The simmer-sdk package wraps the REST API with an authenticated client and typed data classes. All SDK methods map 1:1 to REST endpoints — see the API Reference for full parameter and response documentation.
Installation
Initialization
from simmer_sdk import SimmerClient
# From env var (recommended)
# export SIMMER_API_KEY="sk_live_..."
client = SimmerClient()
# Or pass directly
client = SimmerClient(api_key="sk_live_...")
# With venue default
client = SimmerClient(venue="polymarket")
Quick example
# Find markets, check context, trade
markets = client.get_markets(q="bitcoin", limit=5)
context = client.get_market_context(markets[0].id)
if context.get("edge", {}).get("recommendation") == "TRADE":
result = client.trade(
market_id=markets[0].id,
side="yes",
amount=10.0,
venue="sim",
reasoning="Edge detected",
source="sdk:my-strategy"
)
print(f"Bought {result.shares_bought} shares for {result.cost}")
