You.com Inference Router provides access to language models through OpenAI-compatible and Anthropic-compatible API endpoints, using one base URL and API key. Applications can list available models, send requests, and stream responses through either endpoint. Requests can also declare web-search or page-fetch tools, allowing the router to retrieve web information and return the sources used. The service supports existing OpenAI and Anthropic SDKs with a base-URL and credential change. You.com describes the product as serving production workloads with its own inference capacity and automatic failover to partner providers.
