How do I get the shorturl if longurl already exists in YOURLS? API (PHP)

[pftnhr]

I would like to dynamically create short URLs in a blog to use them as a permalink for the posts. This also works when creating them. However, since the script is executed every time the blog is reloaded, I only get an empty JSON array after the short URL has been created in YOURLS, so the short URL is no longer stored in the post.

I would now like to query via API (PHP) whether the long URL is already in the YOURLS database and if so, I would like to get the short URL back. Neither in the documentation, nor here in the discussions or on Stackoverflow could I find an approach that helps me, so I ask here.

Have I missed something? Is this even possible?

Many thanks in advance!
