GET /treasury/rates

live

US Treasury interest rates: the Daily Treasury Par Yield Curve fused with the average interest rates on the outstanding debt by security type. Computes the 2s10s spread and an inversion flag. The yield curve is a resilient partial grain that degrades to the average rates if its upstream is unreachable.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
