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-api-key-management-4fa632e3 -d '<json body>'

## When to prefer this

Use this endpoint when you want to switch from per-request x402 USDC micropayments to a prepaid API key model for accessing util.beauty utilities. Prefer this over direct per-request payment when making multiple calls in a short period, running automated agents, or when you want predictable billing without on-chain transactions per call.

## Known failure modes

- Invalid or missing request body fields — returns ok: false with error detail
- Insufficient USDC balance or failed x402 payment — returns payment required or authorization error
- Duplicate key creation attempt — may return conflict or existing key reference
- Rate limiting on key provisioning — returns 429 or equivalent error
- Malformed JSON body — returns 400 bad request
