# SDKs & Libraries (/docs/sdks)


Compatible SDKs [#compatible-sdks]

Yunxin is fully compatible with the **OpenAI SDK** — simply change the base URL and API key. No custom SDK needed.

Python (OpenAI SDK) [#python-openai-sdk]

```bash
pip install openai
```

```python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.yuhuanstudio.com/v1"
)

response = client.chat.completions.create(
    model="model-id",
    messages=[{"role": "user", "content": "Hello!"}]
)
```

JavaScript / TypeScript (OpenAI SDK) [#javascript--typescript-openai-sdk]

```bash
npm install openai
```

```typescript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://api.yuhuanstudio.com/v1",
});

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

cURL [#curl]

No installation needed — use cURL directly:

```bash
curl https://api.yuhuanstudio.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"model": "model-id", "messages": [{"role": "user", "content": "Hello!"}]}'
```

Anthropic SDK (for Messages format) [#anthropic-sdk-for-messages-format]

If you prefer Anthropic's native message format:

```python
from anthropic import Anthropic

client = Anthropic(
    api_key="YOUR_API_KEY",
    base_url="https://api.yuhuanstudio.com/v1"
)

message = client.messages.create(
    model="model-id",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)
```

Environment Variables [#environment-variables]

We recommend using environment variables for all SDKs:

```bash
export YUNXIN_API_KEY="yx-your-key-here"
export YUNXIN_BASE_URL="https://api.yuhuanstudio.com/v1"
```

```python
import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["YUNXIN_API_KEY"],
    base_url=os.environ["YUNXIN_BASE_URL"]
)
```
