It might make sense to also add a section to the article considering why you'd want to verify an API signature instead of calling the API again. Some examples I could think of: - You don't have access to (that part of) the API, but to its public key - The data in question has been deleted - The entire API or even Service is gone - The API call involves some complex calculations that takes a long time - The data might have to be verified without access to the API or the network as a whole - You are being Surveilled and/or your access to the API or some of its endpoints is being restricted
