answers 402

List the known public data breaches that affected a domain, from the Have I Been Pwned breach catalogue. Returns normalized breach metadata (name, date, account count, data classes, stealer-log and verified flags) plus a summary. This is which known breaches touched the domain, not whether a specific account is compromised. Breach indicators, not a guarantee.
