fred — the SS7 walk
Macroeconomic context from the St. Louis Fed — 21.7 million observations across 845,501 series, with the whole catalog in scope rather than a convenient handful. FRED revises history as a matter of course; the walk's job is making sure a revision can never impersonate the original reading.
