How much does Polymarket Scraper cost?

$3 per 1,000, charged only for markets returned; a run that finds nothing costs nothing. It runs on Apify, whose free plan includes monthly credit, so you can try it without paying.

Do I need to write code?

No. Fill in the form on Apify and press Start, schedule it, or send the results to Google Sheets, Slack or a webhook. For code, the input builder on this page writes the API call in curl, Python or JavaScript.

What does Polymarket Scraper return?

Every row has the same fields, including marketId, conditionId, slug, eventId, eventTitle, question, outcome, url, probability, outcomes, lastPrice, yesBid, yesAsk, noBid, noAsk, spread, change24h, change7d, volume, volume24h, liquidity, category, openTime, closeTime, status (open, closed, resolved), resolutionStatus, result, rules. Download as JSON, CSV, Excel or XML.

Can it run on a schedule and return only new results?

Yes. Schedule it on Apify (hourly, daily, weekly) and turn on the only-new option: each run then returns only what appeared since the last run with the same input.
