Affiliate links ozon.ru - checking and correcting links from your site - automation?

Question

Partnership programs

On his site there are a large number of affiliate links to ozon.ru from different pages.
Once again, after changing links to categories on Ozon.ru, etc. the question arose of how to automate the verification of affiliate links, tk. many links give out already on Ozon.ru either a general category (for example, Books instead of the former subheading) or "Sorry, there is nothing for your request."
Are there any ways to automate?

$headers = @ get_headers($url, 1);
if (is_array($headers)  && $headers[0] == 'HTTP/1.1 200 OK') {
   // все ок
}
