The smallest useful Jev request.

1. Send state and questions

Put the facts relevant to the decision in state. Each entry in questions has a stable key, a supported type, instructions, and type-specific criteria when needed.

curl https://api.typesafe.ai/v1/systemone \
  -H "Authorization: Bearer $JEV_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "jev-latest",
    "state": "A customer reports two posted charges for one order.",
    "questions": {
      "queue": {
        "type": "choice",
        "instructions": "Which team should handle this?",
        "criteria": {
          "billing": "Payments, refunds, and invoices",
          "technical": "Product bugs"
        }
      }
    }
  }'

2. Keep the output typed

Do not turn the result back into an open-ended chat response unless your product actually needs prose. The useful part of Jev is that your code can act on a known answer shape and inspect uncertainty.

3. Apply your own policy

Jev supplies a judgment. Your application remains responsible for authorization, thresholds, human review, and any external side effect.
