OpenAI Compatible Format

If you're using the OpenAI SDK, just change base_url and api_key:

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="http://47.253.249.242/v1",
    api_key="sk-yq-your-key-here"
)

# Non-streaming
response = client.chat.completions.create(
    model="claude-sonnet-4-20250514",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Hello!"}
    ],
    max_tokens=1024
)
print(response.choices[0].message.content)

# Streaming
stream = client.chat.completions.create(
    model="claude-sonnet-4-20250514",
    messages=[{"role": "user", "content": "Write a poem"}],
    stream=True
)
for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

curl

    "messages": [{"role": "user", "content": "Hello"}],
    "max_tokens": 1024
  }'

Node.js

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "http://47.253.249.242/v1",
  apiKey: "sk-yq-your-key-here",
});

const response = await client.chat.completions.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
});

console.log(response.choices[0].message.content);

Anthropic Compatible Format

Also supports Anthropic Messages API format:

Python (Anthropic SDK)

import anthropic

client = anthropic.Anthropic(
    base_url="http://47.253.249.242",
    api_key="sk-yq-your-key-here"
)

message = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)
print(message.content[0].text)

curl (Anthropic)

curl http://47.253.249.242/v1/messages \
  -H "x-api-key: sk-yq-your-key-here" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-4-20250514",
    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Hello"}]
  }'
