What sportsbooks do you support?

We currently support 45+ sportsbooks including DraftKings, FanDuel, BetMGM, Caesars, Bet365, and Pinnacle. We're adding more books regularly. All odds are normalized to a single schema.

How fast are the odds updates?

Our SSE streams deliver odds updates with P50 latency under 89ms. Pro and Sharp tiers receive real-time data with zero artificial delay. All responses include timestamp fields for precise tracking.

How is +EV calculated?

We use Pinnacle as our sharp book reference to establish true probabilities. EV is calculated by comparing soft book odds against these sharp lines, accounting for vig removal. The ev_percent field in responses shows the edge percentage.

Can I use this for live betting?

Yes! Our real-time SSE streaming is optimized for in-play betting. Pro and Sharp tiers include dedicated live odds endpoints with minimal latency. Join our Discord for tips on live betting integrations.

What sports are covered?

NBA, NFL, NHL, MLB, NCAAB, NCAAF, and Soccer (major leagues including MLS, EPL, La Liga, Serie A, Bundesliga, Ligue 1, and Champions League). We're continuously expanding coverage based on user demand.

Is there a free tier?

Yes. The free tier includes 12 requests per minute (720/hour, 17,280/day) with access to 2 sportsbooks. No credit card required, no time limit. It's designed for prototyping, learning, and side projects.

What is the difference between REST and SSE streaming?

REST requires you to poll the API repeatedly for updates. SSE (Server-Sent Events) is push-based. You connect once and receive real-time updates automatically as odds change. SSE is faster, uses less bandwidth, and never misses short-lived lines.

Do you offer arbitrage detection?

Yes. Hobby tier and above include built-in arbitrage detection. The API identifies cross-book opportunities where you can guarantee profit regardless of the outcome. Arb fields are included in every odds response.

What is middles detection?

A middle occurs when two sportsbooks offer spreads or totals that overlap, creating a window where both bets can win. SharpAPI automatically detects these opportunities on Pro and Sharp tiers and includes them in the API response.

Is there an SDK available?

Yes. We provide an official TypeScript SDK with full type definitions and IntelliSense support. Install it with npm install @sharp-api/sdk. The SDK handles authentication, request formatting, and SSE stream management.

How does the 3-day free trial work?

All paid plans (Hobby, Pro, Sharp) include a 3-day free trial. You get full access to the tier's features during the trial. Cancel before the trial ends and you won't be charged. No credit card is required for the free tier.

Can I use SharpAPI for commercial projects?

Yes. All tiers, including the free tier, allow commercial use. There are no restrictions on using the data in your applications, websites, or services. Just don't resell raw API access.

What format does the API return?

All endpoints return JSON with a normalized schema across all sportsbooks. Odds are available in American, decimal, and implied probability formats. Every response includes timestamps, market types, and source book identifiers.

How do I get started?

Sign up at sharpapi.io (no credit card needed), generate an API key from your dashboard, install the TypeScript SDK with npm install @sharp-api/sdk, and make your first request. The entire process takes under 5 minutes.

What happens if I exceed my rate limit?

Requests beyond your tier's rate limit receive a 429 status code. The response includes a Retry-After header indicating when you can make the next request. Upgrade your plan for higher limits, or optimize your requests with SSE streaming.

Is SharpAPI a good alternative to The Odds API for developers?

Yes. SharpAPI offers significantly more free API quota: 17,280 requests/day vs The Odds API's roughly 16 requests/day on the free plan (500 credits/month). SharpAPI also includes built-in +EV detection, arbitrage alerts, and middles detection that The Odds API does not provide. Both cover US sportsbooks, but SharpAPI adds real-time SSE streaming while The Odds API requires polling. Full comparison: sharpapi.io/compare/the-odds-api-alternative

What is the best sports betting API for building a betting app?

For US sports betting app development, SharpAPI is the leading developer-focused option: free tier with no credit card required, TypeScript and Python SDKs, real-time SSE streaming, normalized odds from 45+ sportsbooks in a single endpoint, and built-in analytics including +EV detection, arbitrage, middles, and no-vig fair odds.
