Polymarket Events Scraper

Polymarket Events Scraper

Scrape Polymarket events by tag, status, or volume, up to a million per run. Every event comes with its markets, outcomes, prices, and liquidity. No API key required. Export to CSV, JSON, Excel, or XML.

Polymarket's prediction markets move fast, but pulling structured event data for analysis means wrangling paginated APIs or building your own scraper. This Actor reads the public Polymarket event feed directly, filtered by tag slug, active or closed status, and ordered by volume, liquidity, or date, and returns each match in one fixed schema.

Who uses it	What they scrape Polymarket for
Prediction market traders	Spot high-volume events where liquidity is concentrated before placing a bet.
Data analysts	Build a time-series dataset of event volumes and closing prices for backtesting strategies.
Crypto researchers	Track which crypto-related events are attracting the most capital this week.
News monitors	Identify breaking-news events by sudden spikes in volume on politics or world tags.

What it does

This Actor collects Polymarket events by tag, status, and sort order, and returns each one as a flat row with its markets and outcomes.

• 🏷️ Tag filtering: restrict to a single tag slug like sports, politics, or crypto.
• 📊 Volume and liquidity sorting: order events by the metrics that matter for trade sizing.
• ⏱️ Status filters: pull only active events, only closed events, or both.
• 📈 Date ordering: sort by start date or end date to see what is new or about to resolve.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with Polymarket data

📈 Monitor volume leaders.

A trader runs the Actor daily with order=volume and active=true to see which events are attracting the most capital, then sizes positions accordingly.

🔍 Research closed markets.

A data scientist sets closed=true and order=endDate to collect resolved events for a historical accuracy study of prediction market prices.

🏈 Track sports markets.

A sports analyst filters by tagSlug=sports and order=liquidity to find the deepest markets for NFL and NBA events each weekend.

🗳️ Follow political events.

A newsroom developer pulls active events with tagSlug=politics every hour to feed a live dashboard of election and policy market movements.

Troubleshooting

Why am I getting no results?

Check that your tagSlug is spelled correctly and that the active/closed filters match the events you expect. Try clearing both status checkboxes to see all events.

Why are my results missing some events?

The maxItems field caps the total returned. Increase it if you need more events, or narrow the filters to a specific tag or status to avoid hitting the limit on unrelated events.

The order I chose does not seem to be working.

Make sure the ascending checkbox is set the way you intend. The default is descending, so volume will show highest first unless you check ascending.

I got an error about the tag slug.

Tag slugs are case-sensitive and must match Polymarket's internal names exactly. Try a known slug like sports or politics first, then check the Polymarket site for the exact slug you need.

The run timed out.

Large maxItems values with broad filters can take time. Lower maxItems, add a tag filter, or increase the Actor's timeout in the run settings.

FAQ

Question	Answer
Do I need a Polymarket account or API key?	No. The Actor reads the public event listing that Polymarket serves to web visitors, so no login or key is required.
What is a tag slug?	A tag slug is the short identifier Polymarket uses for categories, like sports, politics, crypto, or science. You can find them in Polymarket URLs or by browsing the site.
Can I get both active and closed events in one run?	Yes. Leave both the active and closed checkboxes unchecked, and the Actor will return events regardless of status.
How many events can I collect per run?	You set the maximum with the maxItems field, up to 1,000,000 events per run. The Actor stops when it hits that number or runs out of matching events.
What does the order field sort by?	You can sort by volume, liquidity, endDate, or startDate. The default is volume descending, and you can flip it to ascending with the checkbox.
Does this return individual market prices?	Yes. Each event row includes its nested markets and outcomes, with prices and volumes, flattened into the output schema.
Can I filter by multiple tags at once?	The tagSlug field accepts one slug per run. To collect multiple tags, run the Actor once per tag and merge the datasets.
Is this the same data I see on polymarket.com?	Yes. The Actor reads the same public feed that powers the Polymarket website, so the data matches what you see in the browser.
How fast is a typical run?	Speed depends on the number of events requested and Polymarket's response time, but a few hundred events usually complete in under a minute.
Can I schedule this to run automatically?	Yes. Use Apify's scheduler to run the Actor every hour, day, or week, and push the results to a dataset, database, or webhook.
