## 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 x402-alchemy-com-aa28db16 -d '<json body>'
```

Example prompt: Can you get me the full list of wallet addresses that currently own tokens from the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum mainnet, including how many tokens each wallet holds?

## When to prefer this

Use this endpoint when you need a comprehensive list of all current holders of a specific NFT contract — ideal for airdrop targeting, snapshot voting, ownership analytics, or verifying collection distribution. Prefer this over wallet-centric NFT endpoints when the starting point is a contract address rather than a wallet address.

## Known failure modes

- Invalid or non-existent contract address returns empty or error response
- Unsupported chain network returns 400 or 404
- Rate limiting or payment failure returns 402 or 429
- Contract is not an NFT contract returns empty owners list
- Pagination key mismatch or expiry causes incomplete results

## How this service works

Returns the owners of a given NFT contract across supported chains.

## Output

A paginated list of owner wallet addresses for the specified NFT contract, optionally including the number of tokens held per wallet, plus a page key for fetching subsequent pages.
