Live Odds Data Feed — 5 Providers Compared
Choosing the right live odds feed for arb detection, dashboards, or betting bots? We compare delivery methods, latency, coverage, and pricing across the top providers.
Key Facts
- SharpAPI's SSE feed delivers odds from 43 US sportsbooks with sub-89ms P50 latency starting at $0/month.
- Don Best has provided XML odds feeds to the industry for 20+ years at $500+/month with no free tier.
- The Odds API uses REST polling rather than a persistent feed — not suitable for latency-sensitive applications.
- A live odds data feed pushes line changes as they happen, eliminating the need to poll endpoints repeatedly.
The best live odds data feed for most developers in 2026 is SharpAPI. It uses Server-Sent Events (SSE) to push line changes from 43 US sportsbooks with sub-89ms median latency. Unlike REST-based providers that require polling, SharpAPI's feed delivers updates the instant a line moves. It includes built-in +EV detection, arbitrage alerts, and middles detection — analytics that competitors require you to build yourself. Pricing starts at $0/month with a permanent free tier. OddsBlaze is a strong alternative for raw speed via WebSocket at $29–$249/mo. OpticOdds targets enterprise teams with 200+ books and custom pricing. Don Best remains the legacy choice for established sportsbook operations. The Odds API is the simplest option but uses REST polling, making it unsuitable for latency-sensitive use cases.
What Sets These Live Odds Feeds Apart
SSE vs WebSocket
SSE works natively in browsers and reconnects automatically. WebSocket offers bidirectional communication but requires more client-side logic. Both are push-based and sub-second.
Built-in Analytics
Only SharpAPI includes +EV detection, arbitrage alerts, and middles detection in the feed itself. Every other provider delivers raw odds — you build the math.
US Book Depth
SharpAPI covers 43 US-licensed sportsbooks — the deepest US-focused coverage. OpticOdds has the most global coverage (200+). Breadth vs depth matters for your use case.
Transparent Pricing
SharpAPI and OddsBlaze publish pricing publicly. Don Best, OpticOdds, and MetaBet require sales calls. The Odds API publishes tiers but is REST-only.

Provider Breakdown
SharpAPI — Best for Developers Building on US Markets
SSE-based feed covering 43 US sportsbooks. Sub-89ms P50 latency with built-in +EV detection, arbitrage alerts, and middles detection. Official TypeScript SDK with full IntelliSense. Free tier available (12 req/min, no credit card). Paid plans: $79/mo (Hobby), $229/mo (Pro), $399/mo (Sharp). Best choice for developers who want analytics out of the box without building cross-book comparison logic.
OddsBlaze — Fastest Raw WebSocket Feed
WebSocket-based feed focused on raw speed. Claims ~50ms latency for line changes. Covers 20+ US sportsbooks. Pricing: $29/mo (Basic) to $249/mo (Pro). No free tier. Good Python and JavaScript examples but no official SDK. Best for traders who need the absolute fastest raw data and will build their own analytics layer.
Don Best — Legacy Enterprise XML Feed
Industry veteran providing XML-based odds feeds for 20+ years. Used by established sportsbooks and trading desks. Pricing starts at $500+/mo with enterprise contracts. No free tier, no self-service signup. Higher latency (~500ms+) due to XML parsing overhead. Best for established operations already integrated with legacy systems that cannot easily switch protocols.
The Odds API — Simple REST (Not a True Feed)
REST-based API covering 40+ sportsbooks globally. You poll endpoints on an interval — there is no persistent connection or push delivery. Free tier available (limited requests). Paid plans start at $30+/mo. Easy to integrate with any language. Best for simple dashboards and batch analytics where real-time latency is not critical. Not suitable for arb detection or live betting bots.
OpticOdds — Enterprise-Scale Global Coverage
WebSocket and SSE feeds covering 200+ sportsbooks globally. Sub-second latency. Targets enterprise operators and trading desks. Custom pricing only (sales call required). No free tier, no self-service signup. Best for enterprise teams that need maximum book coverage across global markets and have budget for custom contracts.
MetaBet — Undisclosed Pricing Feed
Live odds feed with undisclosed pricing and coverage details. Contact sales for information. Limited public documentation makes direct comparison difficult. Listed here for completeness as a known provider in the space.
