​
Overview

​
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 block_hashes.
​
block_hashes
string[]
Explicit set of block hashes (hex string, 32 bytes, no 0x prefix). Mutually exclusive with block_numbers.

​
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

​
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
Filters echoed from the request (contract addresses, block numbers, limit).

​
Data

​
data
object[]
Array of block objects.
​
data.block_number
number
Sequential block height.
​
data.block_hash
string
Keccak-256 hash of the block header (32 bytes, hex string, no 0x prefix).
​
data.parent_block_hash
string
Keccak-256 hash of the parent block (32 bytes, hex string, no 0x prefix).
​
data.receipt_root
string
Merkle root of transaction receipts (32 bytes).
​
data.miner
string
Fee recipient / coinbase address (20 bytes).
​
data.gas_limit
number
Block gas limit.
​
data.extra_data
string
Extra data payload supplied by the miner (<= 32 bytes, hex-encoded).
​
data.size
number
Block size in bytes.
​
data.timestamp_utc
string
Timestamp when the block was mined.
​
data._tracing_id
string
Tracing identifier for the canonical block record (hex string, no 0x prefix).
​
data._computed_receipt_root
string
Recomputed receipts root for BlockDB integrity checks.
​
data._computed_receipt_timestamp_utc
string
Timestamp when the receipts root was (re)computed.
​
data._created_at
string
Record creation timestamp.
​
data._updated_at
string
Record last update timestamp.

​
Envelope Fields

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