I’m lucky I only shop at Black Mesa

It could work if you aggregated incompatible providers in the same category (such as weather) into one big aggregate API. That way, people wouldn’t need to refactor if their favorite API provider ramps up pricing or dies. But how would I trust you to keep offering the same service at a good price point instead of an established meteorological institution? Also, I think weather aggregators already exist.

I think they mean an API-aggregating API that would be called “100% API” with loads of services supported but no idea how to pay for all that.
