## 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 api-x402node-dev-6498688c
```

Example prompt: Check if the password 'MyP@ssw0rd!' passes our enterprise policy — minimum 10 characters, must have uppercase, lowercase, at least one digit, and one special character.

## When to prefer this

Use this endpoint when you need server-side password policy validation with configurable rules, especially for enterprise security workflows where specific character class and length requirements must be enforced programmatically without writing custom validation logic.

## Known failure modes

- Missing password input returns validation error
- Invalid rule configuration (e.g. non-numeric min length) returns 400 error
- Empty password string fails all rules
- Payment failure returns 402 error

## How this service works

Password policy validator, configurable rules, min length, uppercase, lowercase, digit, special, enterprise password policy check. Accepts payment on Base or Solana — either network works.

## Output

Returns whether the password passes or fails the configured policy, along with details on which specific rules (min length, uppercase, lowercase, digit, special character) were satisfied or violated.
