Some third-party apps for the social platform Reddit might soon stop working after the company made changes to a public interface that developers use to make their apps work. The change would impact apps like Apollo, which rely on Reddit’s application programming interface, or API, to function. For years, Reddit allowed third-party developers to tap into their public API to build just about anything, and the developers behind Apollo took advantage of this to build a slick smartphone app that serves as an alternative to Reddit’s own mobile app. Apollo pushed to pay millions to connect users to Reddit In April, executives at Reddit announced changes to their API that were largely seen as attempts to reign in developers who wanted to train artificial intelligence robots off the social platform’s content. But a key developer behind Apollo said the changes would have another consequence: Third-party platforms will soon have to pay if they want to continue connecting their users to Reddit’s services.

Apollo has not disclosed user figures in mobile app usage, but Selig said users made a collective 7 billion call requests last month, which would have cost the company $1.7 million under Reddit’s new API pricing structure. Assuming the same number of calls were made each month, Apollo said its bill would come out to over $20 million per year. Reddit stands firm on new…Your favorite Reddit app might soon stop working
