What is PropLine?
PropLine is a cutting-edge API that delivers real-time betting odds for player props across 34 sports and 13 bookmakers, including major names such as Pinnacle and four exchanges like Kalshi, Polymarket, Smarkets, and Matchbook, which are not found in services like the-odds-api or OddsJam. What sets it apart is its unique ability to resolve player props based on actual box scores, providing detailed results for every Over/Under bet—indicating whether the bet was a win, loss, push, or void, along with the precise statistical figures. The pricing structure is designed to charge per request instead of per credit, meaning that costs for player prop bets and alternative lines will not soar as they typically do with credit-based APIs. Additionally, the response format aligns with that of the-odds-api, allowing for an effortless transition by simply changing the base URL. Users can take advantage of a free tier that permits up to 1,000 requests daily without needing a credit card; for those who require more, the Pro plan is available for $19 per month, providing 25,000 daily requests, along with cross-book +EV insights, historical line movements, and graded resolutions, while the Streaming plan at $79 per month offers a remarkable 1 million requests daily and HMAC-signed webhooks for enhanced security. PropLine's impressive features are complemented by official SDKs for Python, Node, MCP, and CLI, ensuring a smooth integration experience for users. This thorough and user-friendly approach positions PropLine as an excellent option for serious bettors seeking reliable and comprehensive data to enhance their betting strategies. Furthermore, its innovative features and flexible pricing make it an attractive choice for both new and experienced bettors alike.

Prop-Line has the most reliable API in the industry!
Date: Jul 06 2026SummaryI'm ecstatic with the services that Prop-Line offers. The API they offer has everything a user would need. Prop-Line can support casual/novice users all the way to Professional gamblers and Developers in this industry.
Positive-Reliability is top notch quality
-Accuracy is phenomenal
-Data speeds are excellent
- Support is available 24/7. They respond almost immediately if there is an issue.NegativeNo cons found. I have been using on a daily basis since April 2026 and have zero complaints. If I had to "find" a con to list, it would be building out Prop-Line with the intent of Live Betting. During Live betting, Odds & Lines change frequently so it's a complete different beast.

Excellent API, Outstanding Support
Date: Jul 04 2026SummaryI’ve been using PropLine daily while building a sports analytics application, and it’s been a great experience. The API is reliable, the documentation is clear, and the support has been exceptional. It’s rare to find a team that responds this quickly and genuinely values customer feedback. I highly recommend PropLine to anyone building sports betting, analytics, or odds applications.
PositivePropLine has been one of the best APIs I’ve worked with. The API is fast, well documented, and easy to integrate, with excellent coverage across sports and player props. What really stands out is the support. The team listens to feedback, responds quickly, and has shipped multiple improvements based on real developer suggestions. The pricing is also very fair compared to other sports data providers.
NegativeI honestly don’t have any major complaints. I’d love to see the platform continue expanding with even more sports, markets, and documentation over time, but the team has been consistently improving the product and adding new features.
