Comparing the Best Odds API Providers

Picking an odds API provider is less about finding "the best" one and more about matching a provider's pricing model and feature set to what you're actually building. A solo developer prototyping a moneyline tracker has wildly different needs than a sportsbook operator running live in-play trading, and the gap between the cheapest self-serve option and an enterprise feed with a sales call attached is enormous, both in price and in what you get for it.

The six Odds API Providers below span that full range: low-cost, self-serve APIs built for hobbyists and small teams, sharp-money data feeds for professional bettors, and enterprise-grade platforms built for sportsbooks and trading desks. Below is a side-by-side breakdown of pricing, coverage, and core features for each, followed by a closer look at where every provider actually fits.

We Compare 6 Odds API Providers

All six providers offer live and closing odds. Futures and same-game parlay (SGP) markets are not currently part of the SportsGameOdds feed — if either is central to what you're building, OpticOdds and Unabated both carry them. Competitor pricing and features are as published at the time of writing; check directly with each provider before committing.

The pricing model column is the one most teams underestimate. A headline rate of $25/month tells you very little if the billing unit is a market-region pair rather than an event, because the cost scales with how wide you cast your net rather than with how many games you actually care about. The section on The Odds API below works through what that means in practice.

Each provider below also has a dedicated head-to-head page with SportsGameOdds — browse them all on our odds API comparison hub.

SportsGameOdds

Key Overview

• Free Tier: Available, plus a 7-day free trial on paid plans.
• Pricing: $149/month for Rookie and $499/month for Pro, or $99 and $299 per month respectively when billed yearly.
• Features: Offers live odds, game results, closing odds, settlements and deeplinks. Futures and same-game parlay (SGP) odds are not provided.
• Additional Information: 85+ bookmakers, including DraftKings, FanDuel, BetMGM, and Caesars in the US, plus major European books, across 67+ leagues and 28+ sports. Documentation is public and needs no signup to read.
• Website: www.sportsgameodds.com

SportsGameOdds is the provider that comes up most consistently when developers ask for a recommendation that doesn't require a sales call, a contract negotiation, or a week of onboarding. The pitch is straightforward: transparent pricing, a genuine free tier, and documentation that lets you evaluate the product before spending a penny. For most teams building betting tools or odds-driven applications, that's exactly where you want to start.

SportsGameOdds covers 85+ bookmakers including the Pinnacle Odds API, DraftKings, FanDuel, BetMGM, Caesars, and major European books, with data delivered in JSON via both REST and WebSocket. The REST endpoints handle standard polling use cases, while the WebSocket connection pushes real-time updates for live in-play markets without the overhead of repeated requests. Both are available from the same integration, so you're not choosing between architectures upfront.

What makes the billing model genuinely different from most competitors is the object-based pricing structure. Each event counts as one object regardless of how many bookmakers or markets you pull for that event. If you request NFL odds across ten sportsbooks for a game, that's one object, not ten. For platforms that need broad market coverage, this is a meaningful cost advantage over credit-based systems that charge you more the wider you cast your net.

Historical data, closing odds, scores, and settlement data are all included across every pricing tier, which means you don't need a second provider to handle results or bet grading. The documentation covers quickstart examples in JavaScript, Python, Ruby, Go, and Java, with official SDKs in five languages: JavaScript/TypeScript, Python, Ruby, Go, and Java. Support is available via Discord for community questions and directly through the team for paid plan subscribers.

The free tier allows 10 requests per minute and 2,500 objects per month with odds updating every 10 minutes. Paid plans start at $149 per month, or $99 per month billed yearly.

SportsGameOdds also supports vibe coding through the AI-assisted development odds API.

Best for: Developers and small-to-medium betting platforms that want to get up and running quickly without going through a sales process. The object-based billing, self-serve free tier, and bundled scores and settlement data make it the most practical starting point for most teams building odds comparison tools, analytics products, or betting platforms focused on US sports and major international leagues.

The Odds API

Key Overview

• Free Tier: Available.
• Pricing: Plans start at $25 per month and scale by request volume.
• Features: Provides live odds, game results, closing odds, and futures. Deeplinks, SGP odds, and bet settlement are not included.
• Additional Information: The-Odds-API covers odds from numerous global bookmakers, including DraftKings, FanDuel, BetMGM, and Caesars in the US. The API delivers data in JSON format and offers add-ons for Google Sheets and Excel.
• Website: www.the-odds-api.com

The Odds API has been around since 2017 and built a strong reputation in developer communities largely because it was one of the first providers to offer transparent self-serve pricing without requiring anyone to fill out a contact form. That head start matters. It shows up in developer forums, Reddit threads, and comparison posts more than almost any other provider in this space, and the community knowledge base around it is correspondingly deep.

