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
Historical per-venue funding rates for one crypto perpetual, aggregated 1h/4h/1d, across tracked CEX and DEX venues — the timeseries a funding-arb backtest needs. Up to 30-day windows (30-day retention). Edge-isolated: raw rates only, no spread or signal logic.
