Twitter has shared more details about the upcoming changes to its API that will require most developers to pay in order to keep using its developer tools. In an update, the company said that there will be “a new form of free access” that will allow “Tweet creation of up to 1,500 Tweets per month.”

That clarification means that many of Twitter’s so-called “good” bots — the automated accounts that tweet everything from historical photos to helpful reminders — will be able to continue on the platform. Previously, the future of these accounts was uncertain as many bot makers said they would not pay for API access.
