Infistar offers a shared account and API key across multiple AI models. Keep the request format your application already uses and select a model that supports that endpoint.

​
Base URL

For OpenAI-compatible clients, use: 
https://infistar.ai/v1
For networks in mainland China, use https://infistar.cc/v1. Both addresses use the same account and API key. Configure one base URL per client; do not append /v1 twice. Claude Code uses the site origin without /v1, as explained in its setup guide.

​
Authentication

Create a key in Console → Token Management and send it in the request header: 
Authorization: Bearer YOUR_API_KEY
Keep the key on your server. See Authentication and permissions.

​
Discover available models

Call GET /v1/models with the key you will use. Copy the exact returned model ID; a display name, plan name, or supplier name is not a model ID. A listed model does not necessarily support every endpoint. Check its current interface types in Model Square.

Gemini, embeddings, reranking, realtime audio, speech, and transcription depend on the selected model and endpoint. The broader compatibility matrix (Chinese) provide the remaining interfaces. Start with a small non-streaming request. Then test only the streaming, tools, media, or other capabilities your application actually requires. Check the response and usage log before increasing traffic.
