Get latest aggregated CEX prices

get

/cex/latest

operationId: cex-latest

Returns the most recent aggregated price for each (asset, base) pair, computed across all active CEX exchanges using multiple algorithms (PMAP, VWAP, FMAP, SDAP, MMMAP). Optional filters narrow to a specific asset or base; sort/direction reorder the deduplicated set.

Successful response

Field	Type	Description
`items`	object[]	Latest aggregated prices, one row per (asset, base) pair.
`items[].asset`	string	Asset symbol (e.g. `XRP`).
`items[].base`	string	Base currency (e.g. `USDT`).
`items[].timestamp`	integer	Aggregation timestamp, Unix-seconds.
`items[].pmap`	object	Pure Mean Average Price (decimal string).
`items[].vwap`	object	Volume-Weighted Average Price (decimal string).
`items[].fmap`	object	Fixed Mean Average Price (decimal string).
`items[].sdap`	object	Standard Deviation Average Price (decimal string).
`items[].mmmap`	object	Middle Median Mean Average Price (decimal string).
`items[].cwap`	object	Confidence-Weighted Average Price (decimal string). Same shape as FMAP but applies the per-exchange confidence score from the static `exchange-weights.ts` registry as `weight²` so high-confidence venues dominate by a square factor. NULL on rows produced before the algorithm was added (pre-migration `0009`).
`items[].standardDeviation`	object	Standard deviation across exchanges (decimal string).
`items[].exchangeCount`	object	Number of exchanges contributing to the aggregate.
`items[].totalVolume`	object	Total trade volume backing the aggregate (decimal string).
