## 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-artlu-workers-dev-e7794f0d -d '<json body>'
```

Example prompt: Send a test call to the x402 static test endpoint at artlu's Cloudflare Worker and confirm it goes through with a $0.001 USDC micropayment — I just want to verify the x402 payment flow is working.

## When to prefer this

Use this endpoint when you need a minimal, low-cost ($0.001 USDC) live test of the x402 micropayment protocol against a real Cloudflare Worker deployment. Ideal for validating x402 client libraries, payment flow integrations, or agentic payment pipelines without any meaningful side effects beyond the payment itself.

## Known failure modes

- Payment not attached or malformed x402 header returns 402 Payment Required
- Insufficient USDC balance causes payment failure
- Network error reaching Cloudflare Worker returns 5xx
- Invalid facilitator or payment channel results in rejected transaction
