Market History (own archive)

Historical time series that no upstream provider sells. They sell the current value; we archive every value we buy, so the series over days and weeks becomes ours alone - it cannot be copied because a competitor lacks the past. Products: gas (Base gas price, Gwei), yield, commodities, market_brief. The scoring rule and point count are disclosed in every response. At least two usable points must remain after raw or daily resolution; an empty, one-point or incompletely readable archive returns an uncharged error and is never sold as a time series.
