# Export account usage CSV

Export account usage CSV within the current credential scope.

## Endpoint and authentication

`GET https://api.tu-zi.com/api/log/self/export`

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
```

## Query parameters

| Field | Type | Required | Description / constraints |
| --- | --- | --- | --- |
| start_timestamp | integer | Yes | Start Unix seconds, required. |
| end_timestamp | integer | Yes | End Unix seconds, required; range cannot exceed 90 days. |
| model_name | string | No | Model filter. |
| type | integer | No | Log type filter. |

## 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/log/self/export?start_timestamp=1700000000&end_timestamp=1700086400' \
  --header 'Authorization: Bearer YOUR_SYSTEM_TOKEN' \
  --header 'New-Api-User: YOUR_USER_ID' \
  --output 'usage.csv'
```

### python

```python
import json
import os
import requests

url = "https://api.tu-zi.com/api/log/self/export?start_timestamp=1700000000&end_timestamp=1700086400"
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()
if "json" in response.headers.get("Content-Type", "").lower():
    raise RuntimeError("Expected binary content, received JSON: " + response.text)
with open("usage.csv", "wb") as output:
    output.write(response.content)
```

### javascript

```javascript
import { writeFile } from 'node:fs/promises';
// Node.js 20+
const url = "https://api.tu-zi.com/api/log/self/export?start_timestamp=1700000000&end_timestamp=1700086400";
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());
if ((response.headers.get("content-type") || "").toLowerCase().includes("json")) throw new Error("Expected binary content, received JSON: " + await response.text());
await writeFile("usage.csv", Buffer.from(await response.arrayBuffer()));
```

## Response fields

| Field | Type | Description / constraints |
| --- | --- | --- |
| CSV | binary | UTF-8 CSV on success; failures may be JSON success:false. |

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

Replace example timestamps with the required Unix-second range. Account exports use a system token; key exports use that key. Check status and Content-Type before saving the CSV.
