Use Cases

​
Verify Group Details

Check group information before adding factors: 
group = requests.get(
    f"https://api.dcycle.io/api/v1/custom_emission_groups/{group_id}",
    headers=headers
).json()

if group['category'] == 'purchases':
    print(f"✅ Correct category for adding purchase factors")
else:
    print(f"❌ Wrong category: {group['category']}")

ghg_type_name = {1: 'Fossil', 2: 'Biogenic', 3: 'Mixed'}[group['ghg_type']]
print(f"GHG Type: {ghg_type_name}")

​
Display Group Information

Show group details in a UI: 
async function displayGroupInfo(groupId) {
  const group = await axios.get(
    `https://api.dcycle.io/api/v1/custom_emission_groups/${groupId}`,
    { headers }
  ).then(res => res.data);

  document.getElementById('group-name').textContent = group.name;
  document.getElementById('group-desc').textContent = group.description;
  document.getElementById('group-category').textContent = group.category.toUpperCase();

  const ghgTypes = {1: 'Fossil', 2: 'Biogenic', 3: 'Mixed'};
  document.getElementById('group-ghg').textContent = ghgTypes[group.ghg_type];
}

​
Audit Group Metadata

Check group validity and ownership: 
group = requests.get(
    f"https://api.dcycle.io/api/v1/custom_emission_groups/{group_id}",
    headers=headers
).json()

from datetime import date

print(f"Group: {group['name']}")
print(f"Created by: {group.get('group_uploaded_by', 'Unknown')}")

if group['group_start_date'] and group['group_end_date']:
    start = date.fromisoformat(group['group_start_date'])
    end = date.fromisoformat(group['group_end_date'])
    today = date.today()

    if start <= today <= end:
        print(f"✅ Group is currently valid")
    elif today < start:
        print(f"âŗ Group not yet valid (starts {start})")
    else:
        print(f"❌ Group expired (ended {end})")
else:
    print(f"ℹī¸ No validity period set")
