There are rate limits and requests per month limits specified for all plans and listed for Free, Pro, and Pro PDF at the table here … Free OCR API
Other than exceeding those limits and receiving an error message in the response when attempting an OCR request, is there any way to retrieve what my current usage is so that I do NOT make the call just to receive an error? I’ve seen some APIs place usage metadata in a special response header, but it does not appear that such data exists in the OCR.space responses.
