How this service works
Score a password's strength: character-set size, entropy bits, a 0–4 rating, and an estimated offline crack time. The password is never stored or logged.
Output
Returns the password's character-set size, entropy in bits, a numeric strength rating from 0 (very weak) to 4 (very strong), and an estimated time to crack the password offline. The password is never stored or logged.
Example use cases
Example prompt
“How strong is the password 'Tr0ub4dor&3'? Give me its entropy, character-set size, 0–4 rating, and how long it would take to crack offline.”
Technical details
Endpoint
POSThttps://agent402.tools/api/password-strengthWhen to prefer
Use this endpoint when you need a quick, privacy-safe server-side password strength evaluation that returns entropy bits, character-set size, a standardized 0–4 rating, and a crack-time estimate — particularly when you want a consistent scoring model without implementing your own entropy calculator.
Side effects
- Missing or empty password field returns a validation error
- Extremely long passwords may cause processing delays or be rejected
- Non-string password values may return a type error
- Payment failure (x402) if USDC balance is insufficient or payment not attached
