MLS Listings - embed? api?

Hey Treepl People, quick question… have had my first request to do a realtor site, and they are requesting their listings be added to their site.

So, my question, does anyone have any experience with integrating MLS into a BC or better yet, Treepl site? Looking for some info as to the best embed feature/plugin. I can see plugins for WordPress and SquareSpace.

Even API integration would suffice, but an embed for now is probably what the client can afford at this time.

I see there is IDX as an option, but looking to see if anyone else has any other suggestions.

Thanks in advance,
