What is PropLine?
PropLine is a cutting-edge API that delivers 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) that competing platforms such as the-odds-api and OddsJam do not carry. What sets it apart is automatic prop resolution: every Over/Under outcome is graded against the actual box score after the game and returned as won, lost, pushed, or voided, together with the real statistical value the line settled on. Billing is per request rather than per credit, so player props and alternate lines do not multiply your costs the way they do on credit-metered APIs, where each market requested is charged separately. The response schema is compatible with the-odds-api, which makes migrating a base-URL change rather than a rewrite. A free tier provides 1,000 requests per day with no credit card required. The Hobby plan, at $9 per month, provides 5,000 requests daily and unlocks the complete paid feature set: cross-book +EV with no-vig fair lines, historical line movement, opening and closing lines for closing-line value tracking, and graded prop resolution. The Pro plan, at $19 per month, provides 25,000 requests daily and adds bulk CSV exports of the graded archive. Streaming Lite at $39 per month provides 100,000 requests daily and Streaming at $79 per month provides 1 million, both including HMAC-signed webhooks that push line movements and settled results as they occur. Official SDKs for Python, Node, MCP, and CLI round out the integration experience, making PropLine a compelling choice for serious bettors and developers who need reliable, extensive data.

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 quality and excellent value
Updated: Aug 24 2026SummaryI could not be happier with the provider, looking to add more of their data to my system and try out all the features.
PositiveGreat 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.
NegativeI 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 2026SummaryI 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 closeNegativeReally 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.

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.
