Anthropic-compatible API

Reference for using the Qiuqiu Token Anthropic-compatible API, including use cases, authentication, paths, and request format.

Use the Anthropic-compatible API for Claude Code, Claude Desktop, Cherry Studio’s Anthropic provider, or applications that call the Messages endpoint directly.

When a client asks for a Claude, Anthropic, or Gateway Base URL, use the root URL without appending /v1. When you send HTTP requests yourself, call the Messages path under that root URL.

Base URL and path

Base URL: https://api.qiuqiutoken.net
Request path: /v1/messages
Full request URL: https://api.qiuqiutoken.net/v1/messages

POST/v1/messages

Authentication

Use an API token created in the console. For Claude, Anthropic clients, or Claude models, choose the matching token group; do not leave the token in the default group.

For direct HTTP requests, include these headers:

content-type: application/json
x-api-key: sk-your-token
anthropic-version: 2023-06-01

Claude Desktop’s third-party inference settings do not ask you to write raw headers. In that client, set Gateway auth scheme to bearer.

Minimal request

Replace <model-id> with an available Claude model name from the Model Catalog, and replace sk-your-token with an API token from the matching group.

curl https://api.qiuqiutoken.net/v1/messages \
-H "content-type: application/json" \
-H "x-api-key: sk-your-token" \
-H "anthropic-version: 2023-06-01" \
-d '{
  "model": "<model-id>",
  "max_tokens": 1024,
  "messages": [
    { "role": "user", "content": "Hello" }
  ]
}'

Notes

When switching routes, replace only the Base URL. Keep the API token, model name, and token group unchanged.
The model name must match an available name in the Model Catalog. For model 404s, check the model name and token group first.
