Hi Ieadgen,
Thanks for reaching out. With regards to your concern about getting SearchImpressionShare and ShareAbsoluteTopImpressionShare at the keyword level, you can use Keyword performance report using the SearchImpressionShare and SearchAbsoluteTopImpressionShare field. The Auction Insights report is not available via API. Our team is already aware of this feature request. Please keep an eye on our blog post for future updates. Let us know if you have any additional concerns.
Let me know if you have any questions.
Thanks,

Hi Ieadgen,
Thanks for reaching out. With regards to your concern about the competitor domain, Unfortunately you will not be able to get data of your competitors domain through the API. However, you can get your impression share by running a report such as the Keywords Performance Report and include the field SearchImpressionShare.
Thanks,
