Series

Every US inflation measure with all four windows worked out

Headline and core CPI and PCE, supercore, the trimmed means, the median, the sticky and flexible splits, the CPI components, and what markets expect next. Each measure returns its year-over-year reading plus 1, 3 and 6-month annualised, so no caller has to annualise anything itself. Also reports which parts of the basket are driving the headline rate over the last year. The latest reading answers on every tier, including keyless, because it is a single published figure. For the first 60 minutes after a print that feeds this board, Sample and Free get the board without it, and held_until says when it joins. The monthly HISTORY behind it follows your plan's window (7 days on a free key, 12 months Starter, 24 months Pro, 10 years Ultimate); a call that hits the window still returns the newest month and adds a plan_limit block naming the month it reached back to.
