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
Live state of every perpetual-futures market in one call: per coin the mark and oracle price, hourly funding rate with annualized APR, premium, open interest, max leverage, previous-day price, and 24h USD and base volume. Native crypto-derivatives data — funding and open interest are perp-only, absent from any spot feed. Free on-chain DEX data (venue: Hyperliquid), no key. From x402stock
