+1 to @Sburk017’s comment. Jesse Chen of Meta posted this update on Threads today:
Over the past few months, we’ve been building the Threads API to enable creators, developers and brands to manage their Threads presence at scale and easily share fresh, new ideas with their communities from their favorite third-party applications.
The API currently enables users to authenticate, publish threads, and fetch the content they posted through these tools – and soon, we will enable reply moderation and insights capabilities.
We are now testing with a small number of partners — grabyo, hootsuite, socialnewsdesk, sprinklr, sproutsocial, and techmeme — as well as a few independent developers. While we will limit access to the Beta at this time, we hope to make the API broadly available by the end of June.
