​
Description

Retrieves raw EVM logs (event emissions) enriched with provenance metadata.

​
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 logs by parent transaction hash (hex string, 32 bytes, no 0x prefix). Mutually exclusive with block_numbers.

​
Contract & Topic Filters

​
contract_addresses
string[]
Filter by emitting contract address (hex string, 20 bytes, no 0x prefix).
​
topic_zeros
string[]
Filter by the primary event topic. Anonymous events have topic_zero = null.

​
Pagination Controls

​
limit
number
default:"250"
Recommended default 250; maximum 1000 to stay under ~10 MB responses.
​
cursor
string
Opaque pagination cursor supplied by a previous response.

​
Response Fields

​
chain_id
number
EVM chain ID echoed at the response root.

​
Meta

​
meta
object
Echo of request metadata applied to the response.
​
meta.request_window
object
Block/timestamp bounds derived from the request.
​
meta.filters
object
Filters echoed from the request (block numbers, tx hashes, contract addresses, topics).

​
Data

​
data
object[]
Array of log objects.
​
data.block_number
number
Block height containing the log.
​
data.block_hash
string
Keccak-256 hash of the block containing the log (32 bytes, hex string, no 0x prefix).
​
data.block_time
string
Block timestamp joined from the blocks table for easier aggregation.
​
data.tx_hash
string
Keccak-256 hash of the transaction emitting the log (32 bytes, hex string, no 0x prefix).
​
data.tx_index
number
Zero-based index of the parent transaction within the block.
​
data.log_index
number
Position of the log within the transaction.
​
data.contract_address
string
Address of the emitting contract (20 bytes).
​
data.topic_zero
string
Primary topic hash identifying the event (32 bytes). null for anonymous events.
​
data.data_topics
string[]
Subsequent event topics (topics[1..n]), each stored as a 32-byte hex string.
​
data.data
string
Raw event data payload (hex string (no 0x prefix)).
​
data._tracing_id
string
Tracing identifier for the canonical transaction record (hex string, no 0x prefix).
​
data._created_at
string
Record creation timestamp.
​
data._updated_at
string
Record last update timestamp.

​
Envelope Fields

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