Twitter will kill off free API access

Your favorite Twitter accounts and services may be shutting down soon.
Some of your favorite Twitter apps, automated accounts, tools, and services are no longer available. Twitter will now require anyone who creates the creative things that make the platform fun and enjoyable to pay up or face being banned.
Twitter’s official developer account, @TwitterDev, announced in the early hours of Wednesday morning that the company will no longer provide a free access tier to its API. Instead, a paid subscription to Twitter’s basic API tier will be available soon. And when will this occur? The following week. Feb. 9.
An API is a software interface that allows two applications to communicate with one another, and this one enables developers to access Twitter’s data and services via official channels. As a result, many developers have been able to create a wide range of free and paid products that improve the Twitter experience. Payment will almost certainly put an end to many of the free services and accounts.
