.
The user photographs their passport or ID in your app.
Machine-readable zone parsed and checksum-validated per ICAO 9303.
A single selfie frame — no video upload required.
Passive single-frame anti-spoof check — no blink dance for the user.
Selfie matched 1:1 against the document photo — calibrated cosine over 512-d embeddings.
Name screened against 18,079 OFAC and UN sanctions and PEP entries.
One structured result you can verify against GET /v1/verification-key.
