Store credentials as environment variables:
POLYMARKET_KEY_ID β API key UUIDPOLYMARKET_SECRET_KEY β Ed25519 private key (base64)Usage
Write and execute Python scripts using the polymarket_us SDK. For full API details, read references/api_reference.md.
Public Data (no auth)
from polymarket_us import PolymarketUS
client = PolymarketUS()Search markets
results = client.search.query({"query": "bitcoin", "limit": 5})Browse trending markets
markets = client.markets.list({"limit": 10, "orderBy": ["volumeNum"], "orderDirection": "desc"})Check price
bbo = client.markets.bbo("market-slug")client.close()

import os
from polymarket_us import PolymarketUSclient = PolymarketUS(
key_id=os.environ["POLYMARKET_KEY_ID"],
secret_key=os.environ["POLYMARKET_SECRET_KEY"],
)
Check balance
balances = client.account.balances()View positions
positions = client.portfolio.positions()Preview then place order
preview = client.orders.preview({"request": {
"marketSlug": "some-market",
"intent": "ORDER_INTENT_BUY_LONG",
"type": "ORDER_TYPE_LIMIT",
"price": {"value": "0.55", "currency": "USD"},
"quantity": 100,
}})Place order (ALWAYS confirm with user before executing)
order = client.orders.create({
"marketSlug": "some-market",
"intent": "ORDER_INTENT_BUY_LONG",
"type": "ORDER_TYPE_LIMIT",
"price": {"value": "0.55", "currency": "USD"},
"quantity": 100,
"tif": "TIME_IN_FORCE_GOOD_TILL_CANCEL",
})client.close()
Key Rules
1. Always preview orders before placing β show the user what they're about to trade
2. Always confirm with the user before placing any order β never auto-trade
3. Price is always the YES side β to buy NO at $0.40, set price to $0.60 (1.00 - 0.40)
4. In market slugs: first team = YES, second team = NO
5. Valid price range: 0.001 to 0.999
6. Handle errors gracefully β catch AuthenticationError, BadRequestError, RateLimitError, etc.
