FAQ

How do I get live Washington Nationals scores in JSON?
Call GET https://www.realtimesportsapi.com/api/v1/sports/baseball/leagues/mlb/events/live with a free API key and keep the games where homeTeam.id or awayTeam.id is "20". The live endpoint returns the score, period, clock and status for games in progress. Data is aggregated from public sources and is typically 20-30 seconds behind live play (about 1 second after our source). There is no SLA.
Is there a free Washington Nationals API?
Yes. The Free plan of Realtime Sports API is $0 with 1,000 calls in the first 30 days, then 125 calls per month, no card. The same key covers every MLB team and the other leagues.
What is the Washington Nationals team id?
"20" in league "mlb" (sport "baseball"). Use it with /sports/baseball/leagues/mlb/teams/20 for team details and /sports/baseball/leagues/mlb/teams/20/roster for the roster, and to filter events by homeTeam.id or awayTeam.id.
What was the last Washington Nationals result?
New York Mets 4, Washington Nationals 6 on Sun, Sep 27. No upcoming games were listed when this page was generated.
Does the API include Washington Nationals betting odds?
Yes, for upcoming MLB games that have a line: GET /sports/baseball/leagues/mlb/events/{eventId}/odds returns the spread, moneyline and total from a single source book, and /odds/history returns line moves. It is not a multi-book comparison feed.
Can I get Washington Nationals score alerts pushed to me?
Yes, on paid plans: register a webhook for event.score_change and event.final filtered to league "mlb", then keep deliveries where data.homeTeam.id or data.awayTeam.id is "20" (webhooks filter by league, not team). WebSocket works the same way.
