How accurate is the face recognition?

Accuracy depends on image quality and lighting, but SIMSIM uses modern deep-learning models tuned for high precision and low false-match rates in production conditions.

Why SIMSIM

One face recognition API,
engineered for production.

We handle the formats, the models, and the infrastructure — so you send a request and get a clean, reliable answer back.

Templates, not photos

We store neural-network templates that can't be reversed into an image. Your users' pictures never sit on our servers.

Every language, ready

Any language that speaks HTTP can call SIMSIM. Copy-paste examples cover the stacks teams reach for most.

Recognition in ~60ms

High-CPU cloud nodes keep every endpoint fast under load, so recognition returns in about 60 milliseconds.

Predictable pricing

Flat monthly plans with clear request limits. No surprise metering, no per-call math to reconcile at month end.

Scales with you

Process a handful of photos or millions. Capacity grows with your traffic without you re-architecting anything.

Turnkey endpoints

The hard use cases are already built. Send a request, get a structured response — no models or memory to manage.

Single platform

Recognition, liveness, detection
& attributes — one logic.

Everything you need to build on faces, sharing the same predictable request and response shape across every endpoint.

FAQ

Questions, answered.

How do I try the SIMSIM Face API?

Create a free account, choose your language, and follow the quickstart. Every account includes 250 requests per month at no cost, with no credit card required.

Do the plans include all API features?

Yes. Every plan unlocks the full API — detection, comparison, verification, liveness, and attribute analysis. Plans differ only in monthly requests, throughput, and stored face templates.

What are the common use cases?

KYC and onboarding, access control, fraud and account-sharing prevention, age verification, retail analytics, and personalization — across fintech, iGaming, crypto, and payments.

Is facial recognition accurate?

Accuracy depends on image quality, lighting, and your reference set, but modern deep-learning models — like the ones SIMSIM runs — are highly accurate in production conditions.

How is my data stored?

SIMSIM stores mathematical face templates, not photos. Templates can't be reversed into an image, so your users' pictures are never retained on our servers.

Is facial recognition legal where I operate?

It's permitted in many jurisdictions, with limits in some. Always check the specific laws and consent requirements that apply to your users before deploying.
