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
Use to see where prediction-market money is flowing: the most recently traded Polymarket outcome tokens with implied probability (last on-chain price), today's VWAP and USD volume, and indexed totals — decoded by our own indexer from CTF Exchange V2 events on the public Polygon ledger, not from any Polymarket API. `?limit=` up to 100. From x402stock, a market & economic data API (x402, USDC).
