GET /api/v1/gdp

unprobed

US real Gross Domestic Product, quarterly, in billions of chained 2017 dollars (seasonally adjusted annual rate), with the latest reading, prior quarter, quarter-over-quarter and year-over-year change, and recent history. No ticker needed. The broad measure of economic output for macro-aware analysis. Sourced from the St. Louis Fed (FRED). From x402stock

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
