DraftKings does not offer a public developer API in 2026. There is no developer portal, no application form for an API key, and no documentation page you can sign up for. The integrations that exist are private, B2B only, and locked behind partnership agreements with the DraftKings business team. If you are searching for a draftkings api, you are almost certainly looking for one of three things: live sportsbook odds, fantasy lineup data, or contest results. Below is what actually exists, who can get access, and the third-party services developers use to fill the gap.
Quick Answer: Is There a DraftKings API?
- Public API: No. None.
- Developer documentation: Does not exist publicly.
- API key: Cannot be applied for as an individual developer.
- Partner integrations: Yes, B2B only via DraftKings business development.
- Reverse-engineered endpoints: Exist on GitHub but break often and violate ToS.
- Real alternative for odds: The Odds API, OddsJam, SportsRadar.
- Real alternative for fantasy lineups: pydfs-lineup-optimizer (open-source).
Why People Search for a DraftKings API
The search volume on “draftkings api” is real. It pulls hundreds of impressions a month and breaks down into three intents:
- Sportsbook odds data for arbitrage, line shopping, or building a comparison site.
- Daily fantasy data for lineup optimizers, salary tracking, or contest scraping.
- Live game data for in-game betting models or prop research.
None of these are served by an official DraftKings endpoint. The ecosystem around DraftKings data is entirely third-party or unofficial. The next sections cover what each group actually uses.
Third-Party Odds APIs Developers Actually Use
If you need DraftKings sportsbook odds, you do not call DraftKings directly. You buy from an aggregator that monitors books, including DraftKings, and resells the feed.
| Service | Free Tier | Paid Start | Covers DraftKings? | Best For |
|---|---|---|---|---|
| The Odds API | 500 req/month | $30/mo | Yes (US books) | Hobby and light use |
| OddsJam | No free tier | $300/mo+ | Yes | Pro arbitrage and +EV |
| SportsRadar | Trial only | Enterprise | Yes (partner data) | Commercial apps |
| BettingPros | Limited free | $80/mo+ | Yes | Picks plus odds blend |
| OddsAPI.io | None | $50/mo | Yes (US plus UK) | Mid-tier devs |
The Odds API is where most hobbyists start. The free tier covers small projects, and paid plans scale up to a few thousand requests per day. OddsJam is the standard for arbitrage and positive expected value tools where speed matters more than cost. SportsRadar is the route taken by media companies and licensed operators who need contractual data, not scraped data.
Fantasy Lineup Optimizers: Open-Source Tools
For DFS players building lineup optimizers, the route is open-source Python and CSV imports. DraftKings publishes a downloadable contest CSV from each contest page. That file holds player IDs, salaries, positions, and rosters. Optimizers consume it directly. No API key needed.
- pydfs-lineup-optimizer: Python library on GitHub, MIT license, supports NBA, NFL, MLB, NHL, soccer. Reads the DraftKings CSV directly.
- FantasyData and RotoWire CSV exports: projection feeds that pair with the optimizer for value scoring.
- DraftFast: older Python optimizer, less actively maintained but still works for NFL.
This is the workflow used by virtually every public DFS optimizer site you have ever seen. They are not calling a DraftKings API. They pull the public CSV and apply linear-programming math on top.
Reverse-Engineered DraftKings Endpoints
DraftKings runs internal GraphQL and REST endpoints that power the website and apps. Some are accessible without auth and have been documented in GitHub repositories such as jaebradley/draftkings_client. They return contest lists, draft groups, and player pools. They are not stable. They change without notice. They violate the DraftKings Terms of Service if used at scale.
If you ship a product on these endpoints, expect to rewrite scrapers every few months and accept that DraftKings can rate-limit, block your IP, or send a cease-and-desist. For a personal research project the legal risk is low. For a commercial product this is not a real foundation.
Becoming an Official DraftKings Data Partner
DraftKings does grant API access to selected partners: licensed operators, regulated media, and contracted data providers. The path looks like this:
- Contact DraftKings business development through the corporate partnerships form on draftkings.com.
- Provide proof of business entity, regulatory standing, and intended use case.
- Negotiate a commercial agreement, including revenue share or licensing fees.
- Sign an NDA before any technical documentation is shared.
- Receive sandbox credentials and an integration spec.
Solo developers, hobbyists, and pre-revenue startups will not pass this filter. The minimum viable partner is a registered company with revenue and a licensing case.
Geolocation and Compliance
DraftKings enforces state-by-state legality through a third-party geolocation service, GeoComply, not through a public API call. If you are building a product that needs to verify whether a user is in a legal DraftKings state, you license GeoComply directly. DraftKings does not expose this layer.
What This Means for Your Project
If your goal is to track best betting odds across books, build on The Odds API or OddsJam. If your goal is fantasy optimization, install pydfs-lineup-optimizer and import the contest CSV. If your goal is a commercial sportsbook product that integrates DraftKings markets, prepare for a multi-month partnership conversation and an enterprise contract.
What none of these paths involve: applying for a DraftKings API key on a self-serve developer page. That page does not exist.
Frequently Asked Questions
Does DraftKings have an API?
Not a public one. DraftKings has internal endpoints and partner integrations, but no self-serve developer API, no public documentation, and no API key application form for individual developers.
Where is the DraftKings developer API documentation?
There is no public DraftKings developer documentation. Documentation is shared only with contracted partners under NDA after a business-level agreement is signed.
How do I get a DraftKings API key?
You cannot. There is no individual API key program. The only way to get authenticated access is to become a B2B partner through DraftKings business development, which requires a registered company, regulatory standing, and a commercial agreement.
What is the DraftKings sportsbook API?
There is no public sportsbook API. Internal GraphQL endpoints power the DraftKings website and have been reverse-engineered on GitHub, but they are unstable and against the DraftKings Terms of Service.
How do I get DraftKings odds for my project?
Use a third-party odds aggregator. The Odds API has a free tier of 500 requests per month. OddsJam is the pro option starting around $300 per month. SportsRadar is the enterprise route for licensed media and operators.
Is there a DraftKings odds API I can use for free?
Not directly from DraftKings. The Odds API offers a free tier that includes DraftKings markets and gives you 500 requests per month, which is enough for personal projects and prototyping.
Can I use DraftKings data in a commercial product?
Only with a partnership agreement. Building on reverse-engineered endpoints exposes you to ToS violations and IP blocks. For commercial use, license through DraftKings business development or a contracted aggregator like SportsRadar.
