## 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-protected-content-d48aa6d4
```

Example prompt: Can you fetch the protected content from x402tap.com — it requires a $0.001 USDC micropayment via the x402 protocol to unlock?

## When to prefer this

Use this endpoint when you need to demonstrate or test x402 micropayment-gated content delivery, or when an agent workflow requires accessing content behind a pay-per-request USDC paywall using the x402 protocol. Prefer this over traditional auth-gated content endpoints when the access model is per-call micropayment rather than API key or OAuth.

## Known failure modes

- Payment not included or invalid — returns HTTP 402 with payment requirements
- Insufficient USDC balance for the $0.001 fee — payment rejected
- Malformed payment header — authentication fails
- Network timeout — endpoint unreachable
- Invalid or expired payment token — access denied
