Common Questions
What do I get with a free account?
A free Oddpool account gives you 750+ event dashboards with cross-venue odds, paper trading, the prediction market search engine, historical charts, and 1 API key with 1,000 requests/month. Free accounts also get 1 WebSocket connection with access to distribution channels. No credit card required.
What's the difference between Pro and Premium?
Pro ($30/month) gives you the full dashboard suite -- arbitrage scanner, price spreads, volume rankings, whale tracking -- plus 1M API requests/month and 3 WebSocket connections. Premium ($100/month) opens up every API endpoint with 5M requests/month, 10 WebSocket connections, and unlimited event subscriptions. Built for automated strategies.
Is $30/month worth it?
Pro users find hundreds of arbitrage opportunities every week. A single arb trade can return more than the cost of a monthly subscription. If you actively trade on Kalshi or Polymarket, the scanner pays for itself quickly.
What can I build with Premium?
A bot that detects cross-venue arbs and alerts you before they close. A Telegram notification when a spread widens past 3¢. A new-market scanner that catches listings before most traders notice them. Stream real-time orderbook data over WebSocket. The API returns the same data that powers our dashboards.
Can I cancel anytime?
Yes. All plans can be cancelled from your account page at any time. You keep access through the end of your billing period.
