import Serixo from '@serixo/sdk';

const serixo = new Serixo({

// Score any transaction in one call
const result = await serixo.score({

  amount:    240,
  currency: 'EUR',
  ip:       req.ip,

// One field — done
if (result.action === 'block') {
  return res.status(402).json({ error: 'blocked' });
}
Architecture

Built for production.

Every technical decision made with scale, reliability, and security in mind — so you dont have to.

REST API · JSON

Standard HTTP with JSON payloads. Works with any language, any stack. No proprietary protocol, no binary formats.

OpenAPI 3.0 spec

mTLS + signed payloads

All API calls authenticated via API key + optional mTLS. Webhook payloads HMAC-signed so you can verify origin.

HMAC-SHA256

Multi-region · EU-first

Primary infrastructure in Frankfurt and Amsterdam. EU data residency by default. GDPR-compliant data processing.

EU data residency

Async webhooks

Real-time event delivery via webhooks with automatic retries and dead-letter queue. No polling needed.

at-least-once delivery

Zero data retention

Raw card data never stored. Transaction metadata retained for 90 days by default, configurable to 30. Reduces your PCI DSS scope.

PCI DSS SAQ-A

ML model auto-updates

Models retrain on fresh fraud signals weekly. You get accuracy improvements automatically — no redeploy, no action required.
