How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
A JSON object with a boolean 'breached' field indicating whether the password appeared in known breach datasets, and a 'timesSeen' integer showing how many times it was found across breach records (e.g. {"breached": true, "timesSeen": 52256179}).
Example use cases
Pre-registration password safety check
“Before I create my account, can you check whether the password 'Tr0ub4dor&3' has shown up in any known data breaches?”
Security audit of employee credentials
“I'm doing a security review — can you check if the password 'Welcome123' has been compromised in any breach and how many times it's been exposed?”
Personal password hygiene check
“I've been using 'iloveyou1234' for years — has it ever been found in a hacked database, and if so how bad is the exposure?”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/util/password-breach?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call password breach lookup without a monthly API subscription. Ideal for agents that perform occasional credential hygiene checks and want to pay only per query via USDC micropayment. Prefer this over direct HIBP API calls when already integrated into the x402 payment flow on Base, Polygon, or Solana.
Side effects
- Missing both sha1 and password query parameters — returns 400 bad request
- Invalid SHA-1 hash format — may return error or unexpected result
- Breach database unavailable — may return 503 or timeout
- Payment not received via x402 — returns 402 Payment Required
- Rate limiting if too many calls in quick succession
