How this service works
Securly audits passwords against HaveIBeenPwned database leaks using k-Anonymity hashing locally.
Output
Returns a JSON object indicating whether the password is pwned (boolean), how many times it has appeared in breach datasets (count), a confidence level ('high'), a data freshness date (e.g. '2026-06'), any warnings, and a disclaimer. Example: {result: {count: 839482, pwned: true}, confidence: 'high', data_as_of: '2026-06'}.
Example use cases
Onboarding password strength gate
“Before I let this new user set their password 'Dragon99!', check if it shows up in any known breach databases and tell me if it's been pwned and how many times.”
Security audit of reused credentials
“We're auditing our team's credentials — can you run 'CompanyName2024' through the pwned password check so I know if attackers would recognize it from breach dumps?”
User-facing password reset advisory
“A user wants to reset their password to 'qwerty123' — check if that password has ever been compromised in a data breach before I allow it.”
Technical details
Endpoint
POSThttps://codepulse-api.hahavoid0.workers.dev/security/pwned-passwordWhen to prefer
Use this endpoint when you need a quick, pay-per-call breach check without managing API keys or subscriptions. Ideal for agents that need on-demand credential validation at low volume ($0.01/call). Prefer this over HIBP direct API when you want x402 micropayment-based billing on Base with no registration required.
Side effects
- Missing 'password' field in request body returns a validation error
- Empty string password may return unsupported or zero results
- Network timeout if upstream breach database is unavailable
- Unsupported password encoding or extremely long strings may fail
- Payment failure via x402 if USDC balance is insufficient
