# R9S > R9S, also called RouteTokens, is a distributed AI gateway for production model traffic. It provides one access layer for multiple model families, provider routes, observability, fallback, and spend visibility. ## Useful Facts - Website: https://r9s.ai/ - Gateway base URL: https://gw.r9s.ai/v1 - API style: OpenAI-compatible gateway endpoints with custom base URL support. - Support: support@r9s.ai ## Primary Pages - [R9S Home](https://r9s.ai/): Product overview for the R9S distributed AI gateway, OpenAI-compatible access, routing, observability, and pricing entry points. - [Models and Pricing](https://r9s.ai/models/): Supported open model families, input/output pricing, cached-input pricing, and model selection information. - [Documentation Overview](https://r9s.ai/docs/overview/): Start point for R9S setup, gateway concepts, API references, operations, and agent integrations. ## Documentation - [Quick Start](https://r9s.ai/docs/getting-started/): Send the first request through the R9S distributed AI gateway. - [Core Concepts](https://r9s.ai/docs/concepts/): Understand the gateway and model identifiers used by R9S. - [API Reference](https://r9s.ai/docs/api-reference/): Base URLs, authentication, headers, endpoint families, and response conventions for the R9S gateway API. - [Chat Completions](https://r9s.ai/docs/chat-completions/): Create chat completions through the R9S OpenAI-compatible gateway endpoint. - [Responses API](https://r9s.ai/docs/responses-api/): Use the R9S Responses endpoint for instruction-based, tool-capable, and stateful model calls. - [Models](https://r9s.ai/docs/models/): List available models and retrieve model metadata through R9S. - [Agent Integrations](https://r9s.ai/docs/agent-integrations/): Configure coding agents and tools to use R9S as their model gateway. - [Monitoring and Operations](https://r9s.ai/docs/monitoring-operations/): Track R9S request volume, latency, errors, logs, usage, and cost across gateway traffic. - [Best Practices](https://r9s.ai/docs/best-practices/): Practical guidance for secure, reliable, and cost-aware R9S gateway integrations. - [Production Rollout](https://r9s.ai/docs/operations/): Move an R9S gateway integration from trial traffic to production safely. ## Legal - [Privacy Policy](https://r9s.ai/privacy/): R9S Privacy Policy - [Terms of Service](https://r9s.ai/terms/): R9S Terms of Service
