@rra sadly the client API is still a WIP but my colleague should be getting to it next week ish. I'll see if I can get a lil somethin done before then though.

technically it should be possible to do it witg curl, you just need to do the digest calculation and signing stuff with openssl or similar. Sadly I don't have ready examples of it cause we did it in js.

Here's how we do it so far: https://github.com/hyphacoop/social.distributed.press/blob/initial/src/server/apsystem.ts#L129
