Balance parser (token name and its amount) of the wallet in different networks with subsequent transfer of all data to Notion and Google Sheets

Hello, I need help from someone knowledgeable in the platform, as I have recently started automating some processes at work but I am still limited in my programming knowledge, etc.
I am willing to discuss the cost of assistance.
In short:
I need to create a parser for a specific balance (coin name in a crypto wallet network in all networks.
Preferably, when a new coin appears in a wallet in any of the networks, it automatically adds everything to Notion and Google Sheets.
Initially, I did a parser through scripts from the website using XPath, but then switched to API requests, but so far it is not working very well.
I will provide my disabled example.
