The platform

Everything between your product and the models.

AiGate consolidates access, routing, observability and billing into one dependable control plane—without changing how your team builds.

Unified model API

Use familiar OpenAI-compatible endpoints across chat, Responses, vision, embeddings and realtime experiences.

SmartRoute 2.0

Continuously ranks eligible upstream routes using success rate, latency, cost, margin, budget and current load.

Intelligent caching

Reuse deterministic results at the gateway, reduce upstream latency and pass cached-token savings into precise settlement.

Transparent billing

Estimate before a request, reserve safely, settle on actual usage and preserve immutable price and cost snapshots.

Enterprise access control

Scope API keys by model, endpoint, IP/CIDR, quota, concurrency and expiry—with secure rotation and full auditability.

Operational visibility

Trace every request through routing decisions, upstream attempts, token usage, latency, settlement and profit.

For developers

Switch models without rebuilding your stack.

Point your existing client to AiGate, keep your request format and select the model you need. Routing, limits, settlement and observability happen behind the same stable endpoint.

For business

Turn AI infrastructure into a controlled, profitable service.

Set pricing by customer group, control procurement budgets and reconcile every balance movement with auditable evidence.

Protect every margin

Separate platform selling prices from upstream purchase cost. Freeze both snapshots per request and analyze real profit by model, channel and customer.

Operate with confidence

Health checks, circuit breaking, route-risk SLAs, budget controls and automatic failover keep production traffic within policy.

FAQ

Start with one endpoint.

Everything you need to understand how AiGate fits into your product and operations.

What is AiGate?

AiGate is a multi-tenant AI API aggregation, intelligent routing and billing platform. It provides one compatible API in front of multiple model providers and adds access control, cost settlement, monitoring and failover.

Do I need to change my OpenAI client?

In most cases, you only change the base URL and API key. AiGate exposes OpenAI-compatible Chat Completions and related interfaces while enforcing the model and endpoint permissions assigned to your key.

How does SmartRoute 2.0 choose an upstream route?

SmartRoute evaluates routes that are healthy and allowed, then scores them using success rate, latency, procurement cost, profit, available budget and current load. Safety controls and failover always remain active.

How is usage billed?

AiGate can reserve an estimated amount before forwarding a request and then settle against actual input, cached input and output token usage. Each request preserves its pricing and cost snapshot for later reconciliation.

Can I restrict an API key?

Yes. Keys can be limited by model, endpoint, source IP or CIDR, quota, RPM, TPM, concurrency and expiry. Rotation and revocation preserve historical audit and billing records.
