Getting Started with EVE AI Core

Integrate deterministic governance enforcement into your AI pipeline. Verify every output before it reaches your users.

What EVE AI Core Does

EVE AI Core is a governance enforcement platform for AI outputs. It sits between your AI model and your end users, applying deterministic safety rules, scoring output integrity, and blocking harmful or non-compliant content before it ships.

Every AI output routed through EVE is evaluated against a configurable set of charter rules, scored using Calibrated Reliability Diagnostics (CRD), and either approved, flagged, or blocked. The platform provides cryptographic audit trails, circuit breaker protection against provider failures, and a truth store for grounding factual claims.

EVE does not modify your AI outputs. It verifies them. If an output fails governance checks, your application receives a structured verdict explaining what failed and why, so you can take the appropriate action.

Core principle: Governance decisions are deterministic. The same input and rule set always produce the same verdict. No probabilistic filtering, no hidden model-based overrides.

Review the API Documentation

The API reference covers authentication, endpoint specifications, request/response formats, error codes, and rate limits. All governance endpoints return structured JSON verdicts with full audit metadata.

Install the SDK

Official SDKs are available for Python (eve-coreguard) and Node.js (eve-ai-governance), both with zero heavy dependencies. Any other stack can call the REST endpoint directly.

# Python
pip install eve-coreguard

# Node.js
npm install eve-ai-governance

# Any language: call the REST API directly
POST https://api.eveaicore.com/v1/decisions/evaluate

Quick Integration Example

The following Python example shows a minimal integration. Obtain your API key from the developer console after your license is provisioned. evaluate() takes keyword arguments directly — there is no request object to construct.

from eve_coreguard import CoreGuardClient

# Initialize with your API key
client = CoreGuardClient(api_key="eve_sk_...")

# Evaluate a proposed decision before it is acted on
result = client.evaluate(
    tenant_id="bank_001",
    proposed_action={"type": "loan_approval", "amount": 250000},
    model_output={"decision": "approve", "confidence": 0.91},
    context={"credit_score": 580, "debt_to_income": 0.52},
    policy_set="lending_v1",
)

# Act on the verdict: ALLOWED | BLOCKED | MODIFIED
if result.blocked:
    # result.policy_violations explains every rule that fired
    use_safe_alternative()
else:
    # result.decision_id + result.signature = the signed certificate
    proceed(result.verdict)
Every decision is a signed certificate. Each evaluation returns an HMAC-SHA256 signed Decision Certificate (result.decision_id, result.signature, result.audit_hash) that your controls team can verify independently — offline, with no call back to EVE. Governance verification adds single-digit milliseconds to your pipeline.

Key Concepts

CRD Scoring

Calibrated Reliability Diagnostics (CRD) is the composite integrity score assigned to every AI output. CRD evaluates factual grounding, charter compliance, hallucination risk, and uncertainty calibration. Scores range from 0 to 100. Outputs below your configured threshold are automatically flagged or blocked.

Charter Rules

Charter rules are the deterministic governance constraints applied to every output. EVE ships with 15 immutable rules covering safety, identity integrity, non-harm, and truthfulness. These cannot be weakened. Enterprise customers can add custom rules that impose additional restrictions on top of the immutable set.

Circuit Breaker

The circuit breaker monitors upstream AI provider health. When a provider begins failing (consecutive errors, latency spikes, rate limit exhaustion), the circuit breaker opens and routes traffic to fallback providers or returns a structured degradation response. This prevents cascading failures in your production pipeline.

Truth Store

The truth store is a curated, versioned repository of verified facts used to ground AI outputs. When an output makes a factual claim, the governance pipeline checks it against the truth store. Claims that contradict verified facts are flagged with specific correction metadata. Enterprise customers can populate the truth store with domain-specific ground truths.

Enterprise Licensing

EVE AI Core is licensed on an annual basis. Most engagements start with a fixed-fee Design Partner Pilot — proving enforcement on your own decision logs — then convert to a production license. See the full pricing page for current details.

Design Partner Pilot

$37,500 (60-day)

Sandbox pilot that proves enforcement on your own decision logs — single tenant, one policy pack, no production data required. The pilot fee is credited toward your first annual license.

CoreGuard Enterprise

From $125,000/year

Production enforcement for a regulated workflow. Published governed-decision bands from 1M/year (up to 5 models, $125K) to 10M/year ($270K), full EVE Proof evidence, 3-year retention with open export, and a 99.5% uptime SLA with a 24/7 sev-1 path.

Enterprise Governance

Contact Sales

Multi-workflow governance across teams with tenant isolation. Custom decision volumes, 7-year retention, on-premise deployment option, and a 99.9% uptime SLA.

Sovereign Infrastructure

Contact Sales

For Tier-1 banks, large insurers, and defense. Any deployment including air-gapped, unlimited governed decisions, white-label attestation, and a custom negotiated SLA.

Assessment first: All engagements begin with a governance assessment to scope integration requirements, compliance needs, and deployment architecture. Contact the governance team to schedule.
