I'll carry the odd opinion here and say there's actually a way this could be useful. You have to add value to a product to make it worth your time and effort, increase adoption, and make it at least self-sustainable. Find reasons to justify why this should exist. For a start - This could save time on projects where similar data has to be loaded on a page from multiple api endpoints but it doesn't match. - an old example, but one that I fought once - looking up the time zone of a city from one api, then the time offset from UTC from another api, and trying to relate it all together. That meant my functions had to match that data up on the client side because there were imperfect text matches.

As a second example, if you were able to cache or keep record of data from upstream endpoints that often takes a while to gather because they can't/won't, you might offer a performance advantage or datasets which were previously unavailable to a user without monitoring data coming from that API over an extended period of time.

There's more you can do, but that hinges again on what I previously said, find your pitch and solve problems that the others have created and won't fix.
