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
Wallet checks interrupt your work when you have to copy addresses into separate tools and remember to return with the answer.
- Review holdings from an inbound WhatsApp request.
- Keep the lookup and run report in one automation flow.
- Summarize the returned balances for quicker review.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Alchemy once in the Notis portal.
- 2Create an automation named Wallet Balance Check.
- 3Tell Notis to read an Ethereum address from the inbound message, retrieve its ERC-20 token balances, and summarize the returned data.
- 4Pick the New Message Received trigger and choose where run reports go.
- 5Test with one real WhatsApp message containing an address you are authorized to check.
Questions about this workflow
Can the automation read any wallet address from the message?
It can use an address supplied in the inbound message. Test with a valid Ethereum address and clarify the expected network or address format in your instruction if needed.
Will it send the result back as a WhatsApp reply?
This workflow uses Alchemy's balance lookup action. Choose a report channel for the run result; a WhatsApp send action is not included in the available events.

Get NFT Contract Metadata

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.
Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
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.
