Streams Data Sources

更新日：
2026年6月26日

概要​

Each stream delivery contains two top-level fields:


  • データ — the dataset content. The shape of データ depends on the selected dataset type and chain client's structure for the given data. We do not modify the structure of the underlying data.
  • メタデータ — an object containing metadata about the stream and the current batch.

Metadata is always included in every delivery:


  • HTTP headers: Metadata fields are sent as HTTP headers on every delivery request.
  • Payload body: Metadata is included as a メタデータ object in the JSON payload body.
  • Filter function: The full payload (including メタデータ) is passed to your filter function when one is configured.

Note: Metadata is sent once per batch, not per individual data record.

ログ​

The data returned is an 配列 of arrays of log objects, as they appear within the ログ array in transaction receipts. The ログ data schema corresponds to event logs generated by smart contract transactions, documenting significant events, function calls, or other relevant activities occurring within smart contracts. This data is associated with the eth_getLogs JSON-RPC method, providing insights on smart contract interactions per block.

取引​

The data returned is an 配列 of arrays of transaction objects, as they appear in the 取引 array of block data. The 取引 data schema narrows data down to focus on transaction details, similar to each transaction object you would get when using the eth_getTransactionByHash method. It utilizes transaction hashes, returned from a method like eth_getBlockByNumber, to loop over each transaction hash and return its transaction object. This makes it easy to look up detailed transaction information.

Traces (debug_traceBlock)​

The data returned is an 配列 of arrays of trace data as returned by debug_traceBlock. その Traces (debug_trace) data source provides a granular, step-by-step look at transaction executions, including internal calls and state changes, which is critical for debugging and optimizing smart contracts.

Block with Receipts + debug_traces​

The data returned is an 配列 of objects containing a composite dataset with:


  • ブロック
  • receipts
  • traces (from debug_traceBlock)

If you want to retrieve an all-in-one data source for backfilling historical blockchain data, a data schema like Block with Receipts and debug_trace can retrieve block and transaction receipts, along with step-by-step transaction execution traces and internal transactions. This data source uses the eth_getBlockByNumber, eth_getBlockReceipts, and debug_traceBlock RPC methods.

Block with Receipts + trace_block​

The data returned is an 配列 of objects containing a composite dataset with:


  • ブロック
  • receipts
  • traces (from trace_block)

NOTE: This data source is an alternative to the Block with Receipts & debug_trace schema above. It utilizes the trace_transaction RPC method from Erigon, instead of using the debug API from Geth.

If you want to backfill historical blockchain data, a data schema like Block with Receipts and trace_block, is one solution. This data source uses the trace_transaction RPC method to retrieve transaction execution traces and internal transactions along with block and transaction receipt information using eth_getBlockByNumber, eth_getBlockReceipts RPC methods.

Note: Please review the chain specific documentation for the RPC method indicated above for more details about that chain's expected payload shape.
