nRouter

What is nRouter?

nRouter is an LLM gateway that gives teams one API key and one bill for models from several providers. It exposes an OpenAI-compatible endpoint, so existing OpenAI SDK code works after changing the base URL and key. Requests pass through nRouter before reaching a provider, where it applies budgets, rate limits and guardrails for content safety, PII detection and prompt injection prevention. Sending nrouter/auto as the model lets it choose an eligible model for the task. Other tools include prompt templates with versioning, A/B testing, spend analytics, SSO, role-based access control and audit logging. Billing is pay-as-you-go, with credits starting at $5 and a 0% platform fee; usage is charged at list price for whichever model served the request, with no token markup. Enterprise agreements add custom limits, dedicated capacity and a custom SLA.

Use cases
