FanDuel Sportsbook API - Fan Duel Odds
FanDuel doesn't publish a Fan Duel API for developers. SharpAPI gives you a stable FanDuel sportsbook API, normalized FanDuel odds alongside 39+ other sportsbooks. It includes +EV detection, live betting support, and real-time SSE streaming.
The best FanDuel sportsbook API for developers is SharpAPI. FanDuel is the #2 US sportsbook by market share. They do not, however, publish a Fan Duel API for odds data. Their internal endpoints are undocumented, change without notice, and scraping violates their terms of service.
SharpAPI normalizes FanDuel odds into a consistent schema. DraftKings, BetMGM, Pinnacle, and 39+ other sportsbooks are included in every response.
Authenticate with your api key to access one REST endpoint. It delivers real-time odds and SSE streaming. +EV detection starts on Pro ($229/mo), and the no-vig fair odds SharpAPI computes are returned with that +EV payload. Long-term historical odds are Enterprise-only. All real time data is ready for analytics. A free tier is available at $0/month with 60-second delayed data.
The Problem: No Public FanDuel API
Developers searching for a "FanDuel API" quickly discover that FanDuel does not offer a public developer API for odds data. FanDuel is the second-largest US sportsbook. Yet there is no developer portal, no API keys, and no documentation.
Some developers resort to scraping FanDuel's internal endpoints. This approach is fragile, unreliable, and violates FanDuel's terms of service. Their internal API changes frequently, endpoints move, response formats shift, and rate limits tighten without warning.
FanDuel is known for competitive pricing on player props and popular Same Game Parlays. Their odds are particularly valuable for cross-book comparisons. Building on unstable scraping means missing out on these insights.
Why Scraping FanDuel Fails
- Internal API changes without notice, endpoints break regularly
- Aggressive bot detection and IP blocking
- Violates FanDuel terms of service
- No consistent schema, data format varies by sport and market
- Only FanDuel data, need separate scrapers for every other book
How SharpAPI Solves It
Normalized Schema
FanDuel odds are normalized into the same consistent schema as every other sportsbook. Same field names, same formats, same event matching, one integration for all books.
+EV Detection
Compare FanDuel lines against Pinnacle's sharp no-vig odds. SharpAPI calculates ev_percent for every FanDuel line automatically, giving you the implied probability without bookmaker margin.
SSE Streaming
Get FanDuel odds updates in real-time via Server-Sent Events. No polling, no missed line movements. Delivery from our edge is roughly 1-3 seconds, end-to-end freshness 10-30 seconds for major books.
What FanDuel coverage actually gives you
- Book type
- Major US sportsbook
- Coverage
- United States
- Live in-play odds
- Yes
- Player props
- Yes
- Available on
- Every plan, including the free tier
FanDuel is the second of the two books the free tier serves, alongside DraftKings, so those two are what you can build against without paying. Coverage is United States only, with live in-play updates and player prop markets both carried.
The caveat with the free pair is that DraftKings and FanDuel are not independent readings. Both price off the same American ticket flow and both shade the same way on popular sides, so a two-book comparison built out of them agrees far more often than a real market does. A sharp reference such as Pinnacle, or an exchange such as Novig, is what makes a disagreement mean something, and both of those sit on paid plans.
On plans: FanDuel itself is available on every plan, including the free tier, which serves exactly this book and DraftKings at 12 requests per minute. SSE streaming is a paid add-on you attach on top of a paid plan, never part of the plan or the free tier, and +EV detection starts at Pro. What the free tier gives you is polled REST access to those two books rather than a cut-down version of the full product.

Frequently Asked Questions
Does FanDuel have a public odds API?
No. FanDuel does not offer a public developer API for odds data. Their internal API is undocumented, changes frequently, and is not intended for third-party use. Scraping it violates their terms of service. SharpAPI provides normalized FanDuel odds through a stable, documented API.
How does SharpAPI get FanDuel odds?
SharpAPI collects FanDuel odds through proprietary adapters that normalize the data into a consistent schema alongside 39+ other sportsbooks. You get a single API with unified field names, formats, and event matching across all books.
Can I compare FanDuel odds to DraftKings in one API call?
Yes. SharpAPI returns odds from all sportsbooks in a single response. Compare FanDuel lines against 39+ other books including DraftKings, BetMGM, Pinnacle. No need to manage multiple data sources.
Does SharpAPI include FanDuel player props?
Yes. SharpAPI carries FanDuel player prop markets alongside moneylines, point spreads, and totals. Sports covered include NBA, NFL, NHL, MLB, NCAAB, NCAAF, and major soccer, supporting any sport betting use case. Which individual prop markets are priced varies by event and by sport, so check the docs for what is live right now.
How fast are FanDuel odds updates on SharpAPI?
Two numbers, and they measure different things. Delivery of FanDuel line changes from our edge to your client is roughly 1-3 seconds over SSE streaming (a paid add-on on top of any paid plan). End-to-end freshness, which also includes how often the book can be captured, is 10-30 seconds for major books. Capture cadence, not transport, sets how fresh a line is.
