🧍Check Single User

Learn how to use Airstack to check if a single user has XMTP or not.

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

In this guide you will learn how to use Airstack to check if a single user has XMTP enabled:

Pre-requisites

An Airstack account
Basic knowledge of GraphQL
Basic knowledge of XMTP

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.

By 0x Address

Simply use the following query to check if a user has XMTP or not with this example of a user that has an XMTP:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: {
      blockchain: ALL
      filter: { owner: { _eq: "0xa91c2d10a993d14f842d23b97f2ab3fdf6b5b9aa" } }
    }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

Here's an example of user the does not have any XMTP:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: {
      blockchain: ALL
      filter: { owner: { _eq: "0x5416e5dc14caa0950b2a24ede1eb0e97c360bcf5" } }
    }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": null
    }
  }
}

By Solana Address

Simply use the following query to check if a solana address has enabled XMTP or not with this example of a user that has an XMTP:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: {
      blockchain: ALL
      filter: { owner: { _eq: "GJQUFnCu7ZJHxtxeaeskjnqyx8QFAN1PsiGuShDMPsqV" } }
    }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

By ENS

With Airstack Identity API, you can simply swap the address input to any ENS names, either on-chain or off-chain (e.g. ):

Try Demo

Code

query MyQuery {
  XMTPs(input: { blockchain: ALL, filter: { owner: { _eq: "vitalik.eth" } } }) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

By cb.id

With Airstack Identity API, you can simply swap the address input to any cb.id:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: { blockchain: ALL, filter: { owner: { _eq: "yosephks.cb.id" } } }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

By Lens Profile Name or ID

With Airstack Identity API, you can simply swap the address input owner to any Lens profile name:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: { blockchain: ALL, filter: { owner: { _eq: "lens/@vitalik" } } }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

Alternatively, you can also swap the address input owner to any Lens profile ID, either in or hex form:

Try Demo

Code

query MyQuery {
  XMTPs(
    input: { blockchain: ALL, filter: { owner: { _eq: "lens_id:100275" } } }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

By Farcaster Name or ID

With Airstack Identity API, you can simply swap the address input owner to any :

Try Demo

Code

query MyQuery {
  XMTPs(
    input: {
      blockchain: ALL
      filter: { owner: { _eq: "fc_fname:vitalik.eth" } }
    }
  ) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}

Alternatively, you can also swap the address input owner to any Farcaster ID:

Try Demo

Code

query MyQuery {
  XMTPs(input: { blockchain: ALL, filter: { owner: { _eq: "fc_fid:5650" } } }) {
    XMTP {
      isXMTPEnabled
    }
  }
}

{
  "data": {
    "XMTPs": {
      "XMTP": [
        {
          "isXMTPEnabled": true
        }
      ]
    }
  }
}
