Per-Outcome Orderbooks

YES and NO each have separate orderbooks. A BUY YES order only matches against SELL YES orders, never SELL NO.

When you specify outcome=YES, you get the YES orderbook:

• Bids: Users wanting to buy YES tokens

• Asks: Users wanting to sell YES tokens

Examples

# All orders (both YES and NO)
curl "https://api.turbinefi.com/api/v1/orderbook/0x1234...abcd"

# YES orderbook only
curl "https://api.turbinefi.com/api/v1/orderbook/0x1234...abcd?outcome=YES"

# NO orderbook only
curl "https://api.turbinefi.com/api/v1/orderbook/0x1234...abcd?outcome=NO"

If no orderbook exists for a market, an empty snapshot is returned with bids: [] and asks: [].
