## 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 apinow-fun-hello-message-api-f45d2f05 -d '<json body>'
```

Example prompt: Send a hello request to APINow.fun and show me the personalized greeting message it returns along with the version and timestamp.

## When to prefer this

Choose this endpoint when you want to test or demonstrate a pay-per-call x402 tokenized API with a minimal, low-cost ($0.001 USDC) real call, or when you need a simple greeting/hello message from APINow.fun specifically. Best for prototyping micropayment API flows or verifying x402 payment infrastructure is working.

## Known failure modes

- Insufficient USDC balance — payment fails and no message is returned
- Network timeout — endpoint unreachable
- Invalid x402 payment header — 402 Payment Required error
- Malformed request body — 400 Bad Request
