Get OHLC candles for a symbol. Returns open/high/low/close buckets for an asset over a configurable lookback window, sampled at a configurable resolution. Use for candlestick charts and volatility measures that need the intra-bucket range rather than a single close. Only sources that store individual ticks can produce OHLC. Requesting candles for an asset priced from a derived or snapshot source returns `400`. See the [Time Window & Resolution](#section/Time-Window-and-Resolution) section for the format of `window` and `resolution`.
Get reported market-cap history. Returns an asset's reported market capitalisation in USD over a configurable lookback window, sampled at a configurable resolution. Each point is the figure the data provider reported at that timestamp. The snapshot is written on the provider's ingest cadence, which is coarser than a minute, so a `resolution` of at least `1h` is what the series can actually fill. Buckets with no snapshot behind them are absent rather than zero. See the [Time Window & Resolution](#section/Time-Window-and-Resolution) section for the format of `window` and `resolution`.
Get perp funding rate and open interest history. Returns a perpetual future's funding rate and open interest over a configurable lookback window, sampled at a configurable resolution. Both series come from the same venue snapshot row, so a caller reading them together never compares values sampled at different times. `funding_rate` is the venue's hourly rate as a decimal fraction, so `0.0000125` is 0.00125% per hour. `open_interest` is a coin count of the base asset (`35984.2` for BTC), not a USD notional. See the [Time Window & Resolution](#section/Time-Window-and-Resolution) section for t…
Get price at a point in time. Returns the last known price for an asset at or before the given timestamp. Use this to value a position, settle a trade, or anchor a calculation to a specific moment in time.
Get a technical indicator series. Returns one or more technical indicator lines computed from the asset's close prices. The requested `window` is widened internally by the indicator's warm-up depth and trimmed back before responding, so the first returned point is already converged rather than carrying seed bias. The window is measured back from the most recent available point, so a feed lagging behind the current time still returns a full window. `lines` is keyed by line name. Single-line indicators (`sma`, `ema`, `rsi`, `atr`) return one entry named after the indicator. `macd` returns `ma…
Get min/max price over a window. Returns the minimum and maximum price observed for an asset within a configurable lookback window, along with the timestamps at which each extreme occurred. Useful for surfacing 24h highs/lows or computing period-over-period statistics. See the [Time Window & Resolution](#section/Time-Window-and-Resolution) section for the format of `window`.
Get reported 24h volume history. Returns an asset's reported 24h volume in USD over a configurable lookback window, sampled at a configurable resolution. Each point is the rolling 24h figure the data provider reported at that timestamp, not the volume traded inside the bucket. Two adjacent points therefore overlap by almost a full day. See the [Time Window & Resolution](#section/Time-Window-and-Resolution) section for the format of `window` and `resolution`.
