## 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 vextorium-nft-info-lookup-7498ec87 -d '<json body>'
```

Example prompt: Can you look up the details for Bored Ape Yacht Club token #1 on Ethereum — I want to know the current owner, collection name, token standard, and the metadata URI?

## When to prefer this

Use this endpoint when you need to look up on-chain NFT data for a specific token on EVM-compatible networks (Base, Ethereum, Arbitrum, Optimism, Polygon). It covers both ERC-721 and ERC-1155 standards and returns both on-chain info (owner, standard) and off-chain metadata in a single call, making it ideal for NFT verification, display, or enrichment workflows.

## Known failure modes

- Invalid contract address returns an error or null fields
- Token ID not found on the specified network returns empty/null metadata
- Unsupported network other than base/ethereum/arbitrum/optimism/polygon returns a validation error
- IPFS metadata URI that cannot be resolved returns null for the metadata field
- Rate limiting or payment failure returns an HTTP 402 or 429 error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

Returns a JSON object containing the NFT's collection name, symbol, owner wallet address, token standard (ERC-721 or ERC-1155), network, contract address, token ID, metadata URI (e.g. IPFS link), and a metadata object with name, description, image, and attributes if resolvable.
