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.
