Tutorial
Testing methods and usage tips
First steps: sign up, add ¥10, and create an API key
Get an API key and the endpoint address in three steps, then paste them into Cherry Studio, Chatbox, Codex or any other client.
Claude Code with Xisu AI (Windows / macOS / Linux)
Install Claude Code, set three environment variables for the address, key and model, and code in your terminal with Claude models on Xisu AI.
Codex CLI with Xisu AI: set up the Responses API in one go
Install Codex CLI, add one config.toml and one environment variable to run on Xisu AI, plus how Responses differs from Chat Completions.
Connect to the Xisu AI API in 5 minutes: Python, Node.js and curl
Sign up, add funds, create a key, set base_url, send your first request in Python, Node.js or curl, then check tokens and cost in Request log.
Use your existing SDK or client
Connect official OpenAI SDKs, desktop clients such as Cherry Studio, or terminal coding tools to Xisu AI by changing only the base_url and API key. Covers whether to include /v1, empty model lists, and clients still calling the official API.
How to check you are getting the real model
Asking who it is proves nothing. Check the tokenizer fingerprint, vendor-only features and each call by request_id, with a ready-to-run script.
