Warning

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#

Create a Helicone account

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

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.

Set HELICONE_API_KEY and MISTRAL_API_KEY as environment variable

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

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:

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();
