## 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-random-vercel-app-4ca2b7ce -d '<json body>'
```

Example prompt: Pick a random number between 1 and 500 for me.

## When to prefer this

Use this endpoint when you need a random number generated server-side via a simple API call and are operating in an x402 micropayment context; suitable for lightweight randomization tasks where a $0.01 USDC cost per call is acceptable.

## Known failure modes

- Invalid range (min greater than max) — likely returns 400 Bad Request
- Missing required range parameters — returns 400 with parameter error
- Payment not provided or insufficient — returns 402 Payment Required
- Service unavailable — returns 500 or timeout from Vercel serverless function
