About Bitcoin / US Dollar (BTCUSD)
BTCUSD is the price of one bitcoin in US dollars. Bitcoin trades around the clock across many independent venues, and because those venues can disagree at any instant, a single consolidated number is more useful for analytics than any one order book.
SiftingIO returns exactly that: one fair BTCUSD price aggregated across multiple centralized venues. The live quote carries price, bid, ask, a spread in basis points, 24-hour volume and change, the count of contributing venues, and a timestamp. It is reachable as a REST snapshot or as a WebSocket subscription for a continuous stream.
Historical open, high, low, close, and volume bars are available over REST at one-minute, five-minute, fifteen-minute, and hourly resolution, with coarser intervals on the product side, and the bar volume is the base-asset amount, here bitcoin. How far back the bars go is set by your plan tier, from a recent window on the free tier to the full archive higher up, as listed on the pricing page.
The live update rate climbs with tier from one to ten per second, and the median publish age stays under 100 milliseconds as a freshness measure. Every price is a volume and reputation weighted median, stamped with source, ingest, and publish times and a quality flag, so you can see how each number was formed.
