Verify NFT ownership from incoming requests
Turn ownership questions into a quick, repeatable webhook check.

Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
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
Ownership verification slows down when requests arrive through different channels.
- Responds quickly to ownership requests
- Supports multiple token standards
- Creates an auditable report
Setup
Build it in a few focused steps.
- 1Connect Alchemy in Notis once.
- 2Create an automation for owner verification.
- 3Tell Notis to read contract address, token ID, and network from webhook data, then report owners or missing inputs.
- 4Pick a Notis webhook trigger.
- 5Choose a report destination and test with one real request.
Questions about this workflow
Does it support ERC1155 ownership?
Yes. The action supports ERC721 and ERC1155 ownership lookups.
What if the request omits the token ID?
Notis should report the missing token ID and skip the lookup.

Coda Document Deleted Trigger
Triggers when a Coda document is deleted.
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.
New Coda Document Trigger
Triggers when a new Coda document is created.
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.
New Coda Page Trigger
Triggers when a new page is added to a Coda document.
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.
Specific Coda Page Updated Trigger
Triggers when a specific page within a Coda document is updated.
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.
