Polymarket Event Markets Scraper — official public API, no login
**Polymarket API** — Live market data from Polymarket via its official public Gamma API: question, Yes/No prices, volume, liquidity, bid/ask, open/close dates. No login, no API key.Live market data from Polymarket, the largest prediction market, via its official public
Gamma API (gamma-api.polymarket.com). Polymarket's own docs describe this endpoint as the
public way to pull market data — no account, no API key, no proxies.
Tested (2026-09-02)
| Event slug | Markets returned | Time |
|---|---|---|
xi-jinping-out-before-2027 | 1 | <1s |
presidential-election-winner-2028 | 128 | <1s |
Each event returns every market nested inside it in a single response — no separate paging needed for a given event.
Polymarket API — input
Each target is an event slug — the part of the URL after polymarket.com/event/. One event
groups related markets (e.g. one candidate per market inside a presidential-election event). A
slug with no event returns 0 items for that target only (no charge).
Polymarket API — output fields
One dataset item per market:
| Field | |
|---|---|
market_id / slug / condition_id | market identifiers |
question | the market's yes/no question |
outcomes / outcome_prices | JSON-encoded arrays, e.g. ["Yes","No"] / ["0.25","0.75"] |
active / closed / restricted | market lifecycle flags |
volume_usd / volume_24h_usd | total and 24h trading volume in USD |
liquidity_usd | resting order-book liquidity |
best_bid / best_ask / last_price | current order book and last trade |
open_time / close_time | ISO 8601 lifecycle timestamps |
result | UMA resolution status once settled |
No personal data: wallet-address fields (market creator, resolver) are intentionally excluded. Output is market and pricing fields only.
Why this over Polymarket's own site
polymarket.com is built for browsing one event at a time. This actor runs a batch of event slugs in one call and hands back every nested market as structured rows — for market monitors, historical price trackers, or quant research pipelines.
Use Cases
- Market monitor dashboards — batch a list of event slugs into one structured table instead of opening each event page by hand
- Historical price/volume tracking — run on a schedule to build a time series of
best_bid/best_ask/volume_usdper market for later analysis - Quant research input — feed
outcome_pricesandvolume_usdstraight into a model without screen-scraping the site
Pricing
Pay per event: $1.00 per 1,000 markets collected. Nothing else.
