## When to prefer this

Choose this endpoint when a user specifically wants to purchase a Machine Relic Genesis ERC-721 NFT on Base mainnet from Dank i Halden AS. It is the only endpoint for this specific collection and handles both reservation and automatic minting post-payment. Prefer it over generic NFT marketplaces when targeting this exact collection programmatically with a known recipient wallet.

## Known failure modes

- Invalid or malformed recipient address (not a valid 0x EVM address) returns an error
- USDC payment not observed within expected window causes minting to stall or fail
- NFT supply exhausted — no more genesis relics available to reserve
- Network or RPC issues on Base mainnet causing transaction failure
- Duplicate purchase attempt for an already-reserved token

## How this service works

Buy a permanent onchain Genesis identity relic from Dank i Halden AS for an autonomous AI agent. Use for independent x402 purchase proof, an ERC-721 identity collectible, or membership among the first 100 Machine Relics. Pays $0.05 USDC on Base; the NFT mints gaslessly to the recipient.

## Output

Returns a JSON object confirming success, the reserved tokenId, tokenURI (metadata URL), purchaseId, contract address, revenueWallet, price, network (base-mainnet, chainId 8453), a receiptUrl for on-chain verification, and a poll URL to check minting finalization status after USDC settlement.
