What is Polymarket Prediction Market Data?
This Openclaw Skills extension enables users to interface with the Polymarket public API without requiring authentication. It provides programmatic access to market trends, specific event outcomes, and trading volumes, making it an essential tool for developers and analysts tracking real-world event probabilities via decentralized prediction markets.
By leveraging this tool, users can integrate real-time sentiment and probability data into their AI agents or research pipelines. The skill simplifies the process of interpreting complex order book data into human-readable percentages and liquidity signals.
Polymarket Prediction Market Data Use Cases
- Monitoring real-time betting odds for political, economic, or entertainment events.
- Researching high-volume prediction markets to gauge public sentiment and crowdsourced truth.
- Fetching market-specific data using slugs for deep-dive financial analysis.
- Comparing outcome prices to calculate event probabilities in automated reporting workflows.
How Polymarket Prediction Market Data Works
- The user invokes the script located in the polymarket skill directory with specific flags.
- The skill sends a request to the Polymarket Gamma API endpoints, targeting either individual markets or grouped events.
- The API returns raw JSON data containing outcome prices, market questions, and volume metrics.
- The script processes the outcomePrices (0-1) into percentage probabilities and formats the output for the user.
Polymarket Prediction Market Data Setup
To use this within your environment, ensure Python 3 is installed and navigate to the skill script location. No API keys are required for public data access.
