Get Seattle Mariners scores in code

The events endpoint returns the whole MLB scoreboard, so keep the games where either team id is 12.

curl -H "Authorization: Bearer $RSA_API_KEY" \
  "https://www.realtimesportsapi.com/api/v1/sports/baseball/leagues/mlb/teams/12"

# This team's games in the current scoreboard (filter by team id 12)
curl -s -H "Authorization: Bearer $RSA_API_KEY" "https://www.realtimesportsapi.com/api/v1/sports/baseball/leagues/mlb/events" \
  | jq '.data[] | select(.homeTeam.id == "12" or .awayTeam.id == "12") | {name, date, status: .status.detail, home: .homeTeam.score, away: .awayTeam.score}'

const TEAM_ID = "12"; // Seattle Mariners
const res = await fetch("https://www.realtimesportsapi.com/api/v1/sports/baseball/leagues/mlb/events", {
  headers: { Authorization: `Bearer ${process.env.RSA_API_KEY}` }
});
const { data } = await res.json();
const games = data.filter((e) => e.homeTeam.id === TEAM_ID || e.awayTeam.id === TEAM_ID);
for (const g of games) {
  console.log(g.shortName, g.status.detail, `${g.awayTeam.score}-${g.homeTeam.score}`);
}

import os, requests

TEAM_ID = "12"  # Seattle Mariners
res = requests.get(

    headers={"Authorization": f"Bearer {os.environ['RSA_API_KEY']}"},
    timeout=10,

Using the Realtime Sports MCP server (https://www.realtimesportsapi.com/api/mcp), call get_schedule with sport "baseball" and league "mlb" for the next 14 days and list the Seattle Mariners games (team id 12) with dates and opponents; then call get_live_events and tell me if they are playing now.

More endpoints for this team: /sports/baseball/leagues/mlb/teams/12/roster, /sports/baseball/leagues/mlb/injuries?team=12, /sports/baseball/leagues/mlb/news?team=12. Step-by-step builds: guides.

FAQ

How do I get live Seattle Mariners 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 "12". 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 Seattle Mariners 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 Seattle Mariners team id?

"12" in league "mlb" (sport "baseball"). Use it with /sports/baseball/leagues/mlb/teams/12 for team details and /sports/baseball/leagues/mlb/teams/12/roster for the roster, and to filter events by homeTeam.id or awayTeam.id.

What was the last Seattle Mariners result?

Los Angeles Angels 3, Seattle Mariners 7 on Sun, Sep 27. No upcoming games were listed when this page was generated.

Does the API include Seattle Mariners 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 Seattle Mariners 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 "12" (webhooks filter by league, not team). WebSocket works the same way.
