- Auth: none declared

The live TRADEABLE prediction-market surface, normalised for polling bots. Every liquid Polymarket market above a 24h-volume floor, each with its Yes probability, `edge` (min(yes,1-yes) — 0=resolved, 0.5=coin-flip), 24h volume, and liquidity. Query: min_volume (USD floor, default 1000), uncertain_only (true drops near-resolved), sort (volume|edge|liquidity), limit (1-100). Prices move — poll it; a cached copy is stale. Built for continuous trading loops, not one-shot lookups.

Paid endpoint: $0.020 per call via the x402 protocol (USDC on Base). An unpaid request returns 402 with payment requirements in the PAYMENT-REQUIRED response header; attach payment and retry.

- `min_volume` string
- `sort` string
- `limit` string

Paid result (JSON)

## Other responses
