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
Latest euro area risk-free spot yields from the ECB Data Portal (dataset YC, AAA-rated central government bonds, Svensson model; updated each business day ~12:00 CET). Query: ?tenors=3M,1Y,2Y,5Y,10Y,30Y (1-8 tenors from 3M to 30Y). Returns yields_pct per tenor, observation date, and the 2s10s spread in bp when 2Y and 10Y are requested. 1h cache.
