OpenAI-Compatible API

The platform standardizes on the OpenAI Chat Completions / Responses format and translates requests to whatever each upstream provider expects (Anthropic, Gemini, DeepSeek, xAI, Moonshot, and more).

  • One codebase, one SDK — call every model the same way
  • Switch models by changing the model parameter
  • No per-vendor SDKs or auth to maintain

Supported endpoint formats:

Format Description
openai OpenAI Chat Completions (/v1/chat/completions)
openai-response OpenAI Responses API (/v1/responses)
anthropic Anthropic Messages compatible
gemini Gemini compatible
image-generation Image generation (/v1/images/generations)
