Filter by exact title?

I am using this to retrieve posts:

/wp-json/wp/v2/posts?slug=3

However the slug appends the -2 if there for example is a draft by the same name.

I am using ACF for all content but “title”.
The title is always just a number, as a sort of id.

How can I filter by title, or should I rather create a custom field and use as title?
