import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.meridianblue.ai/v1 ⁠',

});

Safety and compliance built into every request.

Six clear controls that turn your LLM gateway into an audit-ready layer for the EU AI Act, GDPR, and industry regulations.

EU AI Act Risk Classification

Every request scored minimal, limited, high, or prohibited before routing. Article 5 detectors block prohibited practices at the gateway with structured rejections.

Signed Audit Evidence

WORM forensic vault with Merkle-chained logs, signed compliance envelopes on every response, and one-click regulator export. Tampering is mathematically detectable.

Data Residency Enforcement

One toggle keeps traffic on EU-resident infrastructure. Per-member-state profiles for HDS, BaFin, and ACN. Fallback that would cross the boundary fails instead of degrading silently.

Human Oversight Workflows

Article 14 enforcement at the gateway. Advisory, blocking, or dual-control review queues for high-risk requests, with reviewer literacy gating built in.

Deployer Policy Engine

Versioned, dual-signed tenant policies make every compliance behavior configurable. Liability lands where the AI Act places it — with you, not with us.

Resilience Without Risk Drift

Fallback chains across providers and regions, with mandatory risk re-validation on every failover. A request acceptable on Model A is re-classified before Model B sees it.
