I've designed a new tool using Observable : https://observablehq.com/@pac02/look-at-your-list-of-created-articles-with-the-xtools-page-ap
The tool takes the list of created articles using xtools created articles csv and calls the xtools page prose API for each article. It provides useful insights about the content of your list of created articles.
Is there any place where we can share tools using xtools APIs?
Nice! There is no such venue for external sites that I'm aware of. Typically tools are hosted on Toolforge – Wikimedia's own web hosting platform. From there they are automatically indexed on Toolhub, which is the 'official' place to advertise tools. I'm assuming migrating to Toolforge is probably a lot of work for you, but if you're able to use the observablehq framework or whatever it is, it would probably be worth your while. Beyond that, you can advertise your tools on-wiki just like you would any tool (WMF hosted or not). I'm not really sure the best place to do that, unfortunately. At any rate, I'm pleased to see the XTools API getting some usage :)
I should also mention the docs (which I see you're linking to) are no longer at readthedocs.org, but at XTools/API. I.e. https://xtools.readthedocs.io/en/3.6.6/api/page.html should be https://www.mediawiki.org/wiki/XTools/API/Page.
