# SDKs

> Use the official OpenAI and Anthropic SDKs. Change the base URL and the key.


NotHoly does not ship its own SDK. The official OpenAI and Anthropic SDKs work after you change two settings.

| SDK | Base URL | Key |
|---|---|---|
| OpenAI (Python, JavaScript, Go, others) | `https://api.notholy.com/v1` | `NOTHOLY_API_KEY` as the API key |
| Anthropic (Python, JavaScript) | `https://api.notholy.com` | `NOTHOLY_API_KEY` as the API key |

## OpenAI SDK

```python test
import os
from openai import OpenAI

client = OpenAI(base_url="https://api.notholy.com/v1", api_key=os.environ["NOTHOLY_API_KEY"])

r = client.chat.completions.create(model="notholy-specter", messages=[{"role": "user", "content": "What is CWE-79?"}])
print(r.choices[0].message.content)
```

## Anthropic SDK

```python test
import os
from anthropic import Anthropic

client = Anthropic(base_url="https://api.notholy.com", api_key=os.environ["NOTHOLY_API_KEY"])
m = client.messages.create(
    model="notholy-specter",
    max_tokens=512,
    messages=[{"role": "user", "content": "What is CWE-89?"}],
)
print(m.content[0].text)
```

```js test
import Anthropic from '@anthropic-ai/sdk';

const client = new Anthropic({ baseURL: 'https://api.notholy.com', apiKey: process.env.NOTHOLY_API_KEY });
const m = await client.messages.create({
  model: 'notholy-specter',
  max_tokens: 512,
  messages: [{ role: 'user', content: 'What is CWE-89?' }],
});
console.log(m.content[0].type === 'text' ? m.content[0].text : '');
```
