APIs

API	Description
`.price()`	Selects OHLC price columns.
`.volume()`	Selects coin or dollar volume columns.
`.trades()`	Selects buy, sell, or total trade counts.
`.for()`	Selects the exchanges and the coins or products to query.
`.over()`	Selects the time window and resolution.

Step	Property	Description
`.for()`	`exchanges`	Restricts the exchanges. Every exchange is selected when omitted.
`.for()`	`coins` / `products`	Targets Velo-aggregated coins, or exchange-native products.
`.over()`	`between` / `last`	An explicit `[begin, end)` range, or a trailing duration.
`.over()`	`resolution`	Sets the returned bucket size.

Builder queries require exactly one target (either coins or products), one time range (between or last), and a resolution.
