About Polymarket

Polymarket is a prediction market where users trade on the outcomes of real-world events. Its public market pages expose event questions, outcome prices, volume, and resolution details worth scraping for probability and sentiment data.

Scraping note: Market data is JavaScript-rendered and also available through public data APIs, so live prices need rendering or the API rather than the raw page HTML.

Example Polymarket page

https://polymarket.com/event/EXAMPLE-MARKET-SLUG

Pass a URL like this as url= to the Universal Web Scraper API and get it back as JSON.

Fields you can extract from Polymarket

check_small market question check_small outcome prices check_small implied probability check_small total volume check_small liquidity check_small resolution date

Common use: Track Polymarket outcome prices as crowd-sourced probabilities to feed an event-forecasting or research model.

Everything you need to scrape Polymarket

You never expose your own IP, you get validated JSON instead of raw HTML, and the free tier covers polymarket scraper at 1,000 requests a month with no card required.

data_object

Polymarket Scraper API FAQ

Is it legal to scrape Polymarket?

expand_more
Scraping publicly accessible Polymarket data is generally legal in the US under the Ninth Circuit's hiQ v. LinkedIn ruling, which held that scraping public web data does not violate the Computer Fraud and Abuse Act. It does not override Polymarket's own Terms of Service, which are a contract matter, so check those for your use case and comply with data laws such as GDPR. This is general information, not legal advice.

How do I scrape Polymarket without getting blocked?

expand_more
You scrape Polymarket without getting blocked by sending the URL to the Universal Web Scraper API, which fetches it through rotating residential proxies and retries on soft blocks. Your own IP is never used, so Polymarket's anti-bot layer sees ordinary residential traffic instead of a server.

What data does the Polymarket Scraper API return?

expand_more
Through the Universal Web Scraper API you get the Polymarket page back as JSON: rendered HTML, plain text, or auto-parsed content depending on the parse mode you pass. You choose the URL, Chocodata returns the data.

How much does the Polymarket Scraper API cost?

expand_more
The Polymarket Scraper API costs nothing to start: the Free plan includes 1,000 requests per month (5,000 credits) across all 235 targets. After that, monthly plans begin at $19, or you top up pay-as-you-go at $0.90 per 1,000 successful requests. One request is 5 credits, and non-2xx responses are never charged.

Do I need a Polymarket account or login?

expand_more
No Polymarket login is needed for public pages. You point the Universal Web Scraper API at a publicly accessible Polymarket URL with your Chocodata API key; you do not hand over any Polymarket credentials. Login-gated content is not supported.
