How this service works
Checks whether a password appears in known breach corpora via the HIBP Pwned Passwords range API with k-anonymity: only a 5-char SHA-1 prefix leaves the edge, and the password is never stored, logged or echoed. Accepts a raw password or a caller-computed SHA-1.
Output
Returns a boolean indicating whether the password was found in known breach corpora, along with how many times it appeared across breached datasets. The full password never leaves the caller — only a 5-character SHA-1 prefix is transmitted to preserve k-anonymity.
Example use cases
User registration password safety gate
“Before letting a new user set their password, check if 'Summer2024!' has been found in any known data breaches — I want to reject compromised passwords at signup.”
Security audit of stored credentials
“I'm reviewing our service accounts — can you check whether the password 'P@ssw0rd123' shows up in any breach databases so I know if it needs to be rotated?”
Personal password hygiene check
“I want to know if the password I've been using for years, 'CorrectHorseBatteryStaple', has ever been leaked in a breach before I keep using it anywhere.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/password-breach-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a privacy-preserving breach check that never exposes the full password — it uses k-anonymity so only a 5-char SHA-1 prefix is transmitted. Prefer this over rolling your own HIBP integration when you want a simple, agent-payable API call without managing API keys or HIBP rate limits directly. Ideal for AI agents that need to enforce password hygiene at account creation or credential rotation workflows.
Side effects
- Invalid or malformed SHA-1 hash input returns an error
- Missing required body fields returns a validation error
- HIBP upstream service unavailability causes request failure
- Payment of 0.01 USDC not provided or rejected causes 402 response
- Rate limiting if too many requests are made in quick succession
