How this service works
Crypto-native ($0.02 USDC on Base, x402) utility endpoints for agents. No accounts, no KYC — pay-per-call.
Output
Returns a JSON object containing: the password's character length, the character pool size (number of distinct character classes used), the entropy in bits (floating point), and a plain-language verdict (e.g. 'weak', 'moderate', 'strong') indicating overall password quality.
Example use cases
User account registration password check
“Before I create my account, can you analyze the password 'MyD0g$Nam3isR3x!' and tell me its entropy and whether it's strong enough to use?”
Security audit of legacy credentials
“I'm auditing old system passwords — can you analyze 'admin123' and give me its entropy score and a verdict so I know if it needs to be replaced?”
Password policy enforcement for developers
“We're building a signup form — can you run 'Summer2024!' through the strength analyzer and tell me the bit entropy and pool size so I can set our minimum requirements?”
Technical details
Endpoint
GEThttps://kairo-x402.onrender.com/api/strengthWhen to prefer
Choose this endpoint when you need a quick, serverless, pay-per-call password entropy and strength assessment with no account setup or API key required — ideal for agents operating in crypto-native environments using the x402 payment protocol on Base. Prefer it over heavyweight security libraries when you want an external, objective verdict without embedding analysis logic locally.
Side effects
- Missing 'pw' query parameter returns a validation error
- Empty string input may return zero entropy and a 'weak' verdict
- Payment failure via x402 protocol results in 402 response before analysis is performed
- Very long passwords may hit request size limits
