## Buscar por ID

### Un solo usuario

<CodeGroup dropdown>
  ```bash cURL theme={null}
  curl "https://api.x.com/2/users/2244994945?\
  user.fields=created_at,description,verified,public_metrics" \
    -H "Authorization: Bearer $BEARER_TOKEN"
  ```

  ```python title="Python SDK" lines wrap icon="python" theme={null}
  from xdk import Client

  client = Client(bearer_token="YOUR_BEARER_TOKEN")

  # Obtener usuario por ID
  response = client.users.get(
      "2244994945",
      user_fields=["created_at", "description", "verified", "public_metrics"]
  )

  print(f"Name: {response.data.name}")
  print(f"Username: {response.data.username}")
  print(f"Followers: {response.data.public_metrics.followers_count}")
  ```

  ```javascript title="JavaScript SDK" lines wrap icon="square-js" theme={null}
  import { Client } from "@xdevplatform/xdk";

  const client = new Client({ bearerToken: "YOUR_BEARER_TOKEN" });

  // Obtener usuario por ID
  const response = await client.users.get("2244994945", {
    userFields: ["created_at", "description", "verified", "public_metrics"],
  });

  console.log(`Name: ${response.data?.name}`);
  console.log(`Username: ${response.data?.username}`);
  console.log(`Followers: ${response.data?.public_metrics?.followers_count}`);
  ```
</CodeGroup>
