How this service works
Browse Polymarket events (an event groups related markets — e.g. an election, a tournament, a price ladder). Optional keyword q, closed filter, order (volume/volume24hr/liquidity), and limit/offset. Each event returns its title, tags, USD volume + 24h volume, liquidity, dates, and the nested markets with their outcomes + live outcome prices (implied probabilities) and CLOB token ids. Read-only mirror of Polymarket's Gamma events.
Output
Returns a list of Polymarket events, each with title, tags, total USD volume, 24h volume, liquidity, start and end dates, and nested markets containing their outcomes, live outcome prices (implied probabilities), and CLOB token ids for trading.
Example use cases
Example prompt
“Pull up the top 20 Polymarket events about the 2024 US election sorted by 24-hour volume, and show me the live implied probabilities for each outcome.”
