NEXUS AEGIS · Agentic Firewall · Compliance Gateway

The un-bypassable control plane
between autonomous agents and enterprise systems.

NEXUS AEGIS consolidates tool-call firewalling, hallucination bounding, continuous drift certification, lineage tracing, and dead-man-switch overrides into a single production gateway. Every request is compatible with x402 USDC settlement and deterministic policy enforcement inside the live AAAA-Nexus worker.

Core Endpoints

Four deterministic intercepts for enterprise agent traffic

AEGIS can be purchased as pay-per-call infrastructure, then expanded into monthly compliance, lineage, and override lanes for high-volume enterprise fleets.

In addition to the four primary gate endpoints above, AEGIS provides dedicated lineage recording and trace lookup services for audit and compliance workflows.

AEG-100
MCP-Sentinel
$0.008
POST /v1/aegis/mcp-proxy/execute
  • Prompt-injection screening before tool execution
  • G23 hardness gate against intent drift
  • Delegates to existing authorization and zero-trust handlers
AEG-101
Epistemic Router
$0.008
POST /v1/aegis/router/epistemic-bound
  • OpenAI-style response proxying with entropy gate
  • Blocks high-entropy or low-confidence generations
  • Uses the live inference stack, then enforces the bound
AEG-102
Sovereign Drift Monitor
$0.080
POST /v1/aegis/compliance/certify-epoch
  • 47-epoch certificate issuance against drift and EU AI Act checks
  • Signed certificate records persisted into the suite ledger
  • Enterprise certification lane starts at $5,000/mo

Request Lifecycle

Every AEGIS request follows the same deterministic path

Step 1

x402 and request hygiene

Requests arrive with `X-API-Key` or a paid x402 proof. AEGIS also rejects quarantined heuristic or speculative control parameters before executing business logic.

Step 2

Deterministic guardrail evaluation

The suite fans into the existing platform primitives: prompt injection scan, threat scoring, authorization, zero-trust, drift guard, lineage, and audit logging.

Step 3

Suite envelope and audit trail

Responses are wrapped in an AEGIS envelope with formal bounds, pricing metadata, and auditable event records suitable for enterprise integration reviews.

Quickstart
curl -X POST https://atomadic.tech/v1/aegis/mcp-proxy/execute \
  -H "X-API-Key: an_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "agent_id":"324",
    "tool":"crm.write",
    "action":"create_ticket",
    "capability":"customer-support",
    "reference_intent":"create customer support ticket",
    "prompt":"Create a customer support ticket for order 9981."
  }'

Production AEGIS traffic may be settled through x402 USDC rails or standard API key authorization, depending on your enterprise contract.


Audit Lineage

Ledger-backed lineage and trace for every enterprise flow

AEGIS includes audit record services that persist lineage events and make them traceable by ID, so compliance reviews and incident investigations can be linked to real calls.

AEG-103 / AEG-104
Lineage Record & Trace
$0.060 / $0.020
POST /v1/aegis/lineage/record · GET /v1/aegis/lineage/trace/{id}
  • Record every decision lineage event into the suite ledger
  • Trace past requests by lineage ID during audits
  • Supports enterprise evidence chains and incident forensics

Commercial Packaging

Start as an API. Expand into an enterprise control perimeter.

AEGIS ships live today as routable API infrastructure, with monthly suite lanes for organizations that need certification and override operations at scale.

Production Ready

AEGIS is now a first-class storefront and API surface.

The suite is live in routing, pricing manifests, shared navigation, and the enterprise control-plane narrative on the homepage. If you want the next move, the cleanest follow-on is adding dedicated monitoring dashboards and richer enterprise onboarding around the existing endpoints.
