## 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 x-pay-uuid-generator-1072fb17
```

Example prompt: Generate a fresh UUID for me using the X Pay API — I need a new unique identifier right now and I'm fine with the $0.001 USDC charge on Base.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use UUID generation with micropayment billing via x402 on Base/USDC, especially in agentic or automated workflows where you want programmatic, trustless, per-call billing without a subscription. It's ideal when you want a UUID from a neutral third-party source rather than generating one locally, or when auditability of UUID provenance matters.

## Known failure modes

- Payment not received or insufficient funds: request fails with 402 Payment Required
- Invalid HTTP method (e.g. POST): rejected, only GET/HEAD/DELETE allowed
- Network unavailability on Base: payment cannot be verified, request blocked
- Malformed query parameters: may return error or unexpected result
- Service downtime: endpoint unavailable, check sibling health/status endpoint

## How this service works

Pay-per-request utility APIs powered by x402 using USDC on Base.

## Output
