polymarket_event_books

Pack: polymarket · Endpoint: https://gateway.pipeworx.io/polymarket/mcp

Batched CLOB orderbooks for EVERY tradable market in one Polymarket event — single round trip via the CLOB batch /books endpoint. Use before any multi-leg strategy (partition arbitrage “SELL/BUY EVERY LEG”, basket trades) to check per-leg depth: theoretical overround means nothing if half the legs are 50-share books. Returns legs[] with {slug, question, yes_price, best_bid, best_ask, yes_bids[], yes_asks[]} where bids are sorted best(highest)-first and asks best(lowest)-first as {price, size} objects. Pass include_no=true to also fetch NO-side books (doubles payload — only needed for NO-leg strategies). Caps at 80 legs (highest yes_price kept; truncated_legs reports the cut).
