Getting started
How do I send my first request? Follow the Quickstart — it takes you from sign-up to a traced LLM call. What’s the difference between an organization, a workspace, and a project? Everything nests into Organization → Workspace → Project. See Core Concepts. Do I need to change my application code? No. Point your SDK’s base URL at the gateway and authenticate to to11 with thex-to11-authorization header — your application logic stays the same. See Integrations.
Providers & integrations
Which SDKs are supported? The OpenAI, Anthropic, and Vercel AI SDKs. See Integrations. Which model providers can I use? OpenAI and Anthropic have native adapters. Many more work through the gateway as OpenAI-compatible providers (such as xAI, Mistral, and Groq) or as cloud platforms with their own auth (Azure OpenAI, Google Gemini, and AWS Bedrock). See Supported providers for the full list. Can I send a request in one format and route it to a different provider? Only to a provider that speaks the same format. The gateway forwards each request as written and does not translate between wire formats, so an OpenAI-format request reaches OpenAI or an OpenAI-compatible provider, but not Anthropic — that request is rejected with400 and x-to11-error-code: cross_dialect. Call Anthropic models with the Anthropic SDK. See Which SDK to call a provider with.
