Twitter is adding a fee to another previously free service next week: its application programming interface (API). This allows people « to find and retrieve, engage with, or create » tweets, users, spaces, direct messages and more, according to Twitter.
« Starting February 9, we will no longer support free access to the Twitter API, both v2 and v1.1. A paid basic tier will be available instead, » the Twitter Dev account tweeted earlier today. Twitter did not say how much access would cost.
Twitter API is used by developers who create third party tools on the platform and researchers who analyze the data in their work.
