What problem does it solve?

This Skill helps you programmatically place, cancel, and manage orders on Polymarket’s prediction markets without manually interacting with the UI.

Core Features & Use Cases

  • Two-level authentication: uses wallet signature (L1) to create/derive API keys, then uses HMAC credentials (L2) for trading operations.
  • Order creation for limit and market trading: supports limit orders plus market orders with FOK/FAK execution styles.
  • Market data + account management: fetches order books, markets, tickers, trades, balances, and positions for strategy automation.
  • Use Case: build a simple market-making bot that periodically reads the best bid/ask, calculates spread, cancels stale orders, and re-quotes around the mid price.

Quick Start

Use the polymarket-clob-client to create an authenticated client, then call createAndPostOrder to place a limit BUY order on the Polymarket CLOB for a specific tokenID.
