Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
The average interest rate the US Treasury currently pays on its outstanding debt, broken out by security (Treasury Bills, Notes, Bonds, TIPS, FRNs, savings, and the marketable/total aggregates) for the latest reported month, in percent. No ticker needed. A read on the government's cost of borrowing that complements the /treasury-yields curve. Sourced from the US Treasury (FiscalData).
