Typical uses are routing, classification, policy checks and any decision that needs a fast, scored answer.

Send POST /v1/alpha/decisions to Hormouz with your API key, a state and a set of typed questions. The response shape is the same as the upstream decisions API, so existing code works by changing the base URL.

Structured decisions

D1 is Liquid AI's structured decision model. You send a state and typed questions, and for each question it returns a choice, a score or a yes/no answer with a probability taken directly from the model rather than written out as text. It uses the same request shape as the other decision models, so you can switch between them without rewriting code. It reads up to 66K tokens of state per request.

Through Hormouz it is reached at POST /v1/alpha/decisions with your ordinary API key. The request carries a state and the questions, and the reply comes back typed, so your code branches on the numbers instead of parsing a sentence. You pay only for input, at $0.04 per million tokens; the answer itself is free. There is no fixed monthly fee.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
