Get LCA Dashboard

Retrieve the calculated environmental impact results for a specific LCA, organized by EN 15804 life cycle stages (A1–A4, B6, B7). Each stage contains impact values across all selected impact categories.

Request

Path Parameters

lca_id · uuid · required

The UUID of the LCA portfolio

Example: a1b2c3d4-e5f6-7890-abcd-ef1234567890

Headers

x-api-key · string · required

Your API key for authentication

x-organization-id · string · required

Your organization UUID

Query Parameters

view · string · default: "system"

Allocation view for co-product LCAs.

Available values:

• system — Total system impact (default)
• product_total — Impact allocated to a specific co-product (requires output_product_id)
• product_unit — Per-unit impact of a co-product (requires output_product_id)

output_product_id · uuid

UUID of the output product for co-product allocation views (product_total or product_unit). Required when view is not system.

Example: bf800281-bcc7-42f4-81e4-8ec9abb9745e

Co-Product Allocation Example

For LCAs with multiple output products, use the view and output_product_id parameters to see allocated impacts:

# Per-unit impact for a specific co-product
curl -X GET "https://api.dcycle.io/lca/portfolio/{lca_id}/dashboard?view=product_unit&output_product_id={product_id}" \
  -H "x-api-key: ${DCYCLE_API_KEY}" \
  -H "x-organization-id: ${DCYCLE_ORG_ID}"

Common Errors

404 Not Found

Cause: LCA does not exist or does not belong to the specified organization

{
  "code": "NOT_FOUND",
  "detail": "LCA not found"
}

422 Validation Error

Cause: product_total or product_unit view requested without output_product_id

{
  "detail": "output_product_id is required for product_total and product_unit views"
}
