PropLine
PropLine
$0 (free tier) / $19 per month
PropLine is an innovative API that provides real-time betting odds for player props across 34 different sports and 13 bookmakers, including prominent ones like Pinnacle and four exchanges (Kalshi, Polymarket, Smarkets, Matchbook), which are not available on platforms like the-odds-api and OddsJam. Distinguishing itself from others, it uniquely resolves player props based on actual box scores, delivering outcomes for every Over/Under bet—indicating whether it was won, lost, pushed, or voided, along with the actual statistical values. The pricing model charges per request rather than per credit, meaning that player prop bets and alternative lines won't inflate your expenses as they often do with credit-based APIs. Additionally, the response format is compatible with the-odds-api, making the transition to using it as simple as changing the base URL. Users can access a free tier that allows for 1,000 requests per day without requiring a credit card; for those needing more, the Pro plan is priced at $19 per month, offering 25,000 requests daily along with cross-book +EV insights, historical line movements, and graded resolutions; the Streaming plan, at $79 per month, provides a staggering 1 million requests daily alongside HMAC-signed webhooks for enhanced security. Along with these features, PropLine also offers official SDKs for Python, Node, MCP, and CLI, ensuring users have a seamless integration experience. This comprehensive approach makes PropLine a compelling choice for serious bettors looking for reliable and extensive data.
