SharpAPI Review 2026

SharpAPI is a sports odds API that does not stop at raw lines. On top of the standard odds endpoints, it exposes pre-computed opportunity feeds: +EV bets (using Pinnacle as the no-vig anchor), cross-book arbitrage with stake calculations, middles, and low-hold lines. You can pull the raw odds and run your own math, or skip that step and consume the opportunity endpoints directly.

The API covers 35+ sportsbooks across five sports (NBA, NFL, MLB, NHL, soccer) with REST, SSE streaming, and an optional WebSocket add-on. A TypeScript SDK with full IntelliSense ships alongside the REST docs. Authentication uses an X-API-Key header, with Bearer and query-parameter fallbacks for SSE.

The draw here is the opportunity layer. Four dedicated endpoints surface edges without requiring you to build the detection logic yourself:

• /opportunities/ev flags positive expected-value bets by comparing each book's price against Pinnacle's no-vig line. Available on Pro ($229/mo) and above.
• /opportunities/arbitrage finds cross-book arb pairs and returns the stake split. Available from Hobby ($79/mo).
• /opportunities/middles identifies overlapping spread or total windows across books. Pro and above.
• /opportunities/low_hold surfaces the tightest combined hold across two sides of a market. Pro and above.

If you have used other odds APIs, you know that building reliable arb and EV detection means handling edge cases around stale lines, market suspensions, and different line formats. SharpAPI absorbs that complexity on its side. The trade-off: you trust their detection logic rather than tuning your own, and the best endpoints are gated behind the Pro tier at $229/mo.

Four tiers, plus add-ons:

• Free ($0/mo): 12 requests/minute, 2 sportsbooks (DraftKings and FanDuel only), pre-match odds with a 60-second delay. No card required.
• Hobby ($79/mo): 120 requests/minute, 5 sportsbooks, real-time data, arbitrage detection. 3-day free trial.
• Pro ($229/mo): 300 requests/minute, 15 sportsbooks. Adds +EV, middles, low hold, and betting splits. 3-day trial.
• Sharp ($399/mo): 1,000 requests/minute, 25 sportsbooks. Adds sharp books (Pinnacle access), priority support. 3-day trial.

Add-ons: WebSocket streaming is $99/month on top of any paid plan. Live game state (scores, clock, period) is another $79/month. Historical closing odds are listed as enterprise-only.

The free tier is useful for prototyping but limited: two books and a 60-second delay mean you cannot test real-time workflows or the opportunity endpoints without upgrading. The sportsbook count also scales with price. On Hobby you see 5 books, which is narrow for arb scanning. You need Pro at $229 to unlock 15 books and the full opportunity suite, and Sharp at $399 for the full 25-book set including Pinnacle.

The REST API lives at https://api.sharpapi.io/api/v1. Core endpoints cover odds snapshots (/odds), best-available odds (/odds/best), odds deltas (/odds/delta), closing lines (/odds/closing), events, deeplinks, and batch requests. Response times are advertised as sub-100ms on average, with 47 million odds processed daily.

Real-time delivery has two paths. SSE streaming (/stream) pushes updates over a standard HTTP connection. WebSocket is a separate $99/month add-on, not included in any base plan. If your stack relies on WebSocket, factor that into the total cost.

A few things to know before you build. Sport coverage is limited to five: NBA, NFL, MLB, NHL, and soccer. If you need tennis, golf, esports, or college sports, this is not the right API. Historical closing odds are enterprise-only, so backtesting against real closing lines requires either storing the stream yourself or negotiating a custom contract. The site does not publish the full list of sportsbooks per tier, so confirm which books are on Hobby vs Pro vs Sharp before you commit. For a broader comparison of odds APIs with wider sport and book coverage, see the sports odds API directory.

The opportunity endpoints define the audience. If you want pre-computed +EV, arb, and middles feeds and do not want to build that detection pipeline yourself, SharpAPI saves you real engineering time. That suits:

• Solo bettors and small teams who want arb and EV alerts without maintaining their own scanner.
• Prototype builders who need a working +EV feed to demo or test a product idea quickly.
• TypeScript developers who value a typed SDK with IntelliSense over raw REST calls.

Skip it if you need broad sport coverage (only five sports), if you need more than 25 sportsbooks, or if you want to control your own EV and arb logic end to end. Skip it too if WebSocket is a core requirement on a tight budget, since the $99/month add-on pushes the real cost above the sticker price. Developers who already have their own detection stack get less value from the opportunity endpoints and may prefer a raw odds feed with wider coverage.

Most odds APIs sell you data and leave the math to you. SharpAPI sells you the math on top of the data. That is a genuine time-saver if you want arb or EV detection out of the box, but it comes with constraints that raw-data APIs do not impose.

The sportsbook count maxes out at 25 on the top tier. Providers focused purely on aggregation offer 40 to 350+ books for similar or lower prices. Sport coverage is five leagues, which is thin next to APIs covering 30 or more. Historical data is enterprise-gated. And the opportunity endpoints are only as good as their detection logic, which you cannot inspect or tune.

Think of SharpAPI as a convenience layer. If the convenience matches your workflow and the coverage fits your sports, the time saved is real. If you outgrow the detection logic or need broader data, you will likely move to a raw feed and build your own pipeline. The free odds API comparison covers alternatives with wider coverage at the entry level.

SharpAPI is a solid pick for developers who want pre-built opportunity detection without building it from scratch. The +EV, arbitrage, and middles endpoints save real engineering work, the TypeScript SDK is well-typed, and the free tier lets you test the data model without a card.

The limits are straightforward. Five sports, 25 books maximum, historical data behind an enterprise gate, and WebSocket as a paid add-on. If those constraints fit your project, grab the free key and test the opportunity feeds against your use case. If you need wider coverage or full control over the detection logic, look at the broader aggregators in the directory.
