Built by developers,
for developers.
FaceVault exists because we got tired of identity verification APIs that cost a fortune, take weeks to integrate, and treat developers like an afterthought.
The problem
KYC verification is broken. The incumbents charge $2–5 per check, lock you into annual contracts, and hand you a 200-page integration guide written by someone who has never shipped a product. Need to test in sandbox? Fill out a sales form. Want to see the API? Sign an NDA.
We’ve been on the other side of that table. We’ve waited three weeks for API credentials, debugged opaque error codes with no documentation, and paid enterprise prices for what amounts to a wrapper around open-source models. So we built the thing we wished existed.
Our approach
Open AI pipeline
MediaPipe for face detection (478 landmarks). ArcFace for face matching (512-dimensional embeddings). OpenCV for document processing. Every model is open-source or published research — no proprietary black boxes.
API-first, always
Four endpoints. JSON in, JSON out. Full OpenAPI spec with Swagger UI. Postman collection included. You can go from zero to a working integration in 10 minutes — we timed it.
Transparent pricing
From $0.99 per check on Starter, dropping to $0.35 at volume. No annual contracts. 50 free checks per month to get started. The price is on the website because we’re not embarrassed by it.
No sales calls
Sign up, get an API key, start verifying. If you need help, email us. We don’t have a “Book a Demo” button because the demo is the API documentation.

What we believe
Transparency
Every model we use is open-source or published research. No black boxes, no mystery scores. You can read the papers yourself.
Developer Experience
Four API calls. Ten minutes to integrate. Real documentation with real code examples — not a 40-page PDF with screenshots of a dashboard.
Privacy-First
Photos are processed and discarded. We don't build facial recognition databases. Your users' biometric data is not our business model.
Fair Pricing
From $0.35 per check at volume, $0.99 on Starter. No annual contracts, no surprise invoices. Start free, pay as you scale.
Open models, open research
Every AI model in the FaceVault pipeline is either open-source or based on peer-reviewed published research. We didn’t train a proprietary model and slap a “trust us” label on it.
