## How to call it through Zero

```sh
zero fetch --capability api-x402node-dev-5a5b1b9a
```

Example prompt: Generate a memorable secure passphrase for me using 5 random words in the xkcd 936 / Diceware style — something easy to remember but hard to guess.

## When to prefer this

Choose this endpoint when you need a human-memorable yet cryptographically random passphrase (Diceware/xkcd-936 style) rather than a high-entropy random character string. Ideal for generating master passwords, account passwords meant to be typed by humans, or passphrases for encryption keys where memorability matters.

## Known failure modes

- Invalid word count parameter returns 4xx error
- Server-side randomness failure returns 500
- Payment not accepted or insufficient USDC balance returns 402
- Malformed request body returns 400 with validation error