The product itself is a clean, well-documented REST API that returns odds in JSON format. Coverage spans 70+ sports and 40+ bookmakers including Bet365, DraftKings, FanDuel, and William Hill, with data available for mainstream US and European markets. Historical odds data goes back to 2020, and there are add-ons for Google Sheets and Excel that make it accessible to analysts and non-developers who want to work with odds data without writing any code.

Where it gets more nuanced is the billing model. The Odds API uses a credit-based system where each request costs credits proportional to how many markets and regions you query. A single request pulling odds across two regions and three markets costs six credits rather than one. Historical odds queries cost ten times the standard credit rate, which becomes a real constraint for anyone doing serious backtesting at scale. The free tier provides 500 credits per month, which is enough to get a feel for the data but runs out quickly in any meaningful application.

Bookmaker coverage is another consideration worth understanding upfront. The 40+ books covered are predominantly mainstream soft books. Sharp books like Pinnacle and Betfair Exchange are not included, which rules it out for anyone building models that rely on sharp line movement as a reference point.

Paid plans start at $25 per month for 20,000 requests, scaling up through several tiers based on request volume.

Best for: Hobbyist developers, solo bettors, and small platforms that want a well-documented, low-friction entry point into odds data with transparent pricing they can evaluate before committing. Works well for projects that query a limited number of markets at moderate frequency. Teams that need sharp book coverage, high-frequency polling across many markets, or affordable historical data access at scale will likely find the credit model becomes a constraint sooner than expected.

OddsJam

Key Overview

• Free Tier: Not available.
• Pricing: Contact for details.
• Features: Offers real-time betting odds, arbitrage opportunities, an odds API and betting tools.
• Additional Information: OddsJam provides a comprehensive suite of tools designed for sports bettors, including real-time odds comparison across multiple sportsbooks, arbitrage and middle betting opportunities, and positive expected value (EV) betting strategies. Their platform covers a wide range of sports and leagues, offering detailed insights to help users make informed betting decisions. For API access and integration details, it’s recommended to contact OddsJam directly through their website.
• Website: www.oddsjam.com

The OddsJam API provides real-time betting odds sourced from thousands of servers, delivering over one million odds per minute. Designed with bettors in mind, it suits teams refining their betting strategies, with data on injuries, scores, player props, and schedules alongside the odds. If budget is not a constraining factor it is a strong product, and a reasonable fit for football odds, scores, results and stats.

OddsJam's developer API is powered by OpticOdds, so see our SportsGameOdds vs OpticOdds comparison for the developer-facing details.

OpticOdds

Key Overview

• Free Tier: Not available. Contact required to get started.
• Pricing: Reported from around $5,000/month; custom enterprise pricing available.
• Features: Live odds, closing odds, futures, SGP odds, deeplinks, bet settlement, player props, real-time SSE streaming, Odds Screen trading tools, Copilot automated trading, and Bet Builder. Sports covered: Football, basketball, baseball, tennis, soccer, cricket, and more across 25+ sports.
• Website: www.opticodds.com

OpticOdds sits firmly at the enterprise end of the market and makes no apologies for it. Trusted by 200+ companies from startups to market leaders, including household names like BetMGM, Kambi, and Entain, it's a platform built for teams who need the fastest, most comprehensive odds data available and have the budget and infrastructure to match.

The API aggregates data from 200+ sportsbooks into a single unified odds feed, delivering odds in under 800ms, which is fast enough for live in-play markets and reliable enough for peak volume. It's the only betting data API with live odds on player props and alternate markets across 200+ sportsbooks, which is a genuine differentiator for platforms where prop markets are a core product feature rather than an afterthought.

Beyond raw odds delivery, OpticOdds has built a suite of products on top of the data feed. Their Odds Screen gives trading teams a real-time interface for monitoring line movement and spotting outliers. Their Copilot product handles automated pricing, position management, and settlement. Their Bet Builder and SGP engine generates correlated parlay combinations at scale. For a sportsbook operator looking to replace multiple vendors with a single partner, the breadth of what OpticOdds offers under one roof is hard to match.

The data is delivered via Server-Sent Events for real-time streaming rather than WebSocket, and each request can retrieve data from up to 5 sportsbooks simultaneously, with parallel requests recommended for broader coverage. The API surface is well-documented and their developer documentation covers every core endpoint with clear examples.

