What it returns

One stablecoin's USD price, one point per day at 00:00 UTC, over the last 7, 30, 90, 180 or 365 days, or since December 2020 with days=all, addressed by its id from GET /stablecoin-analysis/stablecoins. For a USD peg pegUsd is 1 and each point carries deviationPct, its distance from the peg in percent; for any other peg (EUR, GBP, a floating target…) pegUsd and deviationPct are null, since the peg itself moves against the dollar. priceUsd is null on a day without a price. Windows count back from the newest point, the current or previous UTC day. An id that is not in the directory, or a stablecoin that has never been priced, returns 404.
