# Strale Password Strength Checker

> Strale Password Strength Checker is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0216/call, status unknown (last checked 2026-09-14).

Evaluates the strength of a given password and returns a structured assessment with scoring and audit trail

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability strale-password-strength-checker-a824b82e
```

Example prompt: Can you check how strong the password 'Tr0ub4dor&3' is — I want to know if it's secure enough to use for an account?

## When to prefer this

Choose this endpoint when you need a reliable, auditable password strength evaluation with a cryptographic audit trail — particularly useful in compliance-sensitive environments or when building AI-driven registration flows. Prefer it over ad-hoc regex checks or local libraries when you need consistent, independently tested scoring across environments.

## Known failure modes

- Missing required 'password' query parameter returns a validation error
- Empty string password may return a zero-score result or error
- Extremely long passwords may be rejected or truncated
- Network or service unavailability returns a 5xx error
- Invalid request method (e.g. POST instead of GET) returns 405

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a structured assessment of the password's strength, typically including a numeric score, a categorical rating (e.g. weak, fair, strong, very strong), and possibly feedback on what makes the password strong or weak. Each response also includes a cryptographic audit record with chain hashing for traceability.
