WoW Classic API for Guilds

Hi,

I’m trying to make a website for our guild. I want to use the API to get information about the guild and the characters. But it seems like that this is not possible at the moment. When I try what I want with Guild/Character Data from the latest patch with addons, everything works fine. If I use a classic Guild/Character then nothing works.

Is the wow classic API already finished to get Guild and Character information?
When will it be finished?
Is there anything that won’t be possible compared to latest patch?

Thanks in advanced

The ONLY endpoints available for classic are the endpoints listed here World of Warcraft Classic API Endpoints

Blizzard does not provide API estimate times for future releases.

Also based on this I don’t think profile APIs will receive a classic version any time soon. https://classic.wowhead.com/news=294498/no-armory-profile-page-support-at-wow-classic-launch
