Enterprise AI gateway: one endpoint, every model, your policies

Point ChatGPT clients, Claude Code, Cursor, internal apps and agents at a single corporate endpoint. Keep the tools people already use; add identity, policy, routing and cost control underneath.

Without a gateway, every team integrates with providers on its own: personal API keys in shell profiles, shared keys in config files, no record of who used what. Costs are invisible until the invoice arrives and nobody can answer basic audit questions.

Rexaris AI exposes the OpenAI and Anthropic APIs on an endpoint inside your network. Requests carry user, group or application identity, go through classification and policy, and are routed to the provider or internal model your rules allow. Nothing about the developer or employee workflow changes except the base URL.

Why a gateway, not a policy document

  • Identity on every request

    Requests are tied to people, teams, applications and agents rather than to a shared key, so limits and audit are meaningful.

  • Bring your own keys

    Provider credentials stay with you. Rexaris AI uses your OpenAI, Anthropic and internal endpoints; there is no vendor account in the path.

  • Routing without retraining users

    Confidential requests can be answered by an internal Qwen or Llama while public ones go to an external provider, transparently to the caller.

  • Budgets and FinOps

    Spend per user, department, application, agent and model, with limits and alerts before the bill.

What the gateway gives you on day one

  • Compatible APIs

    OpenAI and Anthropic request formats; Claude Code, Cursor and most SDKs work by changing the base URL.

  • Classification and policy

    Every request is inspected and matched against deterministic rules before it is forwarded.

  • Model routing

    Per data class, user, group, application or provider.

Frequently asked questions

Which clients work with the gateway?
Anything that speaks the OpenAI or Anthropic API: Claude Code, Cursor, the official SDKs, LangChain-style frameworks and internal applications. The change is the base URL and a corporate credential.
Can I connect self-hosted models?
Yes. Qwen, Llama, vLLM, Ollama or any OpenAI-compatible endpoint can be registered as a destination and used in routing rules.
Do you store prompts?
The gateway stores what your audit policy asks for, in your database. Prompts never leave your infrastructure for ours.
How does it relate to a cloud AI gateway product?
Cloud gateways sit in the provider's cloud and focus on model access. Rexaris AI runs on-prem and focuses on data policy, classification and governance for regulated environments.
