How this service works
Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.
Output
Returns a result object with a strength assessment of the submitted password, plus metadata about the evaluation. The exact format of the strength indicator (score, label, or detailed breakdown) is determined by the response schema's flexible result field.
Example use cases
Example prompt
“Check how strong the password 'Tr0ub4dor&3' is — tell me if it's weak, moderate, or strong.”

Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/password_strength?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, model-free password strength evaluation without relying on an LLM's potentially inconsistent judgment. Useful when you want a paid, auditable, per-call result for security tooling or compliance workflows.
Side effects
- Missing required 'password' field returns 400 or validation error
- Empty string password may return low strength or error
- Payment not provided or insufficient USDC balance returns 402
- Service unavailable returns 5xx error
