answers 402
The daily US Treasury par yield curve (Constant Maturity Treasury rates) for every maturity from 1 month to 30 years, in percent. Defaults to the latest published day; pass `?limit=` for more recent days (max 250) and `?year=YYYY`. No ticker needed. Use for the risk-free rate, rate-sensitivity context, and yield-curve inversion in macro-aware analysis. From x402stock
