Answer a focused exposure question without pulling a whole portfolio.

Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
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.
Why this helps
Full wallet reports create noise when an audit only needs a few token contracts.
- Keeps audit output focused
- Supports selected contract addresses
- Cuts irrelevant data review
Setup
Build it in a few focused steps.
- 1Connect 21risk and Alchemy in the Notis portal.
- 2Create an automation for selected token balance checks.
- 3Tell Notis to retrieve balances for the wallet and token contracts named in the webhook and summarize exposure relevant to the audit.
- 4Choose a webhook trigger and report channel.
- 5Test with one wallet and token set.
Questions about this workflow
Can the query cover all tokens instead?
Yes. Ask Notis to retrieve all token balances for the address when a broad view is needed.
Are these balances live?
The action returns the balances available at query time.

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.
