Poly CLOB: Raw Polymarket CLOB order book for one outcome token — every resting bid and ask exactly as the exchange returns it. Needs a token id from x402-poly-markets or x402-polymarket. For derived views use x402-poly-depth (cumulative), x402-poly-walls (large clusters) or x402-poly-signals (just the touch).

Poly Depth: Cumulative Polymarket order-book depth for one outcome token, walking outward from the touch — how much size it takes to move the price. Built from the same book as x402-poly-clob; x402-poly-walls shows the largest individual price clusters instead.

Poly Markets: The busiest Polymarket markets right now, with the full tradable record — conditionId, CLOB token ids, outcome names and prices, bid/ask, 24h volume, liquidity, end date and minimum price tick. Use x402-poly-volume to rank by activity rather than size, or x402-polymarket-odds to look up a market you already know.

Poly Signals: The touch for one Polymarket outcome token: best bid, best ask, midpoint, spread in absolute and relative terms, and whether the book is one-sided. Use x402-poly-clob when you need the full book rather than the top of it.

Poly Walls: The largest resting price clusters in a Polymarket order book — the prices where the most size is stacked, which is where a move tends to stall. minSize tunes the threshold. Siblings: x402-poly-clob (raw book), x402-poly-depth (cumulative depth).

Polymarket: Browse Polymarket markets by tag/category, with everything you need to trade what you find — conditionId, CLOB token ids, outcome names and prices (the market's implied odds), current bid/ask, end date and the minimum price tick. Use this when you know the category you want; use x402-poly-price to search by keyword, x402-poly-markets for the overall busiest markets, and x402-polymarket-scan for whole events instead of single markets.

x402-polymarket-scan: Scan live Polymarket events ranked by volume, each with its markets inside — one call shows a whole topic rather than a single question. The cheapest entry point in this family: use it to see what is worth looking at, then x402-polymarket-odds for the specific market you pick.
