Ask HN: As a researcher, how can I access Similarweb's Ultimate Package API?

I reached out to SimialrWeb's sales consultant to get access to their API for my doctoral research. The company said that they do not sell access to their API/Ultimate package for research purposes. The Ultimate Package is only available to enterprises, but it's the only way one can use their API. I'd like to get any advice on how to access, or circumvent to gain access to, SimilarWeb's Ultimate package. Thank you in advance!
