Historical and real-time OHLCV time series.

Documentation GitHub OpenAPI

Operations 2

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /time_series Get historical OHLCV bars for an instrument · Time series (OHLCV) #

Ask an LLM

“How do I pull daily open, high, low, close and volume history for a ticker?”

“Can I get intraday price bars at a 5-minute interval?”

Tell an agent

Get {interval} OHLCV bars for {symbol}.

Fetch the last {outputsize} {interval} candles for {symbol}.

GET /time_series/cross Compute a cross-rate series between two instruments · Cross time series #

Ask an LLM

“Can I get a price history for an exotic currency pair that is not quoted directly?”

“What would a cross rate between two instruments look like over time?”

Tell an agent

Compute the {interval} cross-rate series for {symbol}.

Build a synthetic cross time series for {symbol} at {interval}.
