Hi Federico D., clay doesn't use your personal cookie for privacy and security reasons but if you're needing higher accuracy, you can try phantom buster
If you run the ‘Enrich Person from LinkedIn Profile’ enrichment you’ll get both these fields of information. One nested within ‘Headline’ and the other within ‘Summary’
yes the Enrich Person costs 1 credit per profile (i.e. row it is run on) but you also get a ton of other information from the individual’s LinkedIn profile (education, experiences, awards etc.)
can’t provide any guarantees for Phantom Buster but I would do some more digging on them externally since LinkedIn generally has restrictions/requirements when it comes to scraping
Happy to answer that last one, Federico! When enriching, if it can't do it, that's because the profile doesn't exist otherwise it should return some data about the profile. Let me know if you run into any issues!
