Web3 Data Fetcher Tool (powered by Uniblock)
What is an AI Tool?
An AI tool is a feature or integration available to your AI agent that lets it access, retrieve, or act on external data in real time. By connecting to APIs or other data sources, AI tools expand what the agent can do - making it possible to fetch live web3 data, interact with blockchains, and much more, directly through natural language prompts.
What is the Web3 Data Fetcher Tool?
The Web3 Data Fetcher Tool, powered by Uniblock, allows your AI agent to access live and historical data from multiple blockchains and tokens using natural language commands. This tool lets you check token prices, wallet balances, transaction histories, NFT details, gas fees, and more, simply by describing what you want to know.
Below are the types of queries you can make and example prompts to use. All commands are in plain English - no code or blockchain expertise needed.

How to Use the Data in Your Workflow
All data returned by the Web3 Data Fetcher Tool comes as raw, structured data (not human-readable summaries). To make it actionable - like sending results in an email, displaying a report, or summarizing token balances - you should use another AI agent step after this one.
Example: Suppose you fetched wallet balances and want to send the summary by email. After getting the data, add a follow-up AI Agent with a prompt such as:
“Take the token balances output and summarize them as a plain English report I can send to my team by email. Format it as a short list, and include total USD value at the end.”
You can customize this step for any format you need—tables, charts, plain lists, etc.
Tip: The quality and completeness of the data you get may vary by model. Advanced models can handle more complex or ambiguous requests, troubleshoot errors, and return better-structured data. Simpler models will attempt exactly what you ask, one time—so if your prompt is vague or the data is tricky, you may get less robust results.
Additional Tips
Use clear and specific prompts (see examples above).
You can combine this tool with others (notifications, email, reports) to automate end-to-end web3 workflows.
If your agent supports context, you can reference wallet addresses or token names across multiple steps.
If you have more advanced needs, such as filtering by dates, combining different types of data, or creating custom notifications, simply describe what you want in plain English and the AI agent will translate that into the correct data fetch and processing steps.
