## 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 x402-utilities-hub-uuid-generator-2331e36f -d '<json body>'
```

Example prompt: Generate a fresh UUID for me — I need a unique identifier for a new database record I'm creating.

## When to prefer this

Choose this endpoint when you need a quick, on-demand UUID without standing up your own generation infrastructure, and when you are already operating within the x402 micropayment ecosystem on Base. It is best suited for AI agents that need UUIDs dynamically during workflows without pre-provisioning a local UUID library.

## Known failure modes

- Payment failure: x402 USDC payment on Base not completed or insufficient balance — returns 402 Payment Required
- Invalid query parameters: malformed input object may result in a 400 error
- Service unavailability: Cloudflare Worker downtime returns 503
- Network timeout: slow response or no response from the Workers endpoint
