SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Manually querying Polymarket's fragmented public APIs and parsing their double-encoded JSON response fields is time-consuming and error-prone for users needing quick access to prediction market data.

  • Automated Data Parsing: Automatically handles double-encoded JSON fields like outcomePrices and clobTokenIds, formatting probability prices as human-readable percentages with associated volume data.
  • Use Case Example: A security analyst can quickly check prediction market odds for a geopolitical event to inform threat intelligence assessments, or a researcher can track probability shifts for a scientific outcome over time without writing custom API code.

Quick Start
