## 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 x402demo-nft-protected-content-5ddefedd -d '<json body>'
```

Example prompt: Can you fetch the protected NFT content from the Base network demo endpoint — I'm okay paying the 0.1 USDC micropayment to unlock it via x402.

## When to prefer this

Use this endpoint when you need to access content that is specifically gated behind the x402 micropayment protocol on Base, and are testing or integrating x402-based paywalled NFT content flows. Best suited for developers evaluating x402 payment-gating mechanics on Base NFTs or agents that need to retrieve a specific piece of Base NFT content behind a per-call micropayment.

## Known failure modes

- Payment not authorized or x402 header missing — returns 402 Payment Required
- Insufficient USDC balance — payment fails and content is not returned
- Invalid or malformed payment proof — server rejects the request
- Network timeout or server unavailability on the demo host
- Base network connectivity issues affecting NFT data retrieval
