# JEV SystemOne

JEV SystemOne

## Endpoint and authentication

`POST https://api.tu-zi.com/v1/systemone`

Transport: json

Use an inference API key. Examples contain placeholders; read credentials from environment variables.

```http
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
```

## Body parameters

| Field | Type | Required | Description / constraints |
| --- | --- | --- | --- |
| model | string | Yes | JEV model identifier, for example jev-1.13. Example: jev-1.13 |
| state | string \| object | Yes | Business state as text or a JSON object, such as ticket, order or alert context. Example: 请判断这条工单是否紧急 |
| questions | object | Yes | A nonempty JSON object defining questions: noul uses instructions; choice uses a criteria object; score uses a criteria array. Example: {"urgency":{"type":"choice","criteria":{"p0":"立即处理","p1":"尽快处理"},"instructions":"判断紧急等级"}} |

## Minimal request example

```json
{
  "model": "YOUR_MODEL",
  "state": "A support ticket",
  "questions": {
    "urgent": {
      "type": "choice",
      "criteria": {
        "yes": "Urgent",
        "no": "Not urgent"
      }
    }
  }
}
```

## Before running

Replace https://api.tu-zi.com with this site origin (do not append /v1 twice), and YOUR_MODEL with the exact marketplace model ID. Install requests for Python; use Node.js 20+ and save JavaScript as .mjs. WebSocket samples list their own dependencies.

Create an inference key on the site and set API_KEY in the environment; replace YOUR_API_KEY in cURL. Prepare local input.png/input.wav files for upload examples.

Start with a minimal request, then read the result using the response fields below. For async APIs, a returned task ID requires polling; acceptance does not mean generation has finished.

## Code examples

### curl

```bash
curl --request POST 'https://api.tu-zi.com/v1/systemone' \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
  "model": "YOUR_MODEL",
  "state": "A support ticket",
  "questions": {
    "urgent": {
      "type": "choice",
      "criteria": {
        "yes": "Urgent",
        "no": "Not urgent"
      }
    }
  }
}'
```

### python

```python
import json
import os
import requests

url = "https://api.tu-zi.com/v1/systemone"
headers = json.loads("{\"Authorization\":\"Bearer YOUR_API_KEY\",\"Content-Type\":\"application/json\"}")
headers["Authorization"] = "Bearer " + os.environ["API_KEY"]
payload = json.loads("{\"model\":\"YOUR_MODEL\",\"state\":\"A support ticket\",\"questions\":{\"urgent\":{\"type\":\"choice\",\"criteria\":{\"yes\":\"Urgent\",\"no\":\"Not urgent\"}}}}")
response = requests.request("POST", url, headers=headers, json=payload, timeout=120)
response.raise_for_status()
result = response.json()
if isinstance(result, dict) and (result.get("success") is False or result.get("error")):
    raise RuntimeError(json.dumps(result, ensure_ascii=False))
print(result)  # Also inspect protocol-specific status/code fields.
```

### javascript

```javascript
// Node.js 20+
const url = "https://api.tu-zi.com/v1/systemone";
const headers = {
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
};
headers.Authorization = 'Bearer ' + process.env.API_KEY;
const response = await fetch(url, { method: "POST", headers, body: JSON.stringify({
  "model": "YOUR_MODEL",
  "state": "A support ticket",
  "questions": {
    "urgent": {
      "type": "choice",
      "criteria": {
        "yes": "Urgent",
        "no": "Not urgent"
      }
    }
  }
}) });
if (!response.ok) throw new Error(await response.text());
const result = await response.json();
if (result?.success === false || result?.error) throw new Error(JSON.stringify(result));
console.log(result); // Also inspect protocol-specific status/code fields.
```

## Response fields

| Field | Type | Description / constraints |
| --- | --- | --- |
| answers | object | Native answer object; Community may wrap it in data.answers. |
| usage | object | Usage when supplied by the provider. |

Illustrative response; some endpoints show essential fields only. Optional fields may be absent.

```json
{
  "answers": {
    "urgent": {
      "choice": "yes"
    }
  }
}
```

## Errors and retries

Check HTTP status and protocol-specific errors; do not mix error formats across protocols. For 401/403 check credentials and permissions, for 429 back off, and for 5xx check gateway/upstream status. Error bodies may contain error/message/code depending on the protocol.

Use bounded exponential backoff for reads. Do not blindly retry task creation, generation, or key mutations, to avoid duplicate billing or execution.

## Constraints

This page describes the base protocol. Use the selected model quick start for supported fields, enums, limits and asynchronous behavior. Replace YOUR_MODEL. Form initial values are not upstream defaults.
