How this service works
Get full detail (prices, volume, liquidity, resolution) for a single Polymarket market by slug
Output
A JSON object containing the market's question, slug, active/closed status, end date, outcome labels (e.g. Yes/No), current outcome prices (probabilities), liquidity in USD, 24-hour volume, 7-day volume, total volume, and a description of resolution criteria.
Example use cases
Track political event probability
“What are the current Yes and No prices on Polymarket for the market 'will-trump-win-2024'? I want to know the liquidity and 24-hour volume too.”
Check if a market has resolved
“Is the Polymarket market 'fed-rate-cut-march-2025' still active or has it closed and resolved? Can you get me the full details including end date and outcome prices?”
Research before placing a prediction
“Before I trade, pull the full detail on the Polymarket market 'us-recession-2025' — I need the current odds, total volume, and how much liquidity there is.”
Technical details
Endpoint
GEThttps://x402tap.com/api/polymarket-market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed, real-time data on a specific Polymarket prediction market by its slug — including precise outcome prices, liquidity depth, volume metrics, and resolution status. Prefer this over a market-list endpoint when you already know the market slug and need comprehensive single-market data. Choose this over generic web search when you need structured, machine-readable probability and trading data rather than articles or commentary.
Side effects
- Invalid or misspelled slug returns an error or empty response
- Market slug not found if the market has been delisted
- Stale data if Polymarket API is temporarily unavailable
- Rate limiting if many calls are made in quick succession
- Missing optional fields if market is newly created and has low activity
