​
Overview

  • Dataset ID: 0301 - Liquidity Pool Reserves
  • Description: Retrieves time-series snapshots of AMM pool reserves, covering both even-distribution (constant-product, weighted, stable) and concentrated/bin liquidity models.
  • CSV Sample: Download
  • JSON Sample: Download
For concentrated liquidity (Uniswap v3/v4-style) tick distribution, use the dedicated POST /v1/evm/reserves/liquidity-distribution endpoint, which computes per-tick amounts on demand with a configurable price window.

​
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 at least one direct selector.
Providing more than one option results in HTTP 400.
Providing none results in HTTP 400.

​
Pool Selectors

​
exchange_ids
number[]
Filter snapshots by exchange IDs. See the DigitalExchange enumeration for supported values.
​
pool_uids
string[]
Filter by BlockDB pool identifiers (uid from /evm/entities/pools).
​
pool_addresses
string[]
Filter by pool contract addresses (hex string, 20 bytes, no 0x prefix).
​
pool_ids
string[]
Filter by protocol-specific pool identifiers (e.g., Uniswap V4 pool_id).
​
pool_type_ids
number[]
Filter snapshots by pool archetype. See the PoolType enumeration for supported values.

​
Amounts

​
include_adjusted_amounts
boolean
default:"false"
Off by default. When set to true, each snapshot includes reserves_decimals_adjusted — the same reserve amounts scaled by ERC-20 token decimals (e.g. dividing a USDC value by 10⁶). Enabling it adds a per-request ERC-20 decimals lookup (extra join) that increases latency, so it is opt-in; when omitted or false, reserves_decimals_adjusted is null and only the always-present raw reserves array is populated.

​
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
Filters echoed from the request (e.g., exchange IDs, pool identifiers, pool types).

​
Data

​
data
object[]
Array of reserve snapshot objects.
​
data.pool_uid
string
BlockDB pool identifier (uid from /evm/entities/pools).
​
data.exchange_id
number
Exchange identifier associated with the pool.
​
data.type_id
number
Pool type identifier.
​
data.block_number
number
Block height where the reserve change was observed.
​
data.block_time
string
Block timestamp when the event occurred.
​
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.reserves
string[] | null
Current reserves per token in pool order, as raw integer strings (base units). null for concentrated-liquidity pools where reserves are not stored at the snapshot level.
​
data.reserves_decimals_adjusted
string[] | null
Same order as reserves, but each value divided by 10^decimals for the corresponding ERC-20 token. null when decimals are unavailable for at least one pool token, when reserves is null, or when include_adjusted_amounts is false.
​
data.current_tick
number | null
Current tick for concentrated-liquidity pools. null when not applicable.
​
data.current_sqrt_price
string | null
Q64.96 sqrt price as an integer string. null when not applicable.
​
data.current_bin
number | null
Current bin id for bin-style AMMs. null when not applicable.
​
data._tracing_id
string
Row-level lineage hash for the snapshot.
​
data._parent_tracing_ids
string[]
Lineage references of immediate parents.
​
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.
