Password Strength Meter & HIBP Breach Checker
x402
Password Strength Meter & HIBP Breach Checker is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.020000/call, status unknown (last checked 2026-09-15).
Analyzes password strength via entropy, character classes, and crack-time estimates, then checks if it has appeared in known data breaches using HIBP k-anonymity lookup.

How this service works
Password strength meter + breach checker. Entropy, character classes, common patterns, crack-time estimates. Plus HIBP k-anonymity breach lookup.
Output
Returns an entropy value, character class breakdown (uppercase, lowercase, digits, symbols), crack-time estimate, flags for common patterns (dictionary words, keyboard walks, repeated chars), an overall strength rating, and a breach count from the HIBP k-anonymity lookup indicating how many times the password hash prefix has appeared in known breaches.
Example use cases
Example prompt
“Can you check how strong the password 'Tr0ub4dor&3' is — tell me its entropy, crack time estimate, whether it uses common patterns, and whether it's shown up in any known data breaches?”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/password-strengthWhen to prefer
Use this endpoint when you need both password strength analysis (entropy, crack time, pattern detection) and breach-database checking in a single call, rather than calling separate services. Ideal for registration flows, security audits, or any agent workflow that needs to validate a credential before use or storage.
Side effects
- Empty or missing password field returns 400 error
- Extremely long passwords may time out the entropy computation
- HIBP API unavailability may cause breach lookup to fail while strength metrics still return
- Payment not sent or insufficient USDC results in 402 Payment Required
