# Mistral AI Integration

> Connect Helicone with Mistral AI, a platform that provides state-of-the-art language models including Mistral-Large and Mistral-Medium for various AI applications.

<Warning>
  This integration method is maintained but no longer actively developed. For the best experience and latest features, use our new [AI Gateway](/gateway/overview) with unified API access to 100+ models.
</Warning>

You can follow their documentation here: [https://docs.mistral.ai/](https://docs.mistral.ai/)

# Gateway Integration

<Steps>
  <Step title="Create a Helicone account">
    Log into [helicone](https://www.helicone.ai) or create an account. Once you have an account, you
    can generate an [API key](https://helicone.ai/developer).
  </Step>

  <Step title="Create a Mistral AI account">
    Log into console.mistral.ai or create an account. Once you have an account, you
    can generate an API key from your dashboard.
  </Step>

  <Step title="Set HELICONE_API_KEY and MISTRAL_API_KEY as environment variable">
    ```javascript theme={null}
    HELICONE_API_KEY=<your API key>
    MISTRAL_API_KEY=<your API key>
    ```
  </Step>

  <Step title="Modify the base URL and add Auth headers">
    Replace the following Mistral AI URL with the Helicone Gateway URL:

    `https://api.mistral.ai/v1/chat/completions` -> `https://mistral.helicone.ai/v1/chat/completions`

    and then add the following authentication headers:

    ```javascript theme={null}
    Authorization: Bearer <your API key>
    ```
  </Step>
</Steps>

Now you can access all the models on Mistral AI with a simple fetch call:

## Example

```bash theme={null}
curl \
  --header "Authorization: Bearer $MISTRAL_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "model": "mistral-large-latest",
    "messages": [{"role": "user", "content": "Say this is a test"}]
}' \
  --url https://mistral.helicone.ai/chat/completions
```

### TypeScript Example

```typescript theme={null}
const httpClient = new HTTPClient();
httpClient.addHook("beforeRequest", async (req) => {
  req.headers.set("Helicone-Auth", `Bearer ${process.env.HELICONE_API_KEY}`);
});

const mistral = new Mistral({
  apiKey: process.env.MISTRAL_API_KEY,
  serverURL: "https://mistral.helicone.ai",
  httpClient,
});

async function run() {
  const result = await mistral.chat.complete({
    model: "mistral-small-latest",
    stream: false,
    messages: [
      {
        content:
          "Who is the best French painter? Answer in one short sentence.",
        role: "user",
      },
    ],
  });

  // Handle the result
  console.log(result);
}

run();
```
