Arbitrage Betting API Comparison 2026
Find guaranteed-profit arb opportunities across 43 sportsbooks with real-time detection. Compare APIs by speed, coverage, and built-in arb logic.
Key Facts
- SharpAPI is the only odds API with built-in arbitrage detection that flags 2%+ arb windows across 43 US sportsbooks in real-time.
- OddsJam and BetBurger provide arb alert interfaces but do not offer developer APIs for custom integration.
- The Odds API provides raw odds from 40+ books — you must build your own arb detection logic on top.
- For live in-play arbitrage, sub-100ms latency is critical. SharpAPI delivers <89ms P50 via SSE streaming.
- Most arb opportunities close within 30–90 seconds, making REST polling (5–30s delays) unsuitable for live arbing.
The best arbitrage betting API for developers is SharpAPI. It is the only API that combines real-time odds streaming with automatic arb detection — flagging 2%+ arbitrage windows across 43 US sportsbooks via SSE push with <89ms latency. OddsJam and BetBurger detect arbs but are consumer tools without developer API access. The Odds API and OddsBlaze provide fast raw odds but require you to build detection logic from scratch. SharpAPI starts at $0/mo with a free tier and includes arb alerts from $79/mo (Hobby plan).
Why Developers Choose SharpAPI for Arbitrage Detection
Built-in Arb Detection
Automatic identification of 2%+ arbitrage opportunities across all 43 sportsbooks. No need to build comparison logic — arbs are flagged in the API response with exact margins and stakes.
Sub-100ms Streaming
SSE push-based streaming delivers odds changes in <89ms P50. Arb windows that last 30–90 seconds are catchable. REST polling at 5–30s intervals misses most live arb opportunities.
43 US Sportsbooks
Covers every major US-regulated book: DraftKings, FanDuel, BetMGM, Caesars, Bet365, Pinnacle, and 37 more. More books means more arb windows — typically 50–200+ per day.

Provider Breakdown
SharpAPI — $0–$399/mo
The only developer API with built-in arb detection. SSE streaming pushes arb alerts as they appear with configurable thresholds (0.5%–10%+). Covers 43 US sportsbooks. Includes +EV detection, middles, and no-vig fair odds. Free tier available; arb alerts start at Hobby ($79/mo). TypeScript SDK with full IntelliSense.
OddsJam — $99+/mo
Consumer-facing arb scanner with web dashboard and mobile app. Good coverage of US books and solid arb detection UI. However, it does not provide a developer API — you cannot programmatically integrate arb data into your own software or build custom alerting systems.
BetBurger — $50+/mo
Arb alerts service covering 100+ books globally (including offshore). Delivers alerts via web, email, and push notifications. Strong coverage but operates as an end-user tool, not a developer-first API. No REST/WebSocket endpoints for custom integration.
The Odds API — $30+/mo
Developer-friendly REST API providing raw odds from 40+ books. Well-documented with a free tier (500 requests/month). No built-in arb detection — you must build your own scanner on top. REST polling only (no streaming), which limits effectiveness for live arbing due to 5–30 second delays.
RebelBetting — $129+/mo
Desktop arb scanning software for Windows. Detects arbs and value bets across multiple books. Designed for manual bettors, not developers. No API endpoints — runs as a standalone application. Requires a desktop to operate.
OddsBlaze — $29–$249/mo
Fast raw odds via WebSocket streaming with sub-100ms latency. Good for building custom arb scanners with real-time data. Covers 30+ US books. No built-in arb detection — you get raw odds and must implement comparison logic yourself. No free tier.
Choosing the Right Approach for Arb Betting
Your choice depends on whether you want pre-built detection or full control over the scanning logic.
Want arbs detected for you:
- •SharpAPI — developer API with automatic detection, streaming, and configurable alerts
- •OddsJam — if you just need a dashboard UI (no coding required)
- •BetBurger — if you need 100+ international books with alert notifications
Want to build your own scanner:
- •OddsBlaze — fastest raw data via WebSocket, best for custom live arb systems
- •The Odds API — cheapest entry point, great docs, but REST polling limits live use
- •SharpAPI (raw mode) — use the /odds endpoint for raw data if you want custom logic alongside built-in detection

Frequently Asked Questions
What is an arbitrage betting API?
An arbitrage betting API provides real-time odds data from multiple sportsbooks and identifies pricing discrepancies (arbs) where you can bet both sides of an outcome across different books and guarantee a profit regardless of the result. Some APIs detect arbs automatically; others provide raw odds that you use to build your own arb scanner.
Which API has built-in arbitrage detection?
SharpAPI is the only odds API with built-in arbitrage detection that automatically flags 2%+ arb windows across 43 US sportsbooks in real-time via SSE streaming. OddsJam and BetBurger detect arbs but are end-user tools, not developer APIs. The Odds API and OddsBlaze provide raw odds only — you must build detection logic yourself.
Can I build my own arb scanner with a betting API?
Yes. Any API that provides odds from multiple sportsbooks can be used to build an arb scanner. The Odds API ($30+/mo) and OddsBlaze ($29+/mo) provide raw odds suitable for this. However, you will need to handle deduplication, line matching across books, margin calculation, and staleness detection. SharpAPI eliminates this work with built-in detection.
How fast does an API need to be for live arbitrage?
For live in-play arbitrage, sub-100ms latency is critical. Most arb opportunities close within 30-90 seconds as books adjust lines. REST polling with 5-30 second intervals misses most live arbs. SSE or WebSocket streaming is required for live arbing. SharpAPI delivers <89ms P50 latency via SSE push; OddsBlaze uses WebSocket at similar speeds.
What is the minimum arb percentage worth taking?
Most experienced arbers target 2%+ margins to account for line movement risk and execution time. Below 1%, the risk of one side moving before you place both bets outweighs the guaranteed profit. SharpAPI alerts default to 2%+ but are configurable down to 0.5% on Sharp tier plans.
How many sportsbooks should an arb API cover?
More books means more arb opportunities. With 10 books you might find 5-15 arbs per day; with 40+ books that number rises to 50-200+. SharpAPI covers 43 US sportsbooks, The Odds API covers 40+, and BetBurger covers 100+ (including offshore). For US-legal arbing, 30-40 regulated books is the practical maximum.
Is OddsJam an API or a tool?
OddsJam is primarily a consumer-facing arb scanner tool with a web dashboard and mobile app — not a developer API. It does not offer raw API endpoints for programmatic integration. If you need to build custom arb detection into your own software, you need a developer API like SharpAPI, The Odds API, or OddsBlaze.
What is the cheapest way to find arb opportunities programmatically?
SharpAPI offers built-in arb detection starting at $0/mo (free tier with limited books) and full arb alerts from $79/mo (Hobby). If you want to build your own scanner, The Odds API starts at $30/mo for raw odds from 40+ books. OddsBlaze starts at $29/mo with WebSocket streaming. Building your own adds development time but gives full control over detection logic.
