"{"errors":[{"message":"Your current API plan does not include access to this endpoint, please see https://developer.twitter.com/en/docs/twitter-api https://developer.twitter.com/en/docs/twitter-api for more information","code":467}]}" I received this message, same as everyone else. I just have a plain old, non-checked account. I occasionally use an unfollower service that uses this API thing (What even is API?), but I don't see how that's grounds for denying me or anyone else in the same boat access to Twitter. Am I missing something here?
