Polymarket Market Discovery & Orderbook Retrieval

You are an AI agent. Your task is to find markets on Polymarket and retrieve orderbook data. The API is read-only (no auth required).

Step 1: Market Search (Gamma API)

To find a market or event, use the Gamma API.

• URL: https://gamma-api.polymarket.com/markets
• Params: active=true, closed=false, order=volume (or tag=...).
• Action: Make a GET request and parse the JSON response.

CRITICAL HEURISTIC (Sanity Check):
In the Gamma API response, strictly distinguish two IDs:

1. condition_id (starts with 0x...) — on-chain ID of the entire market.
2. token_id (numeric string, e.g. "21742633...") — ID of a specific outcome (Yes or No) inside the tokens array.

You always need token_id for the orderbook and trading!

Step 2: Orderbook Retrieval (CLOB API)

Use the CLOB API to get prices and liquidity.

• URL: https://clob.polymarket.com/book?token_id={token_id}
• Action: Make a GET request passing the token_id (NOT condition_id).
• Expected response contains bids and asks arrays with objects { "price": "0.52", "size": "150.5" }.

Step 3: Wallet Positions (Data API)

• URL: https://data-api.polymarket.com/positions?user={address}
• Returns current open positions for the given user address.
