How this service works
Breached password check: is this password in known data breaches, and how often? Send only the SHA-1 hash (never the password); just the first 5 characters reach Have I Been Pwned (k-anonymity). Up to 50 hashes per call.
Output
Returns breach exposure data for each submitted SHA-1 hash, including whether the password has appeared in known data breaches and how many times it has been seen across breach datasets. Uses k-anonymity so only the first 5 characters of each hash are transmitted to the underlying HIBP service.
Example use cases
New account password safety check
“Before I create this account, can you check if my password's SHA-1 hash — 8CB2237D0679CA88DB6464EAC60DA96345513964 — has ever shown up in a data breach?”
Bulk credential audit for IT team
“I need to audit a list of employee password hashes for breach exposure — check these three SHA-1 hashes for me: 5BAA61E4C9B93F3F0682250B6CF8331B7EE68FD8, 7C4A8D09CA3762AF61E59520943DC26494F8941B, 6367C48DD193D56EA7B0BAAD25B19455E529F5EE”
User login breach warning system
“When a user logs in, I want to warn them if their password is compromised — check if this SHA-1 hash AABBCC1234567890AABBCC1234567890AABBCC12 appears in any known breach databases.”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/password/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check password hashes against breach databases without exposing the actual passwords, leveraging k-anonymity for privacy. It supports up to 50 hashes per call making it efficient for batch checks. Prefer this over direct HIBP API access when you want a simple, pay-per-use integration without managing your own API keys, or when building into an agentic workflow that already uses x402 micropayments.
Side effects
- Invalid SHA-1 hash format (not 40 hex characters) causes validation error
- Exceeding 50 hashes per call results in rejection
- Network timeout if HIBP upstream is unavailable
- Malformed comma-separated hash list returns parsing error
- Hash with no breach history returns zero count (not an error)
