Does Robinhood have a sports betting API?
How Robinhood's sports event contracts work, why there is no public Robinhood odds API, and how to read those prices programmatically.
Robinhood offers sports event contracts through its partnership with Kalshi, and it publishes no public API for reading those markets. The programmatic route is the underlying exchange data: Robinhood Event Contracts is a Kalshi white label carrying the same prices, so ParlayAPI's prediction-market endpoints filtered with ?sources=kalshi return the prices Robinhood users trade, and the odds and props endpoints accept ?bookmakers=robinhood as an alias for the same surface.
More detail
Event contract prices are quoted in cents and map directly to implied probability: a 62 cent contract implies 62 percent. ParlayAPI keeps them source-native and labeled rather than converting them into synthetic moneylines, so comparisons against sportsbook odds stay deliberate.
The comparison workflow: pull GET /v1/prediction-markets/{sport_key} for the exchange side and GET /v1/sports/{sport_key}/consensus for the no-vig sportsbook side, then compare in probability space. Where the exchange and the books disagree on the same game, that gap is a research candidate, not an asserted arbitrage, because settlement rules differ across venues.
Trading still happens on Robinhood or Kalshi themselves; ParlayAPI is read-only for research and comparison. For markets beyond scheduled games, GET /v1/event-markets/search finds contracts by free text with a volume filter to keep illiquid markets out of your results.
Endpoint
GET /v1/prediction-markets/{sport_key}
curl 'https://parlay-api.com/v1/prediction-markets/americanfootball_nfl?sources=kalshi' -H 'X-API-Key: YOUR_KEY'
Why developers use it
- Robinhood Event Contracts readable via the kalshi source
- Source-native cent prices, never fake moneylines
- Consensus endpoint for probability-space comparison
FAQ
Are Robinhood's prices different from Kalshi's?
They ride the same underlying exchange, so the prices match. ParlayAPI stores the data under the kalshi source: filter with ?sources=kalshi on the prediction-market endpoints, and ?bookmakers=robinhood works as an alias on the odds and props endpoints.
Can I place trades through ParlayAPI?
No. ParlayAPI reads and normalizes prices for comparison and research. Order placement belongs on Robinhood's app or Kalshi's own trading API.
How do I compare event contract prices to sportsbook odds?
Convert the contract price to implied probability and compare it against the devigged sportsbook consensus from GET /v1/sports/{sport_key}/consensus. Compare probabilities, never raw prices across venue formats.
