Jev API
Structured AI decisions with probabilities, not prose
Jev API turns a state plus typed questions into structured choice, score, and yes/no decisions with probabilities. Use one System One-compatible endpoint, versioned model IDs, prepaid usage, and a public Agent Skill your own agent can install from a link. Built for automation workflows that need machine-readable answers instead of free-form chat.

Hi Product Hunt — I built Jev API because many automation tasks need a bounded decision, not another paragraph. Send one state plus typed questions (choice, score, or yes/no) and get structured answers with probabilities and token usage. The API follows the System One contract, supports latest, preview, and pinned model versions, and includes a public Agent Skill that any agent can install from a link. I’d love feedback on the API shape, the Agent Skill onboarding, and the decision use cases you would try first.
