What the API returns

Every API call returns a structured JSON response: fraud score (0–1), confidence band (low/medium/high), top contributing signals with feature weights, webhook event type, and a decision reference ID that maps to the immutable audit log.

No post-processing required to satisfy EU AI Act Article 13 documentation requirements — the explainability data is in the response.

Standard deployments follow SENTR's documented 8-day integration timeline — with a dedicated integration engineer from kickoff through read-only validation.

EU data residency — GDPR Article 44 compliant by architecture

All transaction data processed by SENTR remains within EU data centres throughout shadow mode and full deployment. No cross-border data transfer occurs — GDPR Article 44 compliance is architectural, not a configuration option. SOC 2 Type II certification covers the full data processing pipeline.

Regulatory-ready audit log — on demand

Immutable audit trail

Every automated decision is written to an immutable log at decision time. The decision reference ID returned in the API response maps directly to the full log record — traceable from score to outcome.

On-demand export

Full audit log exportable in structured format for regulatory submissions. Export is available in under 45 minutes from request to delivery — one click, no manual reconstruction.

Decision reference traceability

Every fraud case in the Investigation Hub traces back to individual decision reference IDs. The regulatory chain of evidence is complete — from score to outcome to human review to dispute resolution.
