Hello,
Thank you for contacting Rank Math and sorry for any inconvenience caused.
This error suggests that you are exhausting the quota limit for the number of publishing requests per day.
I can suggest that you request more quota to serve the requests that your site is making by following the steps on the link below:

Looking forward to helping you. Thank you.
Hi Kamlesh,
This is a brand new API setup so no requests have been made previously… Is there a rough figure of how many requests the quota should be set to? Please refer to the screenshot provided in the sensitive data field.
Thanks for your help
Hello,
The instant indexing requests are also made when you edit or update any new or old posts. If the limits are getting maxed out, then it can be caused due to making changes to any old posts and updating them.
Could you please go to the Google API Console and select Quotas, then please share the screenshot of it here? You can use this tool to take screenshots as well.
You can also add it in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Looking forward to helping you.
Thank you.
