Overview

  • Dataset ID: 0111 - Internal Transactions
  • Description: Internal transactions (call traces) from debug_traceTransaction. Response rows mirror blockdb_evm.b0111_internal_transactions_v1 (hex strings without 0x for BYTEA fields in JSON).
  • CSV Sample: Download
  • JSON Sample: Download

​
Parameters

​
chain_id
number
required
Target EVM network. See the Chain enumeration for supported values.

​
Range Filters (mutually exclusive)

​
from_block
number
Starting block number (inclusive) for the query. Use with to_block.
​
to_block
number
Ending block number (inclusive) for the query. Use with from_block.
​
from_timestamp
string
Starting timestamp (ISO-8601). If it falls between blocks, the next block after this timestamp is used. Use with to_timestamp.
​
to_timestamp
string
Ending timestamp (ISO-8601). If it falls between blocks, the last block before this timestamp is used. Use with from_timestamp.
Validation rule:
You must provide either a block range, a time range, or explicit selectors.
Providing more than one option (e.g., both ranges or ranges plus selectors) results in HTTP 400.
Providing none results in HTTP 400.

​
Direct Selectors

​
block_numbers
number[]
Explicit set of block numbers. Mutually exclusive with tx_hashes.
​
tx_hashes
string[]
Filter by parent transaction hash (hex string, 32 bytes, no 0x prefix). Returns all call traces for those transactions. Mutually exclusive with block_numbers.

​
Address & Type Filters

​
from_address
string
Filter by caller address (hex string, 20 bytes, no 0x prefix).
​
to_address
string
Filter by callee address (hex string, 20 bytes, no 0x prefix). Failed CREATE/CREATE2 may have null to_address and are excluded when this filter is present.
​
call_types
string[]
Filter by call type: CALL, DELEGATECALL, STATICCALL, CREATE, CREATE2. Omit to return all types.
​
tx_success
boolean
Filter by underlying transaction success (true = success, false = reverted). Omit to return traces for both.

​
Pagination Controls

​
limit
number
default:"250"
Recommended default 250; maximum 1000 to stay under ~10 MB responses.
​
cursor
string
Pagination cursor from a prior call.

​
Response Fields

​
Meta

​
meta
object
Echo of request metadata applied to the response.
​
meta.chain_id
number
EVM chain ID echoed from the request.
​
meta.request_window
object
Pure echo of the window you sent (from_block/to_block/from_timestamp/to_timestamp); unset bounds are null.
​
meta.resolved_window
object | null
The concrete window the query actually executed against, after resolving the request. For a block range on a time-bucketed endpoint (OHLC/VWAP/VWAP-aggregate/fiat VWAP), from_timestamp/to_timestamp hold the resolved timestamp window (and from_block/to_block echo your request). For a time range on a block-keyed endpoint, from_block/to_block hold the resolved block range (and the timestamps echo your request). null for selector-only requests (no window). No extra database work is done — these are the values the query already computed.
​
meta.resolved_window.from_block
number | null
Resolved/echoed start block of the executed window.
​
meta.resolved_window.to_block
number | null
Resolved/echoed end block of the executed window.
​
meta.resolved_window.from_timestamp
string | null
Resolved/echoed start timestamp (ISO-8601) of the executed window.
​
meta.resolved_window.to_timestamp
string | null
Resolved/echoed end timestamp (ISO-8601) of the executed window.
​
meta.filters
object
Filter parameters echoed from the request (addresses, call_types, tx_success, pagination state, etc.).

​
Data

​
data
object[]
Array of internal transaction (call trace) records, ordered by block, tx index, and trace address.
​
data.block_number
number
Block number of the parent transaction.
​
data.block_time
string
UTC timestamp of the block (ISO-8601).
​
data.tx_index
number
Zero-based index of the parent transaction within the block.
​
data.trace_address
string
Position in the call tree (e.g. "0", "0.0", "0.1").
​
data.call_type
string
One of: CALL, DELEGATECALL, STATICCALL, CREATE, CREATE2.
​
data.from_address
string
Caller address (hex string, 20 bytes, no 0x prefix).
​
data.to_address
string | null
Callee address (hex string, 20 bytes); null for failed CREATE/CREATE2.
​
data.value_wei
string
Native value transferred in this call, in wei (string to preserve precision).
​
data.gas
string | null
Gas allocated for this call (string to preserve precision); null when disabled from indexing.
​
data.gas_used
string | null
Gas consumed by this call (string to preserve precision); null when disabled from indexing.
​
data.input
string | null
Calldata for this call (hex string, no 0x prefix); null when disabled from indexing.
​
data.output
string | null
Return data from the call (hex string, no 0x prefix when present); null when disabled from indexing or if the call reverted or return data is absent in the source trace.
​
data.error
string | null
Error message if the call reverted; null otherwise.
​
data.tx_success
boolean
Success of the underlying parent transaction that produced this internal call.
​
data._tracing_id
string
Internal tracing ID for observability (hex string, no 0x prefix); unique per row.
​
data._created_at
string
Record creation timestamp, e.g. "2025-11-11T18:42:15.123Z".
​
data._updated_at
string
Last update timestamp in the same format.

​
Envelope Fields

​
cursor
string | null
Cursor token for pagination.
​
page_count
number
Number of records returned in data.
