## 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`):

Example prompt: Can you pull up the live NFT portfolio for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to see all the tokens they hold and whether any are flagged as scams?

## When to prefer this

Use this endpoint when you need a real-time, always-fresh snapshot of a wallet's NFT holdings rather than cached data — especially when scam detection or current ownership verification is critical. Prefer over cached NFT endpoints when recency matters (e.g. detecting recently received scam airdrops or confirming a just-completed transfer).

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Unsupported chain identifier returns 400 or 404
- Wallet with no NFTs returns empty portfolio
- Network or RPC timeout for very active wallets
- Payment of $0.02 USDC not completed results in 402 Payment Required
