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
This-session snapshot only — no watch, no cursor. Use when you will not come back. Required by type: url/rss/x402 need url; price needs coin plus above, below, or move_pct_24h; edgar needs ticker or cik. 8-K items are decoded, Form 4 trades parsed, and x402 probes validate the unpaid 402 challenge without sending payment. If the job spans runs, create_watch instead and persist watch_id + key.
