GET /breach-check/password

live

Check if a password has appeared in known data breaches using the HaveIBeenPwned Pwned Passwords API with k-anonymity — the full password is never transmitted, only a 5-character SHA-1 hash prefix — returns breach count and a risk classification so agents can enforce password policies without storing or exposing credentials.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
