AI Gateway

The control plane for autonomous AI agents.

OpenAI-compatible LLM routing, real-time guardrails, immutable audit trails, and built-in NIST AI RMF, AIUC-1, and FedRAMP-ready controls. Every agent decision governed, observable and compliant.

What it is

Every agent call routes through the AI Gateway

STRUCTURA's agents don't call LLM providers directly. They call the AI Gateway, which enforces guardrails, logs every interaction to an immutable audit store, and routes to the underlying provider (Anthropic, OpenAI, AWS Bedrock) based on your policy.

That one architectural decision is what makes autonomous agents safe to run in production. Without a gateway, you have a pile of agents calling external APIs with no governance, no audit trail, and no way to prove what happened when the auditor asks. With it, every agent action is a policy decision you can defend.

How it works

Query → Route → Inspect → Approve

Every agent request follows the same governed path. The AI Gateway receives the query, routes to the best provider, inspects the response against your guardrails, and logs the full exchange to an immutable audit trail.

How it works

01 / 04

Agent sends query

An agent submits a request to the AI Gateway. The gateway receives the prompt, validates the API key, resolves tenant-scoped guardrails, and begins the routing decision.

02 / 04

Gateway selects provider

Based on your routing policy, the gateway evaluates model aliases, cost budgets, and provider health to route the request to the optimal LLM — Claude, GPT, Llama, or Gemini.

03 / 04

Response inspected

The selected provider processes the request and returns a response. The gateway inspects the output against content filters, schema compliance, and hallucination detection rules.

04 / 04

Approved & logged

The response passes all guardrails and is delivered to the agent. Every step — request, routing decision, response, and policy check — is logged to the immutable audit trail.

Compliance built in

Designed for regulated AI from day one

Most LLM tools were built for experimentation and retrofitted for compliance. The AI Gateway was designed around the inverse: start with the audit, observability, and control requirements, then build the routing layer on top. If you need to prove your AI system is governed, you start from evidence, not justifications.

NIST AI RMF

Continuous evidence across the Govern, Map, Measure, and Manage functions. Every agent decision is traceable to a specific policy and outcome.

AIUC-1

Full control coverage across A001-E012, with pre-built evidence exports for independent assessors.

FedRAMP-ready

OSCAL-formatted control documentation and immutable audit logging designed for high-impact authorization boundaries.

EU AI Act

Risk categorization, human-oversight logging, and transparency records that map to high-risk AI system requirements.

Evidence you can export

OSCAL-formatted control documentation. Immutable audit logs with tamper-evident signatures. Pre-built evidence exports for NIST AI RMF, AIUC-1, and FedRAMP authorization packages. Your auditor's job becomes reading evidence, not chasing it.

Core capabilities

Everything a production AI control plane needs

OpenAI-compatible LLM routing

Drop-in replacement for the OpenAI API. Route across Anthropic, OpenAI, AWS Bedrock, and Vercel AI Gateway with model aliasing, fallback, and provider-failure isolation.

Real-time guardrail enforcement

In-flight inspection for content filtering, token budgets, rate limits, tool restrictions, hallucination detection, schema compliance, and LLM-evaluated custom policies.

Immutable audit trail

Every request, response, tool call, and decision logged to NATS JetStream and PostgreSQL. Designed to survive audit scrutiny for FedRAMP, AIUC-1, and NIST AI RMF.

Tenant-scoped governance

Per-tenant API keys, guardrail rules, rate limits, spend caps, and audit isolation. Multi-tenant safety at the database and query level.

Cost tracking and spend control

Per-token billing, per-team daily caps, and quota alerts. Langfuse integration for extended analytics on every agent run.

Model Context Protocol (MCP)

Every service exposes an MCP server. Agents can inspect rules, models, and usage as first-class context - not opaque calls.

Agent-to-agent (A2A) delegation

Agents delegate work to other agents with async task management and Redis-backed state, fully audited end-to-end.

OpenTelemetry + Langfuse observability

OTEL traces, Langfuse LLM analytics, and ClickHouse trace warehousing give you a single pane for every agent decision.

Relationship to the six agents

The nervous system of autonomous cloud operations

The AI Gateway isn't a separate product. It's the control plane that makes every agent's decisions safe, observable, and compliant. When the Terraform Agent reviews a plan, the Gateway logs the evidence. When the Security Agent flags a CIS violation, the Gateway records the policy check. When the Orchestrator sequences a multi-cloud deploy, every agent-to-agent call passes through the Gateway's A2A layer.

Built on open standards and proven infrastructure

The AI Gateway uses the Model Context Protocol, OpenTelemetry, and OSCAL - plus battle-tested open-source infrastructure for every layer of the stack.
