This is why apps like Boost, who never signed up for a subscription model are still functioning.

Updated rate limits going into effect over the coming weeks

Hi Devs,

Over the last few months, we’ve shared updates on our Data API Terms and Developer Terms. Shortly, we will begin enforcing the previously announced updated API rate limits. Rate limits will go into effect for all apps with usage above the free limit in the coming weeks, and some changes will be noticeable over the next 24 hours.

As we have shared, this will not impact non-commercial bots operating within free rate limits or moderator tools.

Free API access rates are as follows:

• 100 queries per minute per OAuth client id if you are using OAuth authentication
• 10 queries per minute if you are not using OAuth authentication

The vast majority of third-party apps and bots fall into the free usage category and should not see any disruptions. Our free rates account for bursts in usage.

For apps that exceed these limits, we have exempted select clients (for example, accessibility-focused apps like RedReader, Luna, and Dystopia), mod bots, and mod tools. If your bot or tool is affected unexpectedly, please reach out https://reddithelp.com/hc/en-us/requests/new?ticket_form_id=14868593862164.
