## How to call it through Zero

```sh
zero fetch --capability nft-wallet-collection-rollup-live-12f81e4c
```

Example prompt: Can you pull up a live snapshot of all the NFT collections in wallet 0x1234...abcd on Ethereum — I want to see what they hold and flag anything that looks like a scam?

## When to prefer this

Use this endpoint when you need a real-time, always-fresh rollup of every NFT collection in a specific wallet — especially when scam detection or ownership verification is important and stale cached data is not acceptable. Prefer it over cached endpoints when the user needs an up-to-the-moment view of a wallet's holdings rather than a snapshot from the past 24 hours.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or non-existent wallet address returns no results or an error
- Wallet with no NFTs returns an empty collection list
- Network or RPC timeout causes delayed or failed response
- Payment not completed results in 402 response and no data

## How this service works

A freshly-fetched rollup of all NFT collections held by the specified wallet on the given chain, including collection-level details, ownership counts, and scam/risk signals — always fetched live (not cached).
