BrainLink Developer Quickstart

BrainLink Developer Docs

Integrating BrainLink in your app allows your users to connect their brains with a single click. This allows you to get rid of the inference costs and provides your app with a simple way to monetize without paywalls or sign-up forms.

By integrating BrainLink your app is automatically listed in the BraiLink AI store, which is a powerful distribution channel and source of users.

We are devs building for fellow devs.

Integrating BrainLink

And that’s all! Now your users will pay for the inference they consume by connecting their BrainLink account with your application in one click, so you don’t have to request them API keys.

​

Running inference

BrainLink’s API is fully OpenAI compatible, so you can directly use the OpenAI SDK or any other compatible one, just change the baseURL to https://www.brainlink.dev/api/v1.

For example:

if (BrainLink.isConnected()) {
    const userAccessToken = await BrainLink.getUserToken();
    const openai = new OpenAI({
        baseURL: "https://www.brainlink.dev/api/v1",
        apiKey: userAccessToken,
        // Required to use the OpenAI SDK in the browser.
        // Since your app is securely using the user's access token via BrainLink, it's totally safe to use the SDK on the browser.
        dangerouslyAllowBrowser: true,
    });
}

const completion = await openai?.chat.completions.create({
    model: "google/gemini-2.0-flash-lite-preview-02-05:free",
    messages: messages,
});
