⏭️Next.js (Browser)

Learn how to integrate Airstack APIs to your Next.js client-side (browser) application, using the Airstack Web SDK.

In this tutorial, you will learn how to start integrating Airstack API into your Next.js application.

Table Of Contents

Step 0: Pre-requisites

Step 1: Install Airstack Web SDK

Use a package manager to install the Airstack Web SDK into your Next.js project:

npm install @airstack/airstack-react

Step 2: Set Environment Variable

Create a new .env file:

touch .env

Add the Airstack API key as the environment variable:


Step 3: Initialize SDK

Wrap your component with the AirstackProvider from the SDK to initialize it with the Airstack API key:

import { init, AirstackProvider } from "@airstack/airstack-react";

export default function App({ Component, pageProps }) {
  return (
    <AirstackProvider apiKey={process.env.NEXT_PUBLIC_AIRSTACK_API_KEY ?? ""}>
      <Component {...pageProps} />

Step 4: Call Your Query

Once you have initialized the SDK, you can use the useQuery to call the Airstack API.

Below you have been provided with Airstack query to fetch the 0x address, Lens, and Farcaster owned by vitalik.eth:

For more query examples, check out Guides for various use cases you can build with Airstack.

import { useQuery } from "@airstack/airstack-react";

interface QueryResponse {
  data: Data | null;
  loading: boolean;
  error: Error | null;

interface Data {
  Wallet: Wallet;

interface Error {
  message: string;

interface Wallet {
  socials: Social[];
  addresses: string[];

interface Social {
  dappName: "lens" | "farcaster";
  profileName: string;

const query = `
query MyQuery {
  Wallet(input: {identity: "vitalik.eth", blockchain: ethereum}) {
    socials {

const Component = () => {
  const { data, loading, error }: QueryResponse = useQuery<Data>(query, {}, { cache: false });

  if (loading) {
    return <p>Loading...</p>;

  if (error) {
    return <p>Error: {error.message}</p>;

  // Render your component using the data returned by the query

export default Component;

The data variable will return and logged into your browser's console as follows:

  "data": {
    "Wallet": {
      "socials": [
          "dappName": "farcaster",
          "profileName": "vitalik.eth"
          "dappName": "lens",
          "profileName": "lens/@vitalik"
      "addresses": ["0xd8da6bf26964af9d7eed9e03e53415d37aa96045"]
