# Bruk CometAPI med OpenAI SDK-er

> Konfigurer OpenAI Python- og Node.js-SDK-ene for CometAPI ved å angi CometAPI API-nøkkelen og base-URL-en.

Bruk OpenAI SDK med CometAPI ved å endre to klientinnstillinger: API-nøkkelen og base-URL-en. Behold din eksisterende OpenAI-kompatible forespørselskode, og erstatt deretter model ID med en tilgjengelig CometAPI model ID.

## Installer SDK-en

Følgende kommando installerer OpenAI Python SDK:

```bash theme={null}
pip install openai
```

Følgende kommando installerer OpenAI Node.js SDK:

```bash theme={null}
npm install openai
```

## Python-klient

Følgende Python-eksempel oppretter en CometAPI-klient og sender en chat-forespørsel:

```python theme={null}
import os
from openai import OpenAI

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

completion = client.chat.completions.create(
    model="your-model-id",
    messages=[
        {
            "role": "user",
            "content": "Answer in one short sentence: What is CometAPI?",
        }
    ],
)

print(completion.choices[0].message.content)
```

Responsobjektet inneholder assistentmeldingen:

```json theme={null}
{
  "choices": [
    {
      "message": {
        "role": "assistant",
        "content": "CometAPI provides API access to models from multiple providers."
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 16,
    "completion_tokens": 12,
    "total_tokens": 28
  }
}
```

## Node.js-klient

Følgende Node.js-eksempel bruker `baseURL` med OpenAI SDK:

```javascript theme={null}
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.COMETAPI_KEY,
  baseURL: "https://api.cometapi.com/v1",
});

const completion = await client.chat.completions.create({
  model: "your-model-id",
  messages: [
    {
      role: "user",
      content: "Answer in one short sentence: What is CometAPI?",
    },
  ],
});

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

Responsformatet er det samme OpenAI-kompatible chat completion-formatet:

```json theme={null}
{
  "id": "chatcmpl_example",
  "object": "chat.completion",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "CometAPI provides API access to models from multiple providers."
      }
    }
  ]
}
```

## Vanlige feil

| Feil                       | Løsning                                                                              |
| -------------------------- | ------------------------------------------------------------------------------------ |
| `401`                      | Bekreft at `COMETAPI_KEY` er satt og at forespørselen bruker `Bearer`-autentisering. |
| SDK kaller fortsatt OpenAI | Angi `base_url` i Python eller `baseURL` i Node.js.                                  |
| Ugyldig model ID           | Velg en model ID fra [Models page](/no/overview/models).                             |
| Manglende `/v1`            | Bruk `https://api.cometapi.com/v1` for OpenAI-kompatible SDK-er.                     |
