Getting Started¶
This guide walks through the most common workflows in under 5 minutes. No API keys needed for the first four steps — all public endpoints work out of the box.
Install¶
Create a client¶
No configuration needed for public endpoints. See Configuration for setting up API keys.
Search markets¶
# Active markets sorted by 24h volume
markets = client.get_markets(closed=False, order="volume24hr", ascending=False, limit=20)
print(markets[["slug", "question", "volume24hr", "endDate"]])
Every method returns a pd.DataFrame with parsed datetimes, numeric columns, and camelCase column names.
# Expand nested event and series data into prefixed columns
markets = client.get_markets(
closed=False,
expand_events=True,
expand_series=True,
limit=50,
)
# Autopaginate all results
all_politics = client.get_markets_all(closed=False, tag_id=15)
Get an orderbook¶
Extract a token ID from the markets DataFrame and query its orderbook:
token_id = markets["clobTokenIds"].iloc[0]
book = client.get_orderbook(token_id)
print(book[["price", "size", "side"]])
# Scalar helpers
spread = client.get_spread(token_id) # float
mid = client.get_midpoint_price(token_id) # float
Price history¶
prices = client.get_price_history(
market=token_id,
interval="1d",
fidelity=60, # resolution in minutes
)
# DataFrame with columns: timestamp (datetime), price (float)
prices.plot(x="timestamp", y="price", title="Price History")
Explore positions (requires auth)¶
Private endpoints need L2 API credentials. Set them via environment variables:
export POLYMARKET_ADDRESS=0xYourProxyWallet
export POLYMARKET_API_KEY=your-api-key
export POLYMARKET_API_SECRET=your-secret
export POLYMARKET_API_PASSPHRASE=your-passphrase
Or derive them from your private key:
client = PolymarketPandas(private_key="0xYourKey")
creds = client.derive_api_key() # auto-sets L2 credentials
Then query your portfolio:
