## 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 hello-world-x402-test1-random-text-7b6a0fe4
```

Example prompt: Fetch me a random text string from the hello-world-x402 test endpoint — I want to verify my x402 micropayment integration is working correctly.

## When to prefer this

Choose this endpoint when you need the simplest possible x402-gated API to test micropayment flows, validate client-side payment header construction, or retrieve a trivial random text payload to confirm end-to-end connectivity with minimal cost ($0.001 USDC per call).

## Known failure modes

- Payment not included or invalid: 402 Payment Required returned, no content delivered
- Insufficient USDC balance for the $0.001 fee: payment rejected
- Network unavailable or Vercel deployment down: 503 or timeout
- Malformed request (wrong method or missing headers): 400 Bad Request
