LIVE ENDPOINT METADATA
Per-market Polymarket taker-flow concentration, price-band and book compatibility. Never a fraud verdict. BEFORE YOU PAY: free substitute https://dash.polym.uk/markets.json. THIS ADDS: One market instead of the whole snapshot, when it is decomposed. Outside that set: 422, and no charge.

Take a covered markets[].conditionId from the free snapshot at https://dash.polym.uk/markets.json, or call GET /coverage (free) for how many markets are decomposed right now. A conditionId outside the covered set returns 422 and is not billed."
