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:

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:

React

npm install @airstack/airstack-react

Node

npm install @airstack/node

Then, add the following snippets to your code:

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
};

Other Programming Languages

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