`polymarket_event`

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

Get a Polymarket event with EVERY child market at once. Events group mutually-exclusive outcomes (e.g., “2028 Democratic nominee” has one Yes/No market per candidate, each price = implied probability of that candidate). Use when you need the full slate — election candidates, championship contenders, multi-option outcomes — instead of one specific market. Returns event metadata + array of child markets with live prices, volumes, end dates.

Parameters

Name	Type	Required	Description
`slug_or_id`	string	yes	Event slug (e.g. “2028-presidential-election”) or numeric id
