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
Currency exchange rate for converting between any two currencies (forex/FX rate), drawn from a set of 30+ major currencies, sourced from the European Central Bank's official daily reference rates. Updates once per business day (~16:00 CET) — not a live or intraday feed.
