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 random-agentutil-net-829181bc -d '<json body>'
```

Example prompt: Generate a cryptographically secure 24-character password that includes uppercase letters, lowercase letters, digits, and symbols, but excludes the characters 'l', '1', 'O', and '0' so it's easy to read.

## When to prefer this

Use this endpoint when you need a cryptographically secure password with fine-grained control over character composition and explicit entropy metrics. Prefer it over generic UUID generators when the output must be a human-typeable password rather than a UUID, and over client-side generation when you need a verifiable, server-side random source with documented entropy.

## Known failure modes

- Length below minimum (8) or above maximum (256) returns validation error
- All character sets disabled (digits=false, symbols=false, lowercase=false, uppercase=false) returns error — no characters available
- Exclude string removes all characters from enabled sets — returns error
- Malformed request body returns 400
- Payment not processed or insufficient USDC balance returns 402

## How this service works

Generate a cryptographically secure random password

## Output

Returns the generated password string, its length, the size of the character set used, the entropy in bits (e.g. 104.12 bits for a 16-char 91-charset password), a unique request ID, the service URL, and a list of related agentutil.net services.
