How this service works
Full detail for ONE Polymarket prediction market by id or slug — question, description, every outcome with its current price (implied probability), volume, liquidity, open/close dates, resolution source, category, and status. No API key. The drill-in companion to /prediction/markets (browse/search): find a market there, then pull its full state here. Pass id or slug as query (GET) or a JSON body (POST).
Output
Returns a JSON object with the market's question, description, category, all outcome names with their current implied probability prices (0–1 scale), lifetime volume in USD, 24h volume, liquidity in USD, start and end dates, active/closed status, resolution source, Polymarket URL, slug, and a cache_age_seconds field indicating data freshness (cached up to 60 seconds).
Example use cases
Track odds on a political event
“What are the current Yes and No prices on the Polymarket market for whether Trump will be reelected? Give me the slug 'will-donald-trump-win-the-2028-presidential-election' — I want the implied probabilities, 24h volume, and the closing date.”
Check market resolution criteria
“I found a Polymarket market with ID 665374 — can you pull its full details so I can read the exact resolution criteria and see who the resolution source is?”
Monitor liquidity before trading
“Before I trade on Polymarket, can you fetch the full state of the market 'will-the-fed-cut-rates-in-2025' — especially the current liquidity, 24h volume, and whether it's still active?”
Technical details
Endpoint
GEThttps://netintel.dev/prediction/marketWhen to prefer
Use this endpoint when you already have a specific Polymarket market identifier (ID or slug) and need its full current state — prices, volume, liquidity, and resolution details — in a single call. Prefer this over the /prediction/markets browse endpoint when you know which market you want. Ideal for agents that need real-time implied probabilities for a known event, or that want to read resolution criteria before acting.
Side effects
- Market ID or slug not found — returns error or empty result
- Ambiguous input when both id and slug are provided (id wins)
- Full Polymarket URL passed as slug — service extracts slug automatically but may fail on malformed URLs
- Market may be closed (closed=true) while active=true — consumers must check both fields
- Cache up to 60 seconds old — real-time price-sensitive use cases may see stale probabilities
- Malformed query parameter causes 4xx error
