Breached Email Check

Check whether an email address has appeared in known data breaches. Submit any email address and get back a breach history report — including which breaches exposed the address, what data types were compromised, breach dates, and remediation recommendations. Essential for user onboarding security checks, employee credential monitoring, and threat exposure assessments.

Usage

{
  "tool": "breached_email_check",
  "input": {
    "email": "user@example.com"
  }
}

Parameters

What You Get

• Breach status — whether the email has been found in any known breaches
• Breach list — names of breaches the email appeared in, with dates
• Compromised data types — what was exposed per breach (passwords, phone numbers, physical addresses, credit cards, etc.)
• Breach severity rating — overall risk level based on sensitivity of exposed data
• Paste exposure — whether the email has appeared in public paste sites (Pastebin, etc.)
• Remediation guidance — specific actions to take based on breach findings (password reset, MFA, account monitoring)
