GET /market-authenticity/:conditionId

unprobed

Per-market Polymarket taker-flow concentration, price-band structure and book compatibility. Facts, never a fraud verdict. BEFORE YOU PAY: free substitute https://dash.polym.uk/markets.json. THIS ADDS: A single-market lookup instead of the whole snapshot, for a decomposed market. Outside that set: 422, and no charge.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
