PropLine Description
PropLine is an API that provides real-time betting odds for player props across 54 sports and 25 books, including prominent ones like Pinnacle and six exchanges (Kalshi, Polymarket, Smarkets, Matchbook, Novig, ProphetX), 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. The Hobby plan, at $9 per month, covers 5,000 requests daily and unlocks every paid feature: cross-book +EV with no-vig fair lines, historical line movement, opening and closing lines for CLV tracking, and graded prop resolution. The Pro plan, at $19 per month, raises that to 25,000 requests daily and adds bulk CSV exports. Streaming Lite at $39 per month provides 100,000 requests daily and Streaming at $79 per month provides 1 million, both with HMAC-signed webhooks that push line movements and settled results as they happen. PropLine also offers official SDKs for Python, Node, MCP, and CLI, ensuring users have a seamless integration experience.

Excellent quality and excellent value Edited: Aug 24 2026
Summary: I could not be happier with the provider, looking to add more of their data to my system and try out all the features.
Positive: Great collection of bookmakers (not just 20 copies 1xbet clones) , combining breadth and sharpness. Huge amount of features. Historical data available too, but I have not tried.
Negative: I mean frankly, none. Any system like that occasionally has issues, and when I found something and emailed support the issue was fixed really fast, once literally within minutes.

The most reliable, consistent and cost efficient API on the market. Date: Aug 24 2026
Summary: I have tried many APIs for my site and they were either crazy expensive or just flat out unreliable. PropLine solved both of those issues immediately they are very well priced which usually means the quality and reliability suffer greatly, but that's not the case here. 10/10 product 10/10 service!
Positive: - Reliable
- Easy to use
- Plenty of data
- Never run out of API calls especially with well priced webhooks
- Most cost efficient product on the market and it's not even closeNegative: Really can't think of much, maybe there could be a few more books but I know that is something Andy is consistently working on and I have no doubt those will come in the near future.

Prop-Line has the most reliable API in the industry! Date: Jul 06 2026
Summary: I'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.Negative: No 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 2026
Summary: I’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.
Positive: PropLine 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.
Negative: I 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.
