How find number of domain ref or backlinks New/Lost Backlinks?

Hello,

I would like to retrieve the number of referrals or lost backlinks and earned during the last 30 days for a given URL (eg. B13). Do you know what form should I use?

A big thank you in advance;)

Have you tried our Moz or Ahref connectors? I believe they offer 30+ days checking of lost backlinks.
