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

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:

React

npm install @airstack/airstack-react

Node

npm install @airstack/node

React

yarn add @airstack/airstack-react

Node

yarn add @airstack/node

React

pnpm install @airstack/airstack-react

Node

pnpm install @airstack/node

pip install airstack

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

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

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

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);

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.

Check A Given Farcaster User is A Follower of User(s) on Farcaster

You can use Airstack to check if user(s) is following a given Farcaster user on Farcaster.

This can be done by providing the given Farcaster name[^3] or ID on the Wallet top-level query's identity input and the user(s) in the socialFollowers:

Try Demo

Code

query isFollowing {
  Wallet(input: {identity: "fc_fname:ipeciura.eth", blockchain: ethereum}) {
    socialFollowers( # Check if fc_fname:ipeciura.eth is a follower of these user identities on Lens
      input: {filter: {identity: {_in: ["0xeaf55242a90bb3289dB8184772b0B98562053559", "betashop.eth", "yosephks.cb.id", "lens/@deepesh", "lens_id:100275", "fc_fname:dawufi", "fc_fid:602"]}, dappName: {_eq: farcaster}}}
    ) {
      Follower {
        dappName
        dappSlug
        followingProfileId
        followerProfileId
        followingAddress {
          addresses
          socials {
            dappName
            profileName
          }
          domains {
            name
