💰Get Token Balances

Learn how to get ERC20, 721, 1155, and POAPs Of Lens Profile(s), including images and metadata, on Ethereum, Polygon, and Gnosis (POAPs).

Airstack provides easy-to-use APIs for enriching Lens applications and integrating on-chain and off-chain data with Lens.

In this tutorial, you will learn how to fetch Lens user(s) asset holdings which comprise ERC20s, ERC721s, ERC115s, and POAPs on Ethereum, Polygon, and Gnosis.

In this guide you will learn how to use Airstack to:

• Get All ERC20s Owned By Lens Profile(s)

• Get All NFTs Owned By Lens Profile(s)

• Get All POAPs Owned By Lens Profile(s)

Pre-requisites

• An Airstack account (free)

• 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 asyncio

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

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

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

Node

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

init("YOUR_AIRSTACK_API_KEY");

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

const { data, error } = 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())

Other Programming Languages

To access the Airstack APIs in other languages, you can use https://api.airstack.xyz/gql as your GraphQL endpoint.

🤖 AI Natural Language​

Airstack provides an AI solution for you to build GraphQL queries to fulfill your use case easily. You can find the AI prompt of each query in the demo's caption or title for yourself to try.
