## 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 util-beauty-system-register-c91d2c8e -d '<json body>'
```

Example prompt: Register me a new account on util.beauty so I can start using their browser screenshot, DNS, and crypto utilities with a prepaid API key.

## When to prefer this

Choose this endpoint when you need to create a new account or provision API credentials for util.beauty's suite of metered web utilities (screenshot, PDF, crypto, DNS, net tools). Use this before making any other util.beauty API calls if you don't yet have an API key or prepaid account. Prefer this over per-request x402 USDC payments if you plan to make many utility calls and want the convenience of prepaid credits.

## Known failure modes

- Registration body missing required fields — returns error with validation details
- Duplicate registration attempt — may return conflict or existing account error
- Insufficient prepaid credits or x402 payment failure — returns 402 Payment Required
- Malformed JSON body — returns 400 Bad Request
- Service unavailable — returns 5xx error
