​
Description

Retrieves time-series snapshots of AMM pool reserves, covering both even-distribution (constant-product, weighted, stable) and concentrated/bin liquidity models.

​
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/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.

​
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

​
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 (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/pools).
​
data.exchange_id
number
Exchange identifier associated with the pool.
​
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[]
Raw token reserves for even-liquidity pools (one entry per token, no decimals applied).
​
data.current_tick
number
Active tick for concentrated-liquidity pools (Uniswap v3/v4-style).
​
data.current_sqrt_price
string
Q64.96 sqrt price as an integer. Convert via sqrt_price / 2^96 to get sqrt(P); square and adjust for decimals to derive mid-price.
​
data.current_bin
number
Active bin for bin-based AMMs (e.g., TraderJoe v2).
​
data.details
object[]
Present when include_details = true. Each object conveys liquidity concentrated around a tick/bin/range.
​
data.details[].tick
number
Single tick locator for v3-style records.
​
data.details[].lower_tick
number
Lower bound of a tick range summary.
​
data.details[].upper_tick
number
Upper bound of a tick range summary.
​
data.details[].bin_id
number
Bin locator for bin-based pools.
​
data.details[].liquidity
string
Engine-native liquidity metric (e.g., Uniswap v3 L).
​
data.details[].amount0
string
Token0 amount at the locator (decimals-adjusted).
​
data.details[].amount1
string
Token1 amount at the locator (decimals-adjusted).
​
data._tracing_id
string
Row-level lineage hash for the snapshot.
​
data._parent_tracing_ids
string[]
Lineage references of immediate parents.
​
data._genesis_tracing_ids
string[]
Lineage references to original on-chain events.
​
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.
