## Step 1. Paste the HTTP Request node

Copy the JSON and paste it on the canvas. The node reads the cnpj field of the incoming item.

```json
{
  "nodes": [
    {
      "parameters": {
        "url": "=https://radar-cnpj.com/api/cnpj/{{ $json.cnpj }}",
        "options": {
          "timeout": 20000
        }
      },
      "name": "Radar CNPJ",
      "type": "n8n-nodes-base.httpRequest",
      "typeVersion": 4.2,
      "position": [
        900,
        300
      ]
    }
  ],
  "connections": {}
}
```

## Step 2. Connect and run
