Description

Returns open-high-low-close (OHLC) candles for ERC-20 base and quote token pairs. Candles are computed using BlockDB’s consolidated trade and quote data.
For fiat quotes (e.g., USD, EUR), use the dedicated /evm/prices/spot/fiat/* endpoints.

​
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_token_address
string
required
ERC-20 contract address for the quote asset (hex string, 20 bytes, no 0x prefix).

​
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.

​
Direct Selectors

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

​
Candle Controls

​
aggregation_interval
string
Candle width, expressed as an ISO-8601 duration shorthand (1m, 5m, 1h, 1d). Default is 1m.
​
aggregation_timezone
string
IANA timezone identifier used to anchor candle boundaries. Default is UTC.

​
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_token_address
string
ERC-20 contract address of the quote asset.

​
Meta

​
meta
object
Echo of request metadata applied to the response.
​
meta.request_window
object
Normalized block/timestamp bounds derived from the request.
​
meta.filters
object
Filter parameters echoed from the request.

​
Data

​
data
object[]
OHLC candles matching the request.
​
data.open
string
Opening price for the bucket.
​
data.high
string
Highest price within the bucket.
​
data.low
string
Lowest price within the bucket.
​
data.close
string
Closing price for the bucket.
​
data.volume_base
string
Aggregated executed volume in base units.
​
data.volume_quote
string
Aggregated executed volume in quote units.
​
data.start_timestamp
string
Inclusive start of the candle window (ISO-8601).
​
data.end_timestamp
string
Inclusive end of the candle window (ISO-8601).
​
data.bucket
string
Bucket anchor timestamp for the interval.
​
data._tracing_id
string
Tracing identifier for the candle.
​
data._parent_tracing_ids
string[]
Parent lineage references.
​
data._genesis_tracing_ids
string[]
Lineage references to original on-chain events.
​
data._created_at
string
Record creation timestamp.
​
data._updated_at
string
Record update timestamp.

​
Envelope Fields

​
cursor
string | null
Pagination cursor.
​
count
number
Number of candles returned.

​
Usage Notes

  • Fiat quotes adopt decimal precision specified by the fiat currency enumeration.
  • When multiple exchanges contribute to the candle, BlockDB emits consolidated OHLC values weighted by trade volume.
