SerpAPI (which seems like a good product from my singular use), has a really confusing pricing page:

What is a Legal US Shield? And why do I have to pay for it? Does the free plan not include it either?

From their docs:

We are committed to maintaining legal and ethical web scraping practices and providing our customers with peace of mind. This is one reason that for all plans from the production plan and upwards we offer our Legal US Shield. Although web scraping is legal in the US, we provide this coverage in case there were ever any issues to arise. Our Legal US Shield would cover any legal questions regarding only the scraping and parsing of data, not the use of said data. We continue to offer this protection to ease any concerns our customers may have in regards to web scraping.

But really, why does this not apply to the free plans? Seems weird.
