Vehicle Attributes

​

Core Vehicle Information

• name (string, optional): Custom name or alias for the vehicle (e.g., “Company Fleet Car #1”)
• type (string, required): Type of vehicle usage - passenger or freight
• ownership (string, required): Ownership type - owned or rented
• license_plate (string, required): Vehicle registration/license plate number
• country (string, required): ISO 3166-1 country code (2-3 characters)

​

Vehicle Classification

• unknown_vehicle_id (UUID, required): UUID of the unknown vehicle type for categorization
• vehicle_fuel_id (UUID, optional): UUID of the vehicle fuel type (petrol, diesel, electric, hybrid, etc.)
• registration_year (integer, optional): Year of vehicle registration (YYYY format)
• market_segment (string, optional): Vehicle market segment classification
• size (string, optional): Vehicle size category (small, medium, large)

​

Emission Data

• custom_emission_factor_id (UUID, optional): UUID of a custom emission factor for organizations with custom emission data
• co2e (float, read-only): Calculated CO2 equivalent emissions in kg CO2e

​

Workflow

​

Creating a Fleet Vehicle

1. Retrieve available options (if needed):
   • Get unknown vehicle types from /unknown-vehicles endpoint
   • Get fuel types from /vehicle-fuels endpoint
   • Get market segments from /vehicles/market-segments endpoint
2. Create the vehicle with:
   • Required fields: type, ownership, license_plate, country, unknown_vehicle_id
   • Either vehicle_fuel_id or custom_emission_factor_id for emissions calculation
3. Track emissions through the co2e field in responses

​

Filtering and Pagination

• Filter by status (active, archived, error)
• Filter by ownership type (owned, rented)
• Filter by fuel type or unknown vehicle type
• Search by vehicle name or license plate
• Sort results (by name, license plate, creation date)
• Include child organizations in results

Track Corporate Fleet Emissions

# Get all active vehicles
vehicles = requests.get(
    "https://api.dcycle.io/v1/vehicles",
    headers={
        "x-api-key": api_key,
        "x-organization-id": org_id
    },
    params={"status": ["active"]}
)

total_co2e = sum(v["co2e"] for v in vehicles.json()["items"])
print(f"Fleet total: {total_co2e} kg CO2e")

Compare Vehicle Options

# Create vehicles with different fuel types
vehicles_to_test = [
    {"name": "Diesel Van", "vehicle_fuel_id": diesel_uuid},
    {"name": "Electric Van", "vehicle_fuel_id": electric_uuid},
    {"name": "Hybrid Van", "vehicle_fuel_id": hybrid_uuid}
]

for vehicle in vehicles_to_test:
    response = requests.post(
        "https://api.dcycle.io/v1/vehicles",
        headers=headers,
        json=vehicle
    )
    data = response.json()
    print(f"{data['name']}: {data['co2e']} kg CO2e")
