I asked chatgpt to write a go program for this, this looks roughly correct (I have used both libraries before) obviously this won’t be enough for your particular use case. I imagine you can integrate an RSS feed to your site, however if you’re using something like hugo perhaps output it as a csv.

Super low effort but a good start I think:
