How this service works

Fetches details for a single Polymarket event by slug or numeric ID, including all associated markets, outcome tokens, implied probability prices, volume, liquidity, resolution source, rules, and start/end dates. Information only, not financial advice.

Output

Returns a JSON object with the event's title, URL, slug, active/closed status, total volume, end date, and an array of markets. Each market includes its question, resolution rules, outcome prices (Yes/No probabilities between 0 and 1), liquidity, condition ID, and token IDs for trading on Polymarket.

Example use cases

Check political prediction market odds

“What are the current Yes/No prices on Polymarket for whether AOC will run for Senate or President before 2028? Use the slug 'will-aoc-announce-a-run-for-senate-or-president-before-2028'.”

Monitor active event and market status

“Is the Polymarket event about AOC's 2028 candidacy still active and open? Grab the details using slug 'will-aoc-announce-a-run-for-senate-or-president-before-2028' and tell me the end date and current market status.”

Research event resolution rules

“I need the full resolution rules for the Polymarket event with slug 'will-aoc-announce-a-run-for-senate-or-president-before-2028' — specifically what counts as a qualifying announcement for each market.”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/pm/event?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured Polymarket event data including all sub-markets, outcome prices, liquidity, and resolution rules for a known event slug or ID. Prefer this over scraping polymarket.com directly when you need machine-readable JSON with token IDs and condition IDs for downstream trading or analysis workflows.

Side effects

Missing or invalid slug returns an error — slug is required
Non-existent slug returns no data or 404-equivalent
Truncated or malformed response if the event has an unusually large number of markets
Stale data if Polymarket Gamma API is delayed or unavailable
Payment failure if USDC balance is insufficient for the $0.003 per-call fee
