How to Look Up IDs

Most endpoints require an ID that comes from the /markets response. Always query markets first, then pass the relevant ID to downstream endpoints.

1. Polymarket token_id: Query /polymarket/markets, find side_a.id or side_b.id in the response, then pass it to /polymarket/market-price/{token_id}.
2. Polymarket condition_id: Query /polymarket/markets, find condition_id in the response, then pass it to /polymarket/candlesticks/{condition_id}.
3. Kalshi market_ticker: Query /kalshi/markets, find market_ticker in the response, then pass it to /kalshi/market-price/{market_ticker}.

End-to-End Examples

Get the current price of a Polymarket market

Prices require a token_id, which comes from the /markets response. Always query markets first.

Step 1: Find a market and extract the token_id:

# Search for open election markets and grab a token_id
python scripts/prediction_market_client.py polymarket markets --search "election" --status open --limit 5

The response includes a side_a.id and side_b.id for each market; these are the token IDs for the Yes and No sides respectively:

{
  "markets": [
    {
      "title": "Will Trump nationalize elections?",
      "market_slug": "will-trump-nationalize-elections",
      "condition_id": "0xe6522d64f35a6843ebdbccab2e3d4a1385350be6d40a3de766330e207b71a8ba",
      "side_a": {
        "id": "44482086252598348208660011972852804909957485351743405768768577675743702971026",
        "label": "Yes"
      },
      "side_b": {
        "id": "68987475491741167427045844503509447338405188188495224371188027929166363674438",
        "label": "No"
      }
    }
  ]
}

Step 2: Fetch the current price using the token_id:

# Use side_a.id (Yes) or side_b.id (No) from Step 1
python scripts/prediction_market_client.py polymarket price 44482086252598348208660011972852804909957485351743405768768577675743702971026

The price is a decimal between 0 and 1 representing the probability (e.g. 0.20 = 20% chance of Yes).