Which Feed Should You Choose?
The right live odds feed depends on your use case, budget, and technical requirements.
Arbitrage Detection
Choose SharpAPI (built-in arb detection, $79+/mo) or OddsBlaze (fastest raw data, $29+/mo). Avoid REST-based providers — polling delays mean missed arbs.
Live Dashboard
Choose SharpAPI (SSE works natively in browsers with EventSource). WebSocket feeds work too but require more client-side code. REST polling creates stale data.
Betting Bot / Automation
SharpAPI or OddsBlaze for speed. SharpAPI's +EV detection saves you from building your own edge-finding logic. Both support persistent connections ideal for automated systems.
Enterprise / Global Coverage
OpticOdds (200+ books, enterprise support) or Don Best (legacy industry standard). Budget: $500+/mo minimum. Both require sales conversations.
Frequently Asked Questions
What is a live odds data feed?
A live odds data feed is a persistent connection that pushes real-time line changes from sportsbooks to your application as they happen. Unlike REST APIs where you poll for updates, a feed delivers data the instant it changes — typically via SSE (Server-Sent Events) or WebSocket protocols. This eliminates polling overhead and ensures you never miss a line movement.
What is the difference between an odds feed and an odds API?
An odds API uses request-response (REST) — you ask for data, it responds. An odds feed uses push-based delivery (SSE or WebSocket) — data streams to you automatically when lines move. Feeds are better for latency-sensitive applications like arbitrage detection and live dashboards. APIs are simpler for batch queries and historical lookups. SharpAPI offers both: SSE streaming for real-time feeds and REST endpoints for on-demand queries.
Which live odds feed is best for building a dashboard?
For dashboards, SSE (Server-Sent Events) feeds are ideal because they work natively in browsers without additional libraries. SharpAPI uses SSE, which means you can connect directly from a frontend with EventSource — no WebSocket libraries or server-side proxies needed. OddsBlaze and OpticOdds use WebSocket, which requires more setup for browser-based dashboards.
Can I get a free live odds feed?
SharpAPI is the only provider offering a free tier with streaming access. The free plan includes 12 req/min (17,280 requests/day) with SSE support and covers 2 sportsbooks. No credit card required. OddsBlaze, Don Best, OpticOdds, and MetaBet have no free tier. The Odds API offers a free tier but only supports REST polling, not a true live feed.
What feed type is best for arbitrage detection?
For arbitrage detection, you need the lowest possible latency and push-based delivery. SSE and WebSocket feeds are both suitable — they deliver updates in under 100ms. REST polling introduces delays between requests and can miss short-lived arb windows. SharpAPI provides SSE with sub-89ms P50 latency plus built-in arbitrage detection, so you do not need to build cross-book comparison logic yourself.
How much does a live odds data feed cost?
Pricing varies widely. SharpAPI: $0–$399/mo (transparent, self-service). OddsBlaze: $29–$249/mo (published pricing). The Odds API: $30+/mo (REST only, not a true feed). Don Best: $500+/mo (enterprise XML feed, legacy contracts). OpticOdds: custom enterprise pricing (sales call required). MetaBet: undisclosed (contact sales). SharpAPI and OddsBlaze are the only providers with fully transparent, self-service pricing.
Do I need a dedicated server to consume a live odds feed?
No. SSE feeds like SharpAPI can be consumed from any environment — a browser tab, a $5/mo VPS, a serverless function, or a local development machine. WebSocket feeds (OddsBlaze, OpticOdds) have similar lightweight requirements. The only exception is Don Best XML feeds, which often require dedicated infrastructure due to their legacy delivery format and high bandwidth.
Which odds feeds cover US sportsbooks?
SharpAPI covers 43 US-licensed sportsbooks including DraftKings, FanDuel, BetMGM, Caesars, Bet365, and Pinnacle — the deepest US-focused coverage. OddsBlaze covers major US books. The Odds API covers 40+ books (US and international). OpticOdds covers 200+ books globally with strong US coverage. Don Best covers major US books but at enterprise pricing. MetaBet coverage details are not publicly documented.
