### Inference in Germany.

Your request goes straight to our Hetzner server in Germany and is answered there. No proxy, CDN, or external model API sits in between.

Turn context into choices, probabilities, and scores.

Run your question to see the answer.

Prompts and answers are processed in Germany and are not stored. A data processing agreement and subprocessor list are one click away.

Classify text, compare options, and return structured decisions through one API.

Use your eu/jev API key and base URL, and set the model to jeff-latest. Check the supported request fields and limits below.

``` js
const response = await fetch("https://jev.bevel.software/v1/systemone", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    model: "jeff-latest",
    state: "I was charged twice. Can I get a refund?",
    questions: {
      team: {
        type: "choice",
        instructions: "Which team should handle this?",
        criteria: {
          billing: "Payments, invoices, and refunds",
          support: "Technical issues and bugs"
        }
      }
    }
  })
});

if (!response.ok) throw new Error(await response.text());
const { answers } = await response.json();
console.log(answers.team.choice); // "billing"
```
