About nRouter

nRouter functions as a secure gateway for enterprise LLM operations, offering a unified API endpoint that connects to multiple AI model providers. It consolidates billing, routing, and security controls under one key while maintaining transparent per-token pricing. The platform enforces hard spending limits at the organization, team, or API key level, preventing accidental overspending through pre-call credit reservation. AI security features such as PII redaction, prompt injection detection, and content safety checks run inline on every request regardless of plan tier. The system supports real-time cost tracking with daily aggregates, allowing teams to monitor spending against usage before invoices arrive. Smart routing capabilities include fallback chains, weighted load balancing, and model aliases to optimize for cost, latency, or reliability across providers. Additional modules cover server-side prompt management with versioning and A/B testing, organization hierarchy with role-based access, and observability through request logs and integrations with monitoring tools.
