I'm wondering about two things related to development of customer-facing programs that use paid APIs in the background:
Are you using your own API key and pay for the usage? How can you justify operation of programs that produce high costs but no income?
Isn't the API publicly exposed to the client-side and possible subject of theft and abuse?
This renders the extension pretty useless for older papers, doesn't it? There doesn't seem to be a fallback to prompt older papers in a whole because it exceeds the prompt limit.
