I've never worked on a web platform like Reddit, nor with any per-request priced APIs. Reddit's charge of $0.00024 per request still looks like it is _significantly_ above what their own costs are.
Wasn't Reddit's pay-for-API-access announcement originally phrased as a desire to claw back some of the value that LLMs have found in Reddit data? I don't understand how per-request API pricing actually accomplishes that. (I was vaguely anticipating Reddit's API pricing to have some sort of expensive "firehose" endpoint for OpenAI/Google/Meta/etc to pull from.)
It looks like they're instead going to squeeze out all third-party apps instead. I don't think this bodes well for Reddit's future.
