ParlayAPI mirrors the-odds-api's v4 REST shape for MLB data: same
baseball_mlb sport key, same paths, same query parameters,
same response JSON. Swap the base URL and your existing code keeps working.

# before curl "https://api.the-odds-api.com/v4/sports/baseball_mlb/odds?regions=us&markets=h2h,spreads,totals&apiKey=YOUR_TOA_KEY" # after curl "https://parlay-api.com/v4/sports/baseball_mlb/odds?regions=us&markets=h2h,spreads,totals&apiKey=YOUR_PARLAY_KEY"
the-odds-api is older, simpler, and more battle-tested, with a much larger base of tutorials, Stack Overflow answers, and community wrappers to copy from. If your MLB needs are basic - one region, game lines only, no streaming - its smaller surface area is a genuine advantage. Our honest roundup of the-odds-api alternatives compares seven providers side by side, us included.
Endpoint shapes below are the real ones from the API docs.
Auth is either the-odds-api-style apiKey= query param or an
X-API-Key header.

Yes. ParlayAPI's free tier includes 1,000 credits per month with no credit
card required, and it covers MLB game lines the same as paid plans. One call to
/v1/sports/baseball_mlb/odds returns moneyline, run line
(spread), and total prices. Current paid tiers are listed at

Yes, and MLB is the deepest sport on the board right now.
GET /v1/sports/baseball_mlb/props returns MLB player props -
hits, total bases, home runs, RBIs, runs and more - on canonical market keys
(player_hits, player_total_bases,
player_home_runs, player_rbis). Measured in the
last 24 hours (2026-08), 40 sources wrote over 3 million MLB prop rows
across 2,800+ distinct market keys.
Yes. The archive holds 111,000+ MLB closing game lines back to 2010,
inside a platform archive of 1.7M+ closing game lines with continuous
coverage back to 2005, plus 30M+ prop closing lines since June 2022. Query
/v1/historical/sports/baseball_mlb/odds for snapshots or
/v1/historical/sports/baseball_mlb/closing-odds for closing
lines - useful for CLV tracking and model backtests.
Yes - ParlayAPI mirrors the-odds-api's v4 REST shape: the same
baseball_mlb sport key, the same endpoint paths, the same
query parameters, and the same JSON response shape. Migrating an existing
integration is a base-URL change from api.the-odds-api.com/v4 to
parlay-api.com/v4 - see the
migration guide. To be fair,
the-odds-api is older and simpler with a larger base of tutorials; if you
don't need props depth, streaming, or prediction-market signals, it remains a
solid choice.
Yes. REST polling is available on every tier, with sub-5-second freshness
on major books. Business tier and above adds WebSocket streaming at
/ws/odds/baseball_mlb, which pushes line movement to you
instead of making you poll. Platform-wide we process 100k+ game-line updates
per hour and roughly half a million prop updates per hour. You can watch the
live board at /live before signing up.
The pennant race is on and the postseason opens September 29. Sign up free - 1,000 credits a month, no card required - and have MLB lines flowing in minutes.
