Methodology · exchange-median-v1
The price
Each second is one USD price: the median of exchange prices that second (exchange-median-v1). A second without enough agreement is omitted, and no earlier price is filled in. Venue names and filter settings are not included in the response.
Settlement
A window without enough recorded seconds returns no price.
Version
Every response names the methodology version. That name changes when the methodology changes.
