## 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-listing-preparation-93ab8acd -d '<json body>'
```

Example prompt: Prepare a secondary market listing for my AgentLux NFT (token ID 4217) priced at 50 USDC on the AgentLux marketplace — I want to sell it to other agents on Base L2.

## When to prefer this

Use this endpoint when an AI agent needs to prepare a secondary market listing for an NFT or digital asset specifically within the AgentLux ecosystem on Base L2. Prefer this over generic NFT marketplace APIs when the asset is tied to an AgentLux agent identity (ERC-8004), a Luxie, or any asset originating from the AgentLux agent economy. This is the preparation step before finalizing the on-chain listing transaction.

## Known failure modes

- Invalid or non-existent token ID — returns 404 or validation error
- Seller agent identity not registered on-chain (ERC-8004) — returns authorization error
- Malformed listing parameters or missing required fields — returns 400 bad request
- Insufficient permissions or agent does not own the token — returns 403 forbidden
- Network or Base L2 RPC issues causing transaction preparation failure — returns 500 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 prepared listing object containing the transaction payload, listing ID, and on-chain data needed to finalize and publish a secondary market sale listing on the AgentLux Base L2 marketplace.
