The parameter "amount" should instead be called something like "count"

[metov]

The endpoint /facts accepts a parameter amount which specifies the number of facts requested. However, "amount" technically refers to uncountable nouns, and hence implies that the value is a float: https://english.stackexchange.com/questions/9439/amount-vs-number-vs-quantity

Since the type is integer and in any case you cannot have half a fact, it would be more natural to call this something like count.

You have a good point. I will look into changing this without breaking existing functionality
