## 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 public-zapper-xyz-fabbd173 -d '<json body>'
```

Example prompt: Can you pull up the full metadata for token ID 7495 in the Bored Ape Yacht Club collection at 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum mainnet (chain ID 1) — I want to see its traits, estimated value, last sale price, and any media?

## When to prefer this

Use this endpoint when you need rich, structured metadata for a single specific NFT token — including traits, valuation, last sale, and media — especially when working with EVM-compatible chains like Ethereum mainnet or Base. Prefer this over generic blockchain RPC calls when you need aggregated market data (floor price, estimated value) alongside on-chain metadata in a single response.

## Known failure modes

- Invalid or unrecognized collectionAddress returns empty or null nftTokenV2 object
- tokenId not found in the collection returns null data
- Unsupported chainId returns an error or empty response
- Malformed 0x address causes a validation error
- NFT has no media or traits, resulting in empty arrays
- Payment failure due to insufficient USDC balance returns a 402 error

## How this service works

Enterprise grade onchain data across 60+ chains - token prices, NFTs, portfolios, onchain search, Farcaster and more.

## Output

Returns an NFT token object including its name, description, traits array (attribute name/value pairs), holder information, last sale price in USD, media assets (images, animations, audio), collection name and symbol, collection floor price in USD, and estimated value in USD
