This integration method is maintained but no longer actively developed. For the best experience and latest features, use our new AI Gateway with unified API access to 100+ models.
You can follow their documentation here: https://docs.mistral.ai/

​
Gateway Integration

1

Create a Helicone account

Log into helicone or create an account. Once you have an account, you can generate an API key.
2

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.
3

Set HELICONE_API_KEY and MISTRAL_API_KEY as environment variable

HELICONE_API_KEY=<your API key>
MISTRAL_API_KEY=<your API key>
4

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/completionsand then add the following authentication headers:
Authorization: Bearer <your API key>
Now you can access all the models on Mistral AI with a simple fetch call:

​
Example

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

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();
