    AESO Application Programming Interface (API) – new data

    On January 22, 2021, the AESO announced the release of the AESO’s first Application Programming Interface (API). APIs allow AESO data to be accessed programmatically, providing for more reliability, and eliminating the need to ‘screen scrape’ our reports and webpages.

    Effective March 18, 2021, historical pool price data will be available via secure API.

    Additional APIs containing other public data currently available in ETS, ADaMS, and other sources will continue to be added in the future. 

    To access AESO’s API page:

    • You will be sent an email with your API key. Click on the “Authorize” button on the AESO APIs homepage to authorize your access.
