Circa Odds API: Access America's Sharpest Sportsbook Data
Learn how to access Circa Sports odds through API providers and why Circa lines are the US benchmark for sharp bettors
What is Circa Sports and Why It Matters
Circa Sports is widely regarded as the sharpest sportsbook in the United States. Based in Las Vegas and operated by Circa Resort & Casino, Circa has built a reputation for:
- Welcoming Winners: Unlike most US sportsbooks, Circa doesn't limit or ban winning bettors
- Highest Limits: Offers the highest betting limits in Las Vegas, especially on NFL
- Low Margins: Competitive odds with lower juice than recreational books
- Sharp Lines: Considered the US benchmark for efficient, sharp pricing
- Circa Million & Survivor: Hosts the world's largest football contests
For US-focused bettors and developers, Circa closing lines serve as the domestic equivalent of Pinnacle - the standard for measuring betting skill and closing line value (CLV) in American markets.

Why Circa Odds Matter
The US Sharp Book Benchmark
While Pinnacle is the global standard for sharp odds, Circa serves as the US domestic benchmark. Here's why:
- Legal US Market: Circa operates legally in Nevada and other regulated states
- NFL Authority: Their NFL lines are considered among the sharpest in the world
- High Stakes Action: Large limits attract professional bettors who move markets
- No Limiting: Winners aren't restricted, creating honest price discovery
Circa vs. Pinnacle
Both are sharp books, but they serve different purposes:
- Pinnacle: Global benchmark, offshore, wider sports coverage, highest limits on soccer
- Circa: US benchmark, legal domestic option, highest NFL/NBA limits, contest host
Many serious bettors track both Circa and Pinnacle lines for a complete picture of market efficiency.

Why is Circa considered the sharpest US sportsbook?
Circa welcomes winning bettors (no limiting), offers the highest limits in Las Vegas, and uses sophisticated pricing models. This means their lines reflect true market consensus from professional bettors. They're the US equivalent of Pinnacle.
Should I track Circa or Pinnacle for CLV?
Ideally both. Pinnacle is the global standard with wider sports coverage. Circa is the US benchmark, particularly strong for NFL and NBA. For US sports, Circa closing lines are an excellent measure of betting skill.
Is Circa available outside Nevada?
Circa Sports has expanded to several states including Colorado and Iowa. However, their sharpest lines and highest limits are typically found at their Las Vegas locations. Online availability varies by state.
How do Circa's limits compare to other US books?
Circa offers the highest limits among legal US sportsbooks, especially on NFL. While recreational books like DraftKings may limit you to a few thousand dollars, Circa accepts six-figure NFL bets from known sharp bettors.
