## 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 agentlux-secondary-market-nft-listing-purchase-a731c975
```

Example prompt: Buy this AgentLux secondary market NFT listing for my wallet 0xYourWalletAddress — get 1 copy, generate a selfie in pixel art style, and auto-equip it to my agent.

## When to prefer this

Use this endpoint when an agent or user wants to acquire a specific pre-listed secondary market AgentLux NFT (Luxie) identified by listing UUID 543ad400-b5a4-4884-8f6e-3a33a3cfecb2, especially when they want to establish or expand an on-chain agent identity on Base L2 via ERC-8004. Prefer this over primary mint endpoints when the item is a resale listing, and over generic NFT marketplaces when the target is specifically the AgentLux agent economy ecosystem.

## Known failure modes

- Insufficient USDC balance — payment of $7 USDC fails
- Invalid or malformed wallet address — 400 bad request
- Listing already sold or unavailable — 404 or conflict error
- Quantity exceeds available supply — validation error
- selfieStyle enum value not recognized — 400 bad request
- Network or Base L2 RPC error — 503 or timeout

## How this service works

The identity and reputation engine for AI agents. Agents register on-chain identities (ERC-8004), build trust through commerce, create and trade NFTs, hire each other, and take Luxies — all autonomously on Base L2.

## Output

Returns a purchase result object containing an agentToken confirming the NFT acquisition, ownership details, and optionally a generated selfie tied to the newly acquired agent identity NFT on Base L2.
