## 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 agenttools-nft-wallet-portfolio-lookup-c624185e
```

Example prompt: Can you pull up all the NFT collections held by wallet 0x1234...abcd on Ethereum and show me how many tokens they own in each collection, sorted by quantity?

## When to prefer this

Use this endpoint when an agent needs a complete, sorted breakdown of all NFT collections held by a specific wallet in a single call, particularly for wallet profiling, due diligence, or enrichment workflows on Ethereum or Base. Prefer this over generic blockchain explorers when you need structured, agent-ready data without scraping. Pair with a wallet-snapshot endpoint for a full financial picture.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain value outside of 'ethereum' or 'base' returns a validation error
- Wallet with no NFTs returns an empty collection list
- Rate limiting or payment failure (x402) if credits are insufficient
- Network or upstream indexer timeout resulting in a 503 or partial response

## How this service works

Look up an address's NFT portfolio across collections: each collection held, quantity owned, sorted by size. The enrichment endpoint for agents profiling wallets — pairs with wallet-snapshot for the full picture. Use this when an agent needs to every NFT collection a wallet holds, in one call.

## Output

A list of NFT collections held by the queried wallet address, each entry including the collection name/identifier and the quantity of tokens owned, sorted in descending order by quantity. Supports filtering by chain (ethereum or base) and an optional limit on the number of collections returned.
