Jev Decisions API

Call POST https://api.funcd.org/v1/decisions with your FUNCD API key. Use jev-1.13 for a pinned version or jev-latest for the latest Jev release. Jev returns typed judgments, not chat text; Chat Completions, Messages, and streaming are not supported.

bash

curl 'https://api.funcd.org/v1/decisions' \
  -H "Authorization: Bearer $FUNCD_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "jev-1.13",
    "state": {"ticket": "The login page is broken"},
    "questions": {
      "is_bug": {"type": "noul", "instructions": "Is the user reporting a software defect?"}
    }
  }'

state accepts a string, object, or array. Submit 1–16 questions: noul returns a probability; choice requires a criteria option object; score requires an ordered criteria array.

The same model permissions, key expiry, budget, and wallet apply. FUNCD reserves a full context per question, then charges reported token usage at the published rate and releases the remainder. Uncertain requests remain pending reconciliation.

The September 20, 2026 published snapshot charges $0.0462 per million input tokens with free output. See the model catalog. The latest alias follows model versions; it does not automatically change published prices.
