Check an NFT token's owner when needed
Start a specific ownership lookup without turning the question into a manual research task.

Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Get NFT Owners
This tool retrieves the owner(s) for a specific nft token, supporting both erc721 and erc1155 tokens on ethereum and several layer 2 chains such as polygon, arbitrum, optimism, and base. it requires the contract address and tokenid, and returns a list of owner addresses along with an optional pagination key for further results.
Why this helps
Token ownership questions can get stuck while someone locates the right contract and token lookup.
- Use a supplied contract and token ID for a focused lookup.
- Summarize owner addresses returned by Alchemy.
- Support ownership checks for supported ERC-721 and ERC-1155 tokens.
Setup
Build it in a few focused steps.
- 1Connect Alchemy once in Notis.
- 2Create an automation for on-demand NFT ownership checks.
- 3In one instruction, ask Notis to retrieve and summarize owner details for the contract address and token ID supplied with each request.
- 4Pick the webhook trigger and choose where run reports go.
- 5Test with one real contract address and token ID.
Questions about this workflow
Can I check ownership without a token ID?
No. The action requires both the contract address and token ID.
Does this prove a person controls a wallet?

Get NFT Sales
This tool will retrieve nft sales data across various marketplaces. it allows users to query historical nft sales data with filtering options such as fromblock, toblock, order, marketplace, and limit in order to track nft sales activity, analyze historical data, monitor specific collections, and get real-time updates on nft transactions.

Get NFTs for Contract
This tool retrieves all nfts for a given contract address. it is designed to return a complete list of nfts from a specific nft collection by accepting parameters such as contractaddress (required), withmetadata (optional), pagesize (optional), and pagekey (optional). the tool is useful for analyzing collections, building nft marketplaces, and creating collection analytics.
Get NFT Owners
This tool retrieves the owner(s) for a specific nft token, supporting both erc721 and erc1155 tokens on ethereum and several layer 2 chains such as polygon, arbitrum, optimism, and base. it requires the contract address and tokenid, and returns a list of owner addresses along with an optional pagination key for further results.
Get Token Balances
This tool retrieves erc20 token balances for a specified ethereum address. it can either return balances for all tokens an address has ever interacted with or for a specific set of token contract addresses. it is useful for checking token balances for wallets, monitoring erc20 token holdings, portfolio tracking, and defi applications.
Get Token Metadata
This tool retrieves metadata for a given token contract address, including the token's name, symbol, decimals, and logo url if available. it is essential for applications that need to display token information, handle token transfers, or manage token listings.
Get Transaction Count
This tool retrieves the number of transactions sent from a specific address (also known as the nonce). it uses the eth gettransactioncount endpoint to return the transaction count for an address at a specified block tag (latest, pending, earliest, or a hex block number), which is essential for determining the nonce for subsequent transactions.
