How this service works
Biggest MLB baseball probability moves (1h/6h/24h) — The fastest way to see where news is landing in MLB baseball: active markets ranked by absolute probability change over your chosen window, with volume surge ratios. Same shape as /v1/movers, pre-filtered to MLB baseball markets.
Output
An array of MLB baseball prediction market movers, each including the market slug, the question text, current probability (p_now), previous probability (p_prev), absolute probability delta, volume surge ratio, and category — sorted by largest absolute probability change over the selected window. Also includes a meta object with request context.
Example use cases
Breaking news impact on baseball markets
“What are the top 20 MLB baseball prediction markets moving the most in the last hour? I want to see where breaking news is hitting hardest.”
Daily pregame market scouting
“Pull up the biggest probability shifts in MLB baseball markets over the last 24 hours — top 15 results — so I can see which games or outcomes have moved the most today.”
High-liquidity baseball movers filter
“Show me the top 10 MLB baseball markets moving the most over the past 6 hours, but only include markets with a liquidity score of at least 0.5.”
