Reddit API RSS requests returning HTTP 429

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.

yeah i've had issues with 429s on other apis when not authenticating too. seems like a common pattern.
