How to know when a particular verse of the Bible have been or will be part of the Liturgy of the Word? (Catholic) Is there a way to know (perhaps through an online database) when a particular verse of the Bible have been or will be read in Mass (if ever)? It could be under any rite (ordinary, extraordinary, Maronite, etc).

There are plenty of websites where you can check the particular readings of a given day (e.g. here and here), but the format in which these are presented are not easy for searching, or they cover a short period. But clearly, these websites are being sourced from somewhere so there information, in principle, is out there.

The ideal resource would be one where you would input a verse, and obtain in return exact dates when that verse has been read or will be read.

PS: why would this be useful? Well, say you have a blog of biblical commentary and have reflections of a particular verse. You might want to publish the text when it coincides with the particular day it is read in Mass.
Divinum Officium (GitHub repository), written in Perl, can do this. It contains data files for the Mass in several languages. Bible verses begin with a "!" (e.g., "!Num 17:8"), so you can easily search those files for verses. Divinum Officium generates a liturgical calendar, too.
