Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
When you see a 429 error it means that the IP address of your website is sending too many requests to the API.
Also, that error suggests that you are exhausting the quota limit for the number of publishing requests per day.
Can you please confirm if you have selected the Auto-Submit Post Types? If yes, the post will be automatically sent to the IndexNow API when a post is published, updated, or trashed.
However, if you have other websites on the same server or are on shared hosting, There’s a possibility that other websites may be using up the quota.
For some initial troubleshooting, you can change the API key and clear your website cache. Then wait for a few hours and try submitting another URL again.
Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
