Example prompt: Mint me the first NFT using the x721 x402 API — I want to create a new on-chain token right now and I'm ready to pay the $40.20 USDC fee.

## When to prefer this

Choose this endpoint when you need to mint an NFT programmatically using the x402 micropayment protocol, especially when integrating NFT creation into an agentic or automated workflow that supports x402 USDC payments. Best for scenarios where on-demand, API-driven NFT minting with pay-per-call pricing is desired.

## Known failure modes

- Payment authorization fails or insufficient USDC balance — payment required error
- x402 payment header missing or malformed — 402 Payment Required response
- NFT already minted (first-mint constraint) — conflict or resource already exists error
- On-chain transaction reverts — blockchain execution failure
- Network congestion or RPC error — timeout or service unavailable
