There's no public DraftKings API.
We solved that for you.

Sample request — DraftKings + cross-book in one call

Same response shape the-odds-api uses. The bookmakers[].markets[].outcomes[] nesting is unchanged, so any code that consumes the-odds-api works after a base-URL swap. To filter to DraftKings only, add &bookmakers=draftkings.

What you get on top of DraftKings odds

If you only need raw DK lines, our free tier covers it. The Hobby tier ($9/mo) extends the same DK data with the moat features the-odds-api doesn't ship.
