2026.08.26 - Add Market Cap For OHLCV endpoints

A new OHLCV chart type option is now available for token OHLCV endpoints, allowing callers to return market cap candles instead of price candles without changing the response schema.

OHLCV - Market Cap Chart Type

GET /defi/v3/ohlcv
GET /defi/ohlcv

Features

Add chart_type support for token OHLCV endpoints
Support chart_type=price and chart_type=mcap
Keep price as the default for backward compatibility
Return market cap OHLC values when chart_type=mcap

Parameters

Parameter	Type	Required	Default	Description
`x-chain`	string	No	solana	Chain header. Market cap charting applies to Solana token OHLCV only.
`address`	string	Yes	-	Token address to query.
`type`	string	Yes	-	Candle interval.
`currency`	string	No	usd	Quote currency. Supports `usd` and `native` for token OHLCV.
`ui_amount_mode`	string	No	raw	Display mode for OHLCV output: `raw`, `scaled`, or `both`.
`mode`	string	No	range	Query mode: `range` or `count`.
`count_limit`	integer	No	5000	Maximum candles returned when `mode=count`. Range: `1..5000`.
`chart_type`	string	No	price	OHLC chart type: `price` or `mcap`.

Response

The response keeps the existing OHLCV structure and can return:

o, h, l, c - OHLC values as either price candles or market cap candles depending on chart_type
v - token volume, unchanged
v_usd / vUsd - USD volume, unchanged
scaledO, scaledH, scaledL, scaledC - present according to ui_amount_mode; for chart_type=mcap, these mirror market cap OHLC values
scaledV - unchanged and still follows existing scaled volume behavior
address - token address
type - candle interval
currency - requested quote currency
unix_time / unixTime - candle timestamp

Use cases

Chart token market cap history with the same OHLCV integration already used for price charts
Switch between price candles and market cap candles without changing downstream parsing
Analyze market cap structure over time for meme coins, new listings, and volatile tokens
Build charting or analytics features that need backward-compatible OHLCV responses with alternative candle semantics
