LIVE ENDPOINT METADATA

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

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
