In this guide you will learn how to use Airstack to get ERC20 tokens owned by user(s).

Pre-requisites

• An Airstack account

• Basic knowledge of GraphQL

Get Started

JavaScript/TypeScript/Python

If you are using JavaScript/TypeScript or Python, Install the Airstack SDK:

npm

React

npm install @airstack/airstack-react

Node

npm install @airstack/node

yarn

React

yarn add @airstack/airstack-react

Node

yarn add @airstack/node

pnpm

React

pnpm install @airstack/airstack-react

Node

pnpm install @airstack/node

pip

pip install airstack

Then, add the following snippets to your code:

React

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

init("YOUR_AIRSTACK_API_KEY");

const query = `YOUR_QUERY`; // Replace with GraphQL Query

const Component = () => {
  const { data, loading, error } = useQuery(query);

  if (data) {
    return <p>Data: {JSON.stringify(data)}</p>;
  }

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

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

Node

import { init, fetchQuery } from "@airstack/node";

init("YOUR_AIRSTACK_API_KEY");

const query = `YOUR_QUERY`; // Replace with GraphQL Query

const { data, error } = await fetchQuery(query);

console.log("data:", data);
console.log("error:", error);

Python

import asyncio
from airstack.execute_query import AirstackClient

api_client = AirstackClient(api_key="YOUR_AIRSTACK_API_KEY")

query = """YOUR_QUERY""" # Replace with GraphQL Query

async def main():
    execute_query_client = api_client.create_execute_query_object(
        query=query)

    query_response = await execute_query_client.execute_query()
    print(query_response.data)

asyncio.run(main())
