USDJPY is the major pair for US Dollar against Japanese Yen.
About US Dollar / Japanese Yen (USDJPY)
USDJPY is the exchange rate of the US dollar against the Japanese yen, quoted as the number of yen for one dollar. It is one of the most actively traded pairs and, unlike the euro or pound pairs, it is quoted with the dollar as the base currency.
SiftingIO consolidates USDJPY across independent sources into a single rate. The live quote returns bid and ask with sizes, the mid, a spread in basis points, the contributing venue count, the 24-hour change, and a millisecond timestamp. It is available over REST as a snapshot and over WebSocket as a stream.
Historical bars run over REST from one-minute to daily resolution, timestamped in UTC. Note that FX bars report a volume of zero, because there is no central exchange tape for spot currencies, while open, high, low, and close are fully populated. Reachable history is governed by your plan tier, from a recent slice on the free tier to the complete series higher up, as listed on the pricing page.
The update rate scales with tier from one to ten per second, and the median publish age is under 100 milliseconds, a data-freshness figure and not an execution latency. Each rate is a robust, venue and reputation weighted median stamped with source, ingest, and publish times and a quality flag.
