Meta is starting to bring the Threads API online, though it will still be some time before it’s widely accessible to developers. The company has begun testing its new developer tools with a handful of companies, Meta engineer Jesse Chen shared in a post on Threads.

According to Chen, whose post was first spotted by TechCrunch, the API is currently in “beta” but a wider rollout could come “by the end of June.” The initial group of companies testing out the beta version of the API include social media management platforms Sprinklr, Hootsuite, Social News Desk and Sprout Social. Meta is also working with tech news aggregator Techmeme and live video platform Grabyo. For now, it sounds like the API will primarily enable the publishing of content to Threads from these services, but Chen said there are also plans to “enable reply moderation and insights capabilities.”

Having an API could help Threads attract more publishers and power users, who often rely on third-party software for posting and analytics. Instagram head Adam Mosseri has previously expressed some reluctance to woo publishers, saying that his “concern” was that a dedicated API would “mean a lot more publisher content and not much more creator content.” (Mosseri has also said he doesn’t want to “amplify news on the platform.”)

But with 130 million users, Threads is starting to look more and more like a viable alternative to X, and offering professional-level tools is a good way to get publishers and brands to post more to the platform. Having an API could also, potentially, aid the company’s plans to support interoperability with Mastodon and the rest of the fediverse, though Meta hasn’t publicly discussed its API in that context,.
