This page presents basic queries that can be used to retrieve impacts of terminal and peripherals.

You use curl in command line to query Boavizta demo (public) API.

💡 You can format the results by using jq (curl -X 'GET' 'https://api.boavizta.org/v1/cloud/aws?instance_type=a1.xlarge' | jq)

Get the impacts of a laptop with a default usage

In this query, we compute the impact of a laptop

Query :

curl -X 'GET' \
  'https://api.boavizta.org/v1/terminal/laptop?verbose=false' \
  -H 'accept: application/json'

                "warnings": [
                    "Generic data used for impact calculation."
                ]
            },

            "embedded": "not implemented",
            "use": "not implemented"
        }
    }
}

This query returns :

  • The impacts for the default criteria (gwp, pe, adp) since no impact is specified
  • The total embedded impacts of the laptop since no duration is given
  • The usage impacts of the laptop during its life duration, since no duration is given
  • Error margins are provided in the form of min & max values for both embedded and usage impacts
  • Significant figures are provided for each value

Get the impact of a desktop with a custom usage

In this query, we compute the impact of a desktop with a custom usage. Since verbose=true the api will return the values used during the computation.

curl -X 'POST' \
  'http://localhost:5000/v1/terminal/desktop?verbose=true&duration=8760&criteria=gwp&criteria=adp' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "usage": {
    "avg_power":70,
    "use_time_ratio":0.3,
    "usage_location": "FRA"
  }
}'

This query returns :

  • The impacts for both gwp and adp criteria since criteria=gwp&criteria=adp
  • The API will use an average electrical consumption of 70 Watt/hours 30% of the time (since use_time_ratio=0.3) for one year (since duration is set at 8760 hours).
  • Usage impacts will be assessed for the French electrical mix impacts since usage_location='FRA'
  • Embedded impacts will be allocated on one year (since duration is set at 8760 hours).
