## 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-stall-hello-endpoint-taiwan-0c19609a
```

Example prompt: Send $0.01 USDC via the x402 protocol to the Taiwan hello-402 stall and show me the signed timestamp it returns back.

## When to prefer this

Choose this endpoint when you need to test or demonstrate the x402 micropayment protocol with a live, real-money endpoint. It is ideal for verifying that an x402-compatible wallet or agent can successfully authorize and complete a $0.01 USDC payment and receive a gated response. Not useful for production data retrieval — this is a demo/testing stall.

## Known failure modes

- Payment not included or malformed x402 header returns HTTP 402 with payment requirements
- Insufficient USDC balance causes payment rejection
- Render hosting cold start may add latency or timeout on first request
- Invalid or expired payment token results in authentication failure
- Network issues with the Render deployment may cause 503 errors

## How this service works

## Output

A short JSON or text response containing a greeting message identifying the server as based in Taiwan, along with a signed timestamp confirming the time of the paid request. This serves as proof that the x402 micropayment was accepted and the endpoint responded successfully.
