Why nRouter

Access all major LLM providers through a unified API key, featuring enterprise budget controls, audit logging, guardrails, and multi-tenant isolation.

nRouter is the enterprise LLM gateway between your app and every major model provider — one OpenAI-compatible API with pre-call budget holds, in-path guardrails, and multi-tenant isolation at a 0% platform fee.

One key, one bill: Call OpenAI, Anthropic, Google Vertex AI, Azure Foundry, and Alibaba US with one NROUTER_API_KEY (Quick Start · Auth).
Spend you can trust: Pre-call reserve+settle billing at exact list prices (x-nr-request-cost), card fees absorbed, and org → team → key RPM/TPM and spend caps (Budgets).
Zero-spend guardrails: PII redaction, prompt-injection defense, and content moderation run in-path before the provider call — blocked requests spend $0 (Guardrails).
Strict isolation: Row-level tenant isolation, organization roles (owner, org_admin, member, viewer) plus team-scoped team_admin authority, CSV log exports, and Enterprise SSO + SCIM (Organizations · Teams).
