The Universal
Verification Engine

The core of the Xybern Control Plane. Every AI output, from any model, any agent, any format, is decomposed into claims, mapped to evidence, and scored deterministically.

Verification Engine Interface

The Core Stack

Three pillars of the verification engine.

Claim Decomposition

Every AI output is broken into individual, verifiable claims. Each claim is independently scored against source evidence, no black-box assessments.

  • Statement-level decomposition
  • Evidence mapping per claim
  • Hallucination detection

Provenance Vault

An immutable records layer that tracks every data access and reasoning step. Every output is anchored to original evidence, not model training data.

  • Source-to-claim mapping
  • Immutable audit trail
  • Regulatory-ready lineage

Deterministic Scoring

Zero LLM variance. Our proprietary scoring model produces identical results for identical inputs. Every score is reproducible, auditable, and permanently recorded.

  • Reproducible trust scores
  • Confidence intervals
  • Vault-recorded methodology
API Integration

One Endpoint.
Any Model.

Send any AI output to POST /api/v1/verify and get back a deterministic trust score, claim-level breakdown, and a permanent vault record.

Single Integration

One API call covers verification, governance, and vault recording. No orchestration needed.

Structured Response

Every response includes trust score, individual claims, evidence mapping, and governance outcome.

Enterprise Auth

Scoped API keys with workspace isolation, rate limiting, and full access logging.

Security from the Metal Up

The Verification Engine is built for enterprise AI infrastructure where governance is mandatory. Every verification is cryptographically anchored and fully auditable.

Security Architecture
SOC 2 Compliant

SOC 2 Type II

Rigorous external auditing of all security controls.

RBAC & SSO

Enterprise identity and granular access logs.

Data Isolation

Strict logical separation of customer environments.

Immutable Logs

Every data touchpoint recorded in the Vault.
