Instant verdict
Score 0–100, verdict, and the exact signals behind it. Explainable by design.
Why not Stripe Radar?
Stripe sees payments.
We see everything else.
Stripe Radar only works inside Stripe and only on card transactions. Fraud happens long before any payment starts.
Integration
Works with any stack.
One REST endpoint. No SDK. No agent. No contract. Copy, paste, ship in 30 minutes.
// Install: no SDK needed — just fetch
const res = await fetch('https://kairoscheck.net/api/check', {
method: 'POST',
headers: {
'Authorization': 'Bearer kc_live_<your-key>',
'Content-Type': 'application/json',
},
body: JSON.stringify({ domain: 'suspicious-shop.io' }),
});
const { verdict, score, signals } = await res.json();
if (verdict === 'BLOCK') {
throw new Error('Signup denied — fraud detected');
}Transparent by design
