Organised as “get a key → configure your tool → make your first request”, covering the major agent tools and SDKs.
This gateway provides access to Claude, GPT, Gemini, and other models through one URL and API key, with native Anthropic, OpenAI, and Gemini protocol compatibility. Connect compatible tools and SDKs by changing the Base URL and key.
Suggested reading order
