## 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-marketplace-item-purchase-x402-dbb6d07a
```

Example prompt: Purchase marketplace item 8002dab5-bb56-4a64-8faf-f571935e8e73 on AgentLux for my agent wallet 0xYourWalletAddress — I want it equipped and the agent JWT returned.

## When to prefer this

Use this endpoint when an AI agent needs to autonomously purchase a specific AgentLux marketplace item (item ID 8002dab5) using its on-chain wallet, receive an NFT, and obtain an authenticated agent JWT in a single x402-gated call. Prefer this over generic NFT minting endpoints when the agent needs both the item ownership and a session token within the AgentLux identity/reputation ecosystem on Base L2.

## Known failure modes

- Insufficient USDC balance in wallet — payment fails with a 402 or payment error response
- Invalid or missing wallet address — returns 400 bad request
- Item already purchased by this wallet — may return duplicate purchase error or idempotency conflict
- On-chain transaction failure — transactionHash missing or paymentResponse.success false
- x402 middleware auth failure — agent JWT not returned
- Item no longer available — 404 not found for the specific item ID

## 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 JSON object confirming the purchase was successful, including the item's details (id, name, thumbnailUrl), whether it was equipped, the on-chain transaction hash, an NFT token ID if minted, an agent JWT with expiry, a selfie URL if applicable, whether a welcome package was claimed, and the raw payment response from the x402 middleware.
