Description

Returns volume-weighted average prices (VWAP) for ERC-20 base tokens quoted in fiat currencies. This endpoint mirrors the ERC-20 pairing, letting you benchmark execution quality without running a separate FX stack.
Provide quote_currency_code using values from the Fiat Currency enumeration.

​
Parameters

​
chain_id
number
required
Target EVM chain. See the Chain enumeration for supported values.
​
base_token_address
string
required
ERC-20 contract address for the base asset (hex string, 20 bytes, no 0x prefix).
​
quote_currency_code
string
required
Fiat currency code for the quote leg.

​
Range Filters (mutually exclusive)

​
from_block
number
Starting block number (inclusive) for the query window.
​
to_block
number
Ending block number (inclusive) for the query window.
​
from_timestamp
string
Starting timestamp (ISO-8601). If it falls between blocks, the next block after this timestamp is used.
​
to_timestamp
string
Ending timestamp (ISO-8601). If it falls between blocks, the last block before this timestamp is used.
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.

​
Direct Selectors

​
exchange_ids
number[]
Filter by exchange identifiers. See the DigitalExchange enumeration.
​
pool_uids
string[]
Restrict to specific BlockDB pool identifiers.

​
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.
​
base_token_address
string
ERC-20 contract address of the base asset.
​
quote_currency_code
string
Fiat currency code for the quote leg.

​
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 applied to the query (exchange IDs, pool UIDs).

​
Data

​
data
object[]
VWAP aggregates matching the request.
​
data.chain_id
number
EVM chain identifier.
​
data.pool_uid
string

Number of trades contributing to the VWAP.
​
data.volume_base
string

Ending block number for the window.
​
data.start_timestamp
string
Inclusive start of the window (ISO-8601).
​
data.end_timestamp
string
Inclusive end of the window (ISO-8601).
​
data._tracing_id
string
Tracing identifier for the VWAP row.
​
data._parent_tracing_ids
string[]
Parent lineage references.
​
data._genesis_tracing_ids
string[]
Lineage references to original on-chain events.
​

string
Record creation timestamp.
​
data._updated_at
string
Record update timestamp.

​
Envelope Fields

cursor
string | null
Pagination cursor.
​
count
number