Pricing is not publicly listed. Based on community reports, pricing starts around $5,000 per month per sport, with custom enterprise agreements for larger integrations. There is no self-serve free tier and getting started requires going through a sales conversation.

Best for: Established sportsbook operators, large trading desks, media companies, and DFS platforms that need the broadest bookmaker coverage, the fastest delivery, and a partner that can handle pricing, settlement, and risk management as well as data. Not suitable for independent developers or early-stage platforms where budget and onboarding speed are a priority.

Unabated

Key Overview

• Free Tier: Trial available on request.
• Pricing: From $3,000/month for personal use; commercial pricing on request.
• Features: Live odds, closing odds, futures, SGP odds, deeplinks, bet settlement, WebSocket streaming, and the proprietary Unabated Line vig-free consensus.
• Additional Information: Sports covered are NFL, NBA, MLB, NHL, WNBA, College Football, College Basketball, and PGA. They offer betting tools alongside the API.
• Website: www.unabated.com

Unabated occupies a different space to most of the providers in this comparison. It's built for serious, professional bettors and the teams that support them — not for developers prototyping a side project or small platforms just getting started. If that description fits you, it's one of the most compelling products in the market. If it doesn't, the price tag will make that clear quickly.

The core product is a live sports odds API that covers sides, totals, partial games, alternate lines, DFS pick'em lines, and player props from the top sportsbooks worldwide, delivered via WebSocket with no call limits or throttling on paid plans. That last detail matters more than it might seem — most APIs at this price point still impose rate limits that can become a real constraint for high-frequency applications. Unabated doesn't.

What truly sets it apart is the Unabated Line. Their data science team crafts a vig-free consensus line for each individual sport, created with input from sharp bettors across the world and backed up with data that shows which books are the fastest to reach the closing number in each sport. For anyone building models that need a reliable fair-value benchmark rather than just raw bookmaker prices, this is genuinely valuable and not something you can replicate easily elsewhere.

The API also now includes SGP odds, deep linking, and WebSocket streaming as part of their v3.0 release, which addresses gaps that earlier versions had. Support is handled directly, with the option to integrate their team into your company Slack — a level of service that reflects the enterprise positioning.

Pricing starts at $3,000 per month for personal use, with commercial pricing available on request.

Best for: Professional bettors, sharp betting operations, and data science teams that need a vig-free consensus line, comprehensive market coverage, and real-time WebSocket delivery with no throttling. Not the right fit if you're early stage or working within a tight budget.

SportsData.io

Key Overview

• Free Tier: Available.
• Pricing: Contact for details.
• Features: Offers live odds, game results, closing odds, futures, and bet settlement. Deeplinks and SGP odds are not provided.
• Additional Information: Sports covered are NFL, NBA, MLB, NHL, NCAA Football, NCAA Basketball, PGA, NASCAR, Soccer, MMA and Tennis, plus more via their Global API. Also carries fantasy data, scores and stats, AI content automation, and interactive widgets.
• Website: https://sportsdata.io/

SportsData.io is a full-stack sports data platform that goes well beyond odds. Where most providers on this list are focused purely on delivering betting lines, SportsData.io covers live odds feeds, pricing and trading support, bet settlement, scores, stats, play-by-play data, injuries, lineups, fantasy projections, and even AI-generated content, all from a single provider. For operators who want to consolidate their data vendors rather than manage multiple integrations, that breadth is a genuine advantage.

On the odds side specifically, their API provides comprehensive pre-match, in-play, historical, and closing lines, along with an extensive selection of props and futures markets, with live odds updates and line movement timestamps. Supported bookmakers include DraftKings, FanDuel, BetMGM, Caesars, BetRivers, Circa, BetOnline, Fanatics, and ESPN BET. They also offer a proprietary BAKER Engine, which can be used as a primary or cross-check pricing engine for both standard and exotic markets including SGP, Head2Heads, and exact scores.

Their settlement verification feed is a standout feature for sportsbook operators. It bolts onto official data via mapped game, team, and player IDs and provides an alert when there's a mismatch for further investigation, which is a meaningful safeguard for any platform actually paying out bets.

A free tier is available, and documentation is thorough with workflow guides, a data dictionary, and integration tools. Pricing for full access is not publicly listed and requires contacting their team.

Best for: Media outlets, fantasy platforms, sportsbook operators, and enterprise teams that want a single vendor covering odds, stats, fantasy data, and content rather than piecing together multiple APIs. It's a bigger investment in both cost and integration complexity than the simpler providers here, but for the right use case it removes a significant amount of operational overhead.
