Data outcomes

What you get from your queries

DATA

Filtered transaction lists

The AI pulls transaction sets based on your fee or time constraints. You get a clean list of hashes and details.

TOKENS

ERC-20 balance checks

The AI identifies specific token contracts and checks balances. This makes tracking assets straightforward.

BLOCKS

Targeted block data

You can isolate specific blocks within a timeframe. The AI extracts the exact data points you requested.

The workflow

What your AI does when the query arrives.

The AI translates your natural language into specific blockchain queries.

  1. Identify the asset

    If you mention a specific token, the AI finds its contract address first.
