About

PropLine is a real-time sports betting odds API covering 110+ books and 70+ sports and leagues: US sportsbooks (DraftKings, FanDuel, BetMGM, Fanatics, Hard Rock, BetRivers), Pinnacle, DFS sites (PrizePicks, Underdog, Sleeper), prediction markets (Kalshi, Polymarket) and exchanges (Betfair, Smarkets, Novig, ProphetX). Every player prop is graded against the official box score: each Over/Under ships with won/lost/push/void plus the real stat. Five books stream in real time (about one second per line move). Pricing is per request, not per credit, and the response format is the-odds-api compatible, so switching is a base-URL change. Free tier: 1,000 requests/day, no card. Hobby $9/mo (5,000/day) unlocks every analytics feature: graded results, cross-book +EV, line history and opening/closing lines. Pro $19/mo (25,000/day) adds CSV exports; Streaming Lite $39/mo (250,000/day) and Streaming $79/mo (1M/day) add webhooks and a websocket. Python, Node, MCP and CLI SDKs.

Pros & Cons from Real Users

Pros

  • I love this company hands down, I have researched and tried many! The ODDS API is horrrrible compared to Propline for starters the credits are 10x more for API calls, the price and breadth of odds it just beats many and they keep adding improvements! Andy is awesome, truly! Email responsiveness has been the most trustworthy part. Not to mention that Andy has actively listened to my suggestions about the platform, tested the requests and some have been implemented if there was genuine value!!! I love Prop-line I truly do and its my best kept secret. A true gem that if you find them then you were supposed to ! Thank you for everything and I'm a proud member. I have tried parlayapi, theoddsapi, oddspapi is grossly expensive, man i can keep going on and on the rundown is restrictive and costs more for less calls per day I have reviewed the all Propline is the best one I have found!
  • 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.
  • - 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 close
  • -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.
  • 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.

Cons

  • None at all, anything I thought could benefit the platform Andy checked out and got to work on it immediately and any questions were answered within 24 hours.
  • 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.
  • 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.
  • 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.
  • 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.
