Inside a token holders response

A token holders response has one item per holder, 10 fields each, and pagination.total_count says how many holders there are: 386,723 for UNI at the end of 2025. Three fields carry a concentration study. Here is one item from the call behind the panel above, and what to do with each.

Blockchain data for dashboards and research

Each kind of dataset maps to an endpoint or two. Credit costs are per call unless a row says per item.

• Decoded event logs

  Every event a contract emitted over a block range, or every event with a given signature across all contracts, decoded with names and parameters. That is the raw material for protocol metrics.

  • Log events by contract0.01 credits per item
  • Log events by topic0.01 credits per item

• Holders and balances at any block

  Who held a token on a date, and what any address held then, priced that day. Run the same query at each month end for a panel dataset. Past blocks work on all Foundational chains.

  • Token holders0.02 credits per item
  • Historical token balances1 credit
  • Block heights1 credit

• Token prices over time

  Daily prices for any token over a date range, in any of 16 fiat currencies, to put event series and balances into USD.

  • Historical token prices1 credit

• Blocks and transactions

  Every transaction in a block, a single transaction with its decoded logs, or an address's full history, oldest first. Classification labels each of an address's transactions with a type and a category, so activity can be counted by kind: swaps, transfers, lending.

  • Transactions in a block0.1 credits per item
  • A transaction0.1 credits
  • Paginated transactions0.1 credits per item
  • Transaction classification+0.05 credits per item

Historical data API vs Dune

Dune is the place for SQL over whole chains. GoldRush answers narrower questions, about an address, a contract, an event or a block, over REST, including state at any past block.
