At the time of writing Engie communicates its hourly dynamic rate through PDF and a publicly documented API was not identified. PDF is hard to integrate with in an automatic way, this tool is a very naive implementation into exposing the pricing information extracted from the PDF into a CSV allowing it to be used by whatever automation tool you desire to use.
Usage:
docker run --rm -ti -v $(pwd):/files jandeschuttere/engie-dynamic-rate-pdftocsv:latest /files/daily_prices_eSpot.pdf It is expected that the above command is run in the directory where the file "daily_prices_eSpot.pdf" is located which is the name of the PDF retrieved from Engie.
