# TypeSafe Jev 1.13

> Fast, inexpensive typed decisions for classification, routing, triage and guardrails.

TypeSafe Jev 1.13 is a System One decision model for fast, inexpensive classification, routing, triage, enum extraction and guardrail checks. Give it text or JSON state and named, typed questions: Choice selects one of your options, Noul returns a yes probability from 0 to 1, and Score returns an expected index over ordered levels (0 to N-1). It evaluates bounded decisions without generating prose or long reasoning, keeping latency and token cost low. Route a support ticket to billing/technical/sales, gate a workflow on refund eligibility, or label a lead hot/warm/cold. Answers include probabilities and, for Choice/Score, optional confidence. Use explicit criteria and review uncertain results. Text input only, 32K context; no free-form writing, arbitrary JSON-schema generation, code, media, explanations or long reasoning.

## Actions

- `decide(state, questions, request_id?)`: returns typed Choice, Noul or Score answers with upstream usage and the actual charge. For example, a ticket saying "charged twice" can select `billing` from `billing/technical/sales`.
- MCP clients can call `make_typed_decision` on either FlyMyAI MCP server.

## How to get credentials

This is a built-in FlyMyAI tool. Your FlyMyAI account pays for actual upstream input tokens; no personal OpenRouter API key is required.

## Fields to fill in FlyMyAI

None. Discover or enable **TypeSafe Jev 1.13** and supply text or JSON state and typed questions.

## Troubleshooting

402 means the balance cannot cover the maximum reservation. 409 means the request ID is already running or was reused with different input. A persistent 429, upstream failure or timeout does not charge. Use the same request ID to retrieve a completed result without paying twice.
