How this service works
Detail of ONE prediction market or event by numeric id, 0x conditionId, market-slug or event-slug (auto-detected): normalized outcomes with implied probabilities, volume, liquidity, close date, status and a link-back.
Output
Returns a normalized object for the requested prediction market including: list of outcomes with implied probabilities (%), total trading volume, available liquidity, market close/expiry date, current status (open/closed/resolved), venue, and a link-back URL to the market. Auto-detects whether the supplied ID is a numeric market ID, 0x condition ID, market slug, or event slug.
Example use cases
Check election outcome odds
“Look up the Polymarket market with slug 'us-presidential-election-winner-2024' and tell me the current implied probability for each candidate, plus the trading volume and close date.”
Monitor a market by condition ID
“Fetch the details for Polymarket condition ID 0x3a4b2c1d... — I need the current outcome probabilities, liquidity, and whether the market is still open or resolved.”
Research event probability for a report
“I'm writing a research note — can you pull the Polymarket market for 'will-btc-hit-100k-by-eoy' and give me all the outcome probabilities, volume, and the market close date?”

Endpoint
GEThttps://api.agentstools.dev/prediction/market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed, normalized data for a single specific prediction market — including probabilities, liquidity, volume, and status — identified by any of its common identifiers (numeric ID, condition ID, or slug). Prefer this over search endpoints when you already know the market identifier. Best for agents that need to quote current odds, monitor a specific market, or enrich reporting with live prediction market data.
Side effects
- Invalid or unknown market ID/slug returns a 404 or empty result
- Ambiguous ID type that cannot be auto-detected may require the id_type hint parameter
- Market data may be stale if Polymarket API is delayed
- Non-Polymarket venues not yet supported (only 'polymarket' accepted for venue)
- Malformed 0x condition ID format returns a validation error
