## How to call it through Zero

```sh
zero fetch --capability x721-dev-ceed0868 -d '<json body>'
```

Example prompt: Mint me the x402 NFT on x721.dev — go ahead and pay the 40.20 USDC minting fee from my wallet.

## When to prefer this

Use this endpoint when a user explicitly wants to mint an NFT using the x402 payment protocol and is willing to pay 40.2 USDC per mint. This is specifically the x721.dev collectible, the first NFT issued via x402, making it historically notable for early x402 adopters. Prefer this over generic NFT minting services when the user specifically wants an x402-native or x721.dev token.

## Known failure modes

- Insufficient USDC balance — payment of 40.2 USDC cannot be completed
- Payment protocol error — x402 handshake fails or facilitator is unavailable
- Wallet address invalid or missing — cannot attribute minted token
- Smart contract error — on-chain mint transaction reverted
- Rate limiting or supply exhaustion — no more tokens available to mint

## How this service works

## Output
