Decisions API

Decisions API is a developer platform that gives one API and playground for more than 35 structured decision models from providers such as TypeSafe, Liquid AI, Perplexity, Nace.AI and OpenAI's GPT-6 Luna Decisions. It is built for developers who need to classify, score or route text and images inside their own applications.

A request sends shared state (text, JSON or up to four images) along with one or more typed questions, each returning a choice, a numeric score, or a Noul yes/no probability, with confidence attached to every answer. Developers can preview a task in the browser playground, tune the questions, then call the same configuration from their own server with a Bearer token.

All usage, across the playground, the API, and evaluation runs, draws from one shared credit balance at the same per-model rate; a budget is reserved before each call and the difference is refunded after the actual input tokens are counted. New accounts receive 100 credits to try the service, and a dataset tool lets a team capture two different model or rule configurations and compare them against up to 25 labeled cases.

Pricing is a one-time credit purchase rather than a subscription: $1 buys 10,000 credits on every pack, starting with a $10 Starter pack and rising to $100 Pro and $1,000 Volume packs, all with no expiry. Model rates vary by provider, from roughly $0.01 per million input tokens for the cheapest model up to $0.35 for the most expensive, and output tokens are not charged.
