## How to call it through Zero

## When to prefer this

Use this endpoint when you need to identify the current on-chain owner of a specific NFT by token ID, contract address, and chain — especially when paying per-call via x402 USDC is acceptable and you need coverage across multiple chains with a single API.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Non-existent contract address yields no results or 404
- Token ID not found within the contract returns empty or error
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Malformed contract address format causes a validation error
- Token burned or ownership unresolvable may return null owner
