andypiper

Do you mean you’re trying to access Threads’ ActivityPub endpoint(s)?

I’m pretty certain that you have to use signed requests, and bear in mind that not all users have federation enabled.

I just confirmed that by using the fedify CLI to test. Running fedify lookup andypiper@threads.net fails, but with fedify lookup -a andypiper@threads.net (which spins up a local server and performs authenticated requests) I get back JSON from the WebFinger endpoint.

You’ll probably get some folks able to share their experiences integrating / testing with Threads federation in some of the Fediverse Developers related Matrix rooms.
