🚚 CO2 Emissions of Freight Shipments with Carbon Interface API and GPT-4o

### 3. Record Shipment Request Information and fetch emissions using the Carbon Interface API  
This starts by recording all the structured shipment information parsed by the AI Agent node. Then, we use the **Carbon Interface API** to estimate **CO₂ emissions** based on cargo weight, distance, and transportation method.

#### How to setup?

- **Setup Carbon Interface API Credentials**  
  1. Get your free API key: [Carbon Interface API Documentation](https://docs.carboninterface.com/#/)  
  2. Fill the API key in the HTTP Request node headers (`Bearer YOUR_API_KEY`)

- **Load records into the Google Sheet Node**  
  1. Add your Google Sheets API credentials to access your sheet  
  2. Select the file using the list, a URL, or its ID  
  3. Select the sheet where you want to log your shipping emissions  
  4. Map the fields:  
     **shipment_number**, **pickup_location**, **pickup_address**, **expected_pickup_time**, **temperature_control**, **destination_store_name**, **destination_address**, **expected_delivery_time**, **driving_distance_km**, **estimated_transit_min**, **cargo_quantity**, **cargo_weight_tons**, **weight_value_g**, **co2_kg**, **co2_estimation_time**

> Distance and weight values will be used to calculate carbon emissions via the Carbon Interface API.
