# Compatible quota information

Compatible quota information. Read-only compatibility for legacy clients.

## Endpoint and authentication

`GET https://api.tu-zi.com/v1/dashboard/billing/subscription`

Transport: json

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

```http
Authorization: Bearer YOUR_API_KEY
```

## 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.

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 GET 'https://api.tu-zi.com/v1/dashboard/billing/subscription' \
  --header 'Authorization: Bearer YOUR_API_KEY'
```

### python

```python
import json
import os
import requests

url = "https://api.tu-zi.com/v1/dashboard/billing/subscription"
headers = json.loads("{\"Authorization\":\"Bearer YOUR_API_KEY\"}")
headers["Authorization"] = "Bearer " + os.environ["API_KEY"]
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/v1/dashboard/billing/subscription";
const headers = {
  "Authorization": "Bearer YOUR_API_KEY"
};
headers.Authorization = 'Bearer ' + process.env.API_KEY;
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 |
| --- | --- | --- |
| object | string | billing_subscription. |
| soft_limit_usd | number | Displayed total granted quota, not remaining quota. Despite the usd suffix, units follow site settings. |
| hard_limit_usd | number | Same as soft_limit_usd. |
| system_hard_limit_usd | number | Same as soft_limit_usd. |
| access_until | integer | Expiry in Unix seconds; 0 means no expiry. |

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

```json
{
  "object": "billing_subscription",
  "has_payment_method": true,
  "soft_limit_usd": 10,
  "hard_limit_usd": 10,
  "system_hard_limit_usd": 10,
  "access_until": 0
}
```

## 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

An alias exists without /v1. Use an inference key. DisplayTokenStatEnabled selects key or account cumulative values; open-platform keys always use their own values. Units follow USD/CNY/TOKENS display settings, not field names alone. Date-range filtering is not implemented; use account log statistics for time filters. Unlimited quota uses a limit placeholder of 100000000.
