429 Too Many Requests returned

Hello, 

I'm currently encountering the following error when using your PDF service API

429 Too Many Requests returned

It seems that I am hitting the rate limit imposed on my account. Could you please provide more details about the current rate limits applicable to my usage?

Additionally, I would like to know if it's possible to increase the rate limit, either temporarily or permanently, to better accommodate my use case. If so, could you please let me know the process or requirements to request such an increase?

Thank you in advance for your assistance.

Best regards,
