# Retrieve account level limits

Retrieve account level limits within the current credential scope.

## Endpoint and authentication

`GET https://api.tu-zi.com/api/user/self/level_limits`

Transport: json

Use an account system token and New-Api-User (account ID), or a valid site login session. Manage system tokens in account settings. Inference API keys are not substitutes.

```http
Authorization: Bearer YOUR_SYSTEM_TOKEN
New-Api-User: YOUR_USER_ID
```

## Request parameters

No request body is needed; send the authentication described above.

## 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.

Set SYSTEM_TOKEN and USER_ID in the environment; keep system tokens out of frontend code. Replace YOUR_SYSTEM_TOKEN and YOUR_USER_ID in cURL.

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 GET 'https://api.tu-zi.com/api/user/self/level_limits' \
  --header 'Authorization: Bearer YOUR_SYSTEM_TOKEN' \
  --header 'New-Api-User: YOUR_USER_ID'
```

### python

```python
import json
import os
import requests

url = "https://api.tu-zi.com/api/user/self/level_limits"
headers = json.loads("{\"Authorization\":\"Bearer YOUR_SYSTEM_TOKEN\",\"New-Api-User\":\"YOUR_USER_ID\"}")
headers["Authorization"] = "Bearer " + os.environ["SYSTEM_TOKEN"]
headers["New-Api-User"] = os.environ["USER_ID"]
response = requests.request("GET", url, headers=headers, 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/api/user/self/level_limits";
const headers = {
  "Authorization": "Bearer YOUR_SYSTEM_TOKEN",
  "New-Api-User": "YOUR_USER_ID"
};
headers.Authorization = 'Bearer ' + process.env.SYSTEM_TOKEN;
headers['New-Api-User'] = process.env.USER_ID;
const response = await fetch(url, { method: "GET", headers });
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 |
| --- | --- | --- |
| success | boolean | Business success. |
| data.current_level | string | Current level. |
| data.tier | integer | Tier number. |
| data.levels | array | Level conditions and concurrency limits. |
| data.groups | string[] | Group IDs. |
| data.group_info | object | Group display information. |
| data.used_amount | number | Consumed amount. |
| data.recharge_amount | number | Recharged amount. |

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

```json
{
  "success": true,
  "data": {}
}
```

## Errors and retries

Check HTTP status and success. Business validation errors may return HTTP 200 with {"success":false,"message":"..."}; some include error.code. Authentication may return 401/403 and rate limiting 429. HTTP 200 alone does not guarantee success.

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

## Constraints

Account APIs use a system token and New-Api-User; an inference API key is not a substitute. Check success, as HTTP 200 can carry a business error.
