Resolve Farcaster Users
Learn how to resolve Farcaster(s) fname/username/FID to 0x address, ENS, Lens, and XMTP and Reverse Resolution.
In this guide you will learn how to use Airstack to:
- Basic knowledge of GraphQL
JavaScript/TypeScript/Python
If you are using JavaScript/TypeScript or Python, Install the Airstack SDK:
npm
yarn
pnpm
pip
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:
React
Node
Python
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 } = 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.
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.

You can resolve an array of Farcaster user(s) to their 0x addresses:
https://app.airstack.xyz/query/rQQVTG8laa
Show 0x addresses of Farcaster user name dwr.eth and user ID 1
Query
Response
query GetAddressesOfFarcasters {
Socials(
input: {
filter: { identity: { _in: ["fc_fname:dwr.eth", "fc_fid:1"] } }
blockchain: ethereum
}
) {
Social {
userAssociatedAddresses
}
}
}
{
"data": {
"Socials": {
"Social": [
