How this service works
All active MLB baseball markets with live probabilities in one call — One-call board of the most active MLB baseball prediction markets: top markets by volume with blended live probabilities, resolution dates, and per-market slugs for drill-down. The bulk read for agents tracking the state of MLB baseball at a glance.
Output
Returns a JSON object with a 'data' field containing the category label ('MLB') and an array of market objects, each with a slug (for drill-down), a question string, a blended live probability (0–1), 24-hour USD volume, and a resolution date string. A 'meta' object is also included at the top level.
Example use cases
Live MLB game outcome monitoring
“Give me a snapshot of all active MLB baseball prediction markets right now — I want to see the live probabilities and which markets have the most trading volume today.”
Daily sports briefing for fantasy analysts
“Pull the top 20 MLB baseball prediction markets with their current probabilities and resolution dates so I can build my daily fantasy lineup around the most likely outcomes.”
Automated market-state tracking agent
“Fetch the full MLB prediction market board — all 50 markets if available — so I can log current probabilities and check back later to see what's shifted.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/board/sports-mlbWhen to prefer
Use this endpoint when you need a broad, single-call snapshot of the entire active MLB baseball prediction market landscape — especially for bulk reads, daily briefings, or initializing a monitoring agent. Prefer this over drill-down slug endpoints when you don't yet know which specific markets exist or want ranked-by-volume ordering. Choose this over NBA or other sports endpoints when the user's focus is specifically on Major League Baseball.
Side effects
- Invalid 'limit' parameter outside 1-50 range returns a validation error
- Payment failure or insufficient USDC balance returns HTTP 402
- Network timeout if downstream prediction market data source is slow
- Empty markets array if no MLB markets are currently active
- Rate limiting if called too frequently without payment
