noul

Get the probability that a condition is true, such as whether a ticket is urgent.

Choose a category

choice

Route to an allowed team or label, with a probability for each option.

Score on a scale

score

Define ordered levels and read a probability-weighted score, starting at zero.

Use Clef with your Jev AI API key

Create an API key and store it as JEV_AI_API_KEY on your server. Check authenticated GET /api/v1/models for configured models before sending requests.

curl --fail-with-body https://jev-ai.pro/api/v1/systemone \
  -H "Authorization: Bearer $JEV_AI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "clef",
  "state": "Checkout has failed for every customer for the last hour.",
  "questions": {
    "urgent": {
      "type": "noul",
      "instructions": "Does this incident need immediate attention?"
    },
    "team": {
      "type": "choice",
      "instructions": "Which team should handle this incident?",
      "criteria": {
        "billing": "Payments, invoices and refunds",
        "technical": "Outages, errors and configuration"
      }
    },
    "severity": {
      "type": "score",
      "instructions": "How severe is the customer impact?",
      "criteria": [
        "Minor",
        "Major",
        "Critical"
      ]
    }
  }
}'

The response contains model, answers and usage. Read answers.urgent.noul, answers.team.probabilities and answers.severity.score for this example. Saved judges also work with either model.

What is available through Jev AI?

This integration accepts text, JSON objects and arrays. The playground allows up to 8,000 state characters and eight questions; the API allows up to 64 questions in a 256,000-byte request. Question and option limits still apply.

Cloudflare documents a 65,536-token model context window and embedded-image support. Images are not enabled through this Jev AI integration. Cloudflare may truncate long text to fit the model context, so keep each request focused and split large documents before sending.

Playground runs use the existing one-credit billing flow. API runs use paid input tokens first, with the existing whole-request credit fallback. Failed calls do not consume your reserved balance. See your Jev AI pricing.

Clef runs on Cloudflare Workers AI. A Clef request stays on the selected model; an unavailable Clef model returns an error instead of switching to Jev.

About the models

Clef and Clef Flash are Cloudflare decision models with Apache 2.0 weights. Jev AI provides an independent playground and API integration; it is not Cloudflare's official product site.
