How this service works

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

Output

Returns US Treasury yield data across maturities (e.g. 1-month, 3-month, 6-month, 1-year, 2-year, 5-year, 7-year, 10-year, 20-year, 30-year), including current rates and potentially historical time series, enabling yield curve analysis and macro research.

Example use cases

Yield curve inversion monitoring

“Check the current US Treasury yields and tell me if the yield curve is inverted — specifically compare the 2-year and 10-year rates.”

Risk-free rate for DCF model

“What's the current 10-year US Treasury yield? I need it as the risk-free rate for my discounted cash flow valuation.”

Macro rate environment briefing

“Give me a snapshot of today's Treasury yields across the major maturities — 3-month, 2-year, 5-year, 10-year, and 30-year — so I can assess the current rate environment.”
