Decision API: One API Endpoint for Decision AI Models

Decision API is a decision AI aggregation platform that brings decision models from top AI labs into one API for classification, scoring, and routing. The platform unifies decision models hosted on OpenRouter - including Jev 1.13, Kev 4B, Liquid d1, Solar Decide, Laya, and Span-01 - behind a single OpenAI-compatible endpoint at decisionapi.org. Developers send structured, typed questions with options and weights, and receive typed responses with scores, selected options, and confidence values. Beyond the raw API, Decision API ships with a browser playground for comparing models side by side, plus a workbench for saving and refining configurations. The API key dashboard includes usage tracking, and credit packs start at $10 for 100,000 credits, with 100 free credits for new accounts. Full details are on the Pricing page. For teams building agents, routers, or review workflows, a dedicated decision layer keeps the main LLM focused on generation while decision models handle the structured choice.
