How this service works
Password strength estimate: Entropy, common-password and pattern checks (sequences, years, Word123!), crack-time estimates and feedback. Never stored or logged. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
Returns a structured analysis including entropy bits, estimated crack time under various attack scenarios, whether the password appears in common-password lists, detected weak patterns (sequential characters, keyboard walks, year suffixes, Word123! structures), an overall strength rating, and human-readable improvement feedback. Passwords are never stored or logged.
Example use cases
Pre-registration password gate
“Before I let users set their account password, I want to check if 'Summer2024!' is strong enough — give me the entropy, crack-time estimate, and any pattern warnings so I can decide whether to accept it.”
Security audit of existing passwords
“I'm auditing some passwords from our old system. Can you evaluate 'P@ssword1' and tell me how weak it is, what patterns make it vulnerable, and roughly how fast it could be cracked?”
User onboarding strength feedback
“A user just typed 'qwerty123' as their new password — can you analyze its strength and give me specific feedback I can show them on why it's too weak and how to improve it?”
Technical details
Endpoint
POSThttps://tools.moneytools.dev/v1/password-strength?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a detailed, multi-dimensional password strength analysis that goes beyond simple length or complexity rules — specifically when you want entropy scores, crack-time estimates, pattern detection (sequences, years, common substitutions), and feedback suggestions in a single call. Prefer it over client-side zxcvbn-style libraries when you need a server-side audit trail-free check with consistent scoring logic, or when building an agent workflow that must evaluate password quality programmatically without storing the credential.
Side effects
- Missing or empty password field returns a validation error
- Password exceeding maximum length may be rejected
- Free tier exhausted (10/day) returns HTTP 402 requiring x402 payment or API key credits
- Network timeout on the endpoint
- Malformed JSON body returns a parse error
