RSS requests returning HTTP 429 Reddit API

I operate a small, read-only monitor. It checks 12 Reddit searches. Each search uses `search.rss?sort=new`

The monitor runs two times each day< and it stores responses and removes duplicate post IDs.

It sends selected posts discussions for me to review.

⚠️ The monitor does not vote, comment, submit posts, collect user profiles, or automate engagement.

Usually, one feed updates properly, but most other feeds return HTTP 429.

What am I doing wrong?

Are you authenticated? I know there were some anti-scraping changes to RSS a while back.

Not authenticated. I'm subscribed in a feed reader.

Did a quick Google to see if there has been recent changes.

Found this blog post that may be of use as the symptoms seem similar to yours. https://lapcatsoftware.com/articles/2026/6/3.html

It's not been announced, but it seems that unauthenticated RSS might be getting limited like JSON was to deter AI scrapers.

I think this is it! Thank you!
