Help me find a plugin?

I have been searching but there are so many plugins it’s hard to sort through them all.
I’m looking for a plugin that will allow other bloggers to embed my content in their site.

The only one I found so far is this one: https://www.ads-software.com/extend/plugins/embed-article/

I prefer to use plugins that don’t require a service/api key though.. I prefer to be self sufficient in that sense.

Anyone recommend any other plugins?
