Want to try it out? Fill out the form bellow to get an API key.

The API is still in an experimental phase, more features will be added soon
Thank you, you will receive an API key by email in no more than 72 hours.

API Documentation

General usage and limitations

Nowtricity API gives you access to live and historical electricity production emissions data in grams CO2eq/kWh from multiple countries. Check the frequently asked questions for more information on how that data is calculated.

The API requests are made with a simple GET to a URL and data is returned in JSON.

It's free to use, but please play nice. Cache data on your end and limit the number of requests made. Request throttling is implemented to avoid overloading the server.

Cite the data source as Nowtricity. A link back would be awesome, if possible.

Authentication

All requests to the API need to have your API key sent in a header X-Api-Key

You can easily set this in Postman (Authorization > Type: API Key > Key: X-Api-Key > Value: Your key) or with cURL curl 'https://www.nowtricity.com/api/countries/' -H 'X-Api-Key: Your key'

            "unit": "g CO2eq/kWh",
            "timestamp": 1656676800,
            "dateUTC": "2022-07-01T12:00:00+00:00",
