Description

Retrieves pool TVL (Total Value Locked) snapshots in USD. Each snapshot represents the pool’s total value computed from reserves multiplied by fiat prices at a specific on-chain event. Use this endpoint to:
  • Build TVL rankings and dashboards
  • Track liquidity migration across pools and protocols
  • Filter pools by minimum TVL for routing decisions
  • Monitor protocol health and liquidity trends

​
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 pools 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_type_ids
number[]
Filter by AMM archetype. See the PoolType enumeration for supported values.

​
TVL Filters

​
min_tvl_usd
number
Minimum TVL threshold in USD.
​
max_tvl_usd
number
Maximum TVL threshold in USD.

​
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.

​
