Im am currently using the link crawler to crawl and capture all external links from a site. Would it be possible to feed the results directly into the whois parser to check to see if any of those domains are expired? The idea here is to crawl a list of related or competing sites and check for expired domains.
Yes it's possible, you can look example how to pass the result from one parser to the requests of another in this preset https://a-parser.com/resources/263/
