How this service works
Market structure metadata: type detection, available outcomes with probabilities
Output
Returns structured metadata about the specified prediction market, including the detected market type (e.g. binary, categorical, scalar), a list of all available outcomes, and the current probability assigned to each outcome.
Example use cases
Compare prediction market outcome odds
“I'm looking at several crypto prediction markets right now. Can you check the structure and current probabilities for each one so I can see which outcomes are most likely?”
Verify market type before placing trade
“Before I trade on this Polymarket, I need to know what kind of market it is and what all the possible outcomes are. Can you pull that information for me?”
Analyze scalar market odds distribution
“Show me the structure of this prediction market along with all available outcomes and their probabilities so I can understand how the odds are currently distributed.”
Technical details
Endpoint
POSThttps://polynews.news/api/v1/market-infoWhen to prefer
Use this endpoint when you need to understand the structure of a specific prediction market before trading, analyzing, or comparing it — especially when you need to know which outcome types are available and their current odds. Prefer this over broader market-context or smart-money endpoints when you only need structural metadata without news or wallet analysis.
Side effects
- Market identifier not found or invalid — returns 404 or empty result
- Market has been resolved or delisted — may return stale or unavailable data
- Ambiguous market slug matches multiple markets — may require more specific identifier
- Rate limiting or payment failure — returns 402 or 429 error
- Network timeout for real-time probability fetch
