Now that create order is on the yes-side, creating an ask yes at (1-price) is the same as bid no at price. https://docs.kalshi.com/api-reference/orders/create-order-v2

An ask at 1- price is selling a yes at 1-price, a bid at price is buying yes at price. I wish to buy nos. Is there an additional parameter?

No. A 90c ask for "yes" and a 10c bid for "no" are exactly the same order. https://docs.kalshi.com/getting_started/order_direction

changing "outcome_side" does not change only being able to by/sell yes order. For events with more than two markets, a no is fundamentally different than a yes

There has never been any such thing as a no contract to buy. It's always been strictly a construct of the UI. You have a positive or negative position on the single order book. Buying increases your position by placing bids, selling reduces your position by placing asks

So a position of -100 is the same as "owning 100 no contracts" in the UI

You place an an order on the ask side. This sells a position on the yes order book. That's the same as a no

It's exactly what the UI is doing when you "buy no" it just isn't dressing it up for you

The order book will absolutely never show buy no. The UI is a mirage. It is skinned for casual users

Everything on the api is based on a single "yes" order book. A positive outcome on given strike
