How this service works
Password strength estimator, score 0-4, zxcvbn-style heuristics, crack time, weak password detection. Returns score, feedback, estimated crack time. Accepts payment on Base or Solana — either network works.
Output
Returns a numeric strength score (0-4, where 0 is very weak and 4 is very strong), an estimated time-to-crack string, and actionable feedback/suggestions for improving weak passwords.
Example use cases
Example prompt
“How strong is the password 'Tr0ub4dor&3' — give me its score out of 4, estimated crack time, and any feedback on how to improve it.”

Endpoint
GEThttps://api.x402node.dev/password/strengthWhen to prefer
Use this endpoint when you need a programmatic, zxcvbn-style password strength score with crack time estimates and human-readable feedback — ideal for form validation flows, user onboarding security checks, or auditing stored passwords for weakness without rolling your own heuristics.
Side effects
- Missing password field in request body returns 400 error
- Empty string password may return score of 0 with no crack time
- Very long passwords may have unexpected behavior
- Payment failure returns 402 if USDC not provided
