Workflow

  1. Identify user intent: Determine what type of Polymarket data the user wants
  2. Select appropriate command: Choose the script command that best matches the query
  3. Execute the script: Run the Python script using execute_command tool
  4. Format the response: Present the results in a clear, readable format to the user in their language

Common Query Patterns

  • "Polymarket上有什么热门的？" → Use trending command
  • "X的赔率是多少？" → Use search to find the market, then odds or market with the market ID
  • "有什么体育比赛市场？" → Use sports command
  • "有哪些政治预测市场？" → Use politics command
  • "有什么正在进行的比赛？" → Use live command
  • "搜索比特币相关市场" → Use search --keyword "Bitcoin" command
  • "Polymarket有哪些分类？" → Use categories command
  • "今天NBA有什么比赛？" → Use schedule --sport nba --date YYYY-MM-DD command
  • "4月12日的足球比赛" → Use schedule --sport soccer --date 2026-04-12 command

Understanding Odds

Polymarket uses a price-based system where:

  • Price ranges from 0 to 1 (displayed as percentage, e.g., 65%)
  • A "Yes" price of 0.65 means the market thinks there's a 65% probability
  • Implied odds = 1 / price (e.g., 0.65 → 1.54x)
  • For multi-outcome markets (e.g., "Who will win X?"), each option has its own price

Direct API Fallback

If the script is unavailable or needs adjustment, query the Gamma API directly:

curl "https://gamma-api.polymarket.com/markets?limit=10&active=true&closed=false&order=volume24hr&ascending=false"
curl "https://gamma-api.polymarket.com/markets/{market_id}"
curl "https://gamma-api.polymarket.com/events/{event_id}"
curl "https://gamma-api.polymarket.com/categories"

For detailed API documentation, refer to references/api_reference.md.

Important Notes

  • Polymarket is a prediction market (not a traditional sportsbook). "Odds" represent probability estimates, not fixed payouts.
  • There is no "real-time score" feed in the Polymarket API — for live scores of sports events, consult sports-specific APIs. However, price movements on Polymarket often reflect game progress.
  • Market data is updated frequently but may have slight delays (typically seconds to minutes).
  • The Python script uses certifi for SSL certificate verification if available, otherwise tries system CA bundles. On Windows systems without certifi, it falls back to disabling cert verification with a warning. Install certifi (pip install certifi) for secure connections.
  • A PowerShell version is available in the GitHub repository for Windows users who prefer it.
  • Category slugs for direct filtering: sports, politics, crypto, business, coronavirus, pop-culture, science, ai
