TECHNICAL DESIGN WORKSPACE

Integration Architecture

Area	Design responsibility
SDK architecture	Package reusable client and server integration components.
REST API	Expose stable transaction scoring, explanation and operational interfaces.
Event / webhook support	Allow asynchronous result delivery and system events where required.
Authentication	Strong machine and operator authentication.
Authorization	Role-, client- and scope-based access control.
API keys / OAuth	Support governed credentials appropriate to deployment context.
Request schemas	Define canonical transaction metadata contracts.
Response schemas	Return score, confidence, reasons, version and trace identifiers.
Trust-score endpoint	Primary real-time transaction trust scoring interface.
Batch scoring	Support historical or bulk validation workloads.
Explainability endpoint	Return authorized reasoning metadata and reason codes.
Health endpoint	Expose service liveness and readiness.
Audit endpoint	Allow authorized retrieval of trace and version metadata.
Rate limits	Protect service capacity and tenant fairness.
Error handling	Standardize validation, authentication, dependency and model errors.
Sandbox	Provide a non-production integration environment for operators.
Versioning	Maintain backward-compatible API and SDK evolution.
Deployment	Support containerized, cloud, hybrid or operator-hosted patterns as required.
