# 快速开始

## 1. 完成 KYC（一次性）

ISP 需先通过实名验证。**控制台 → 账户 → KYC**，通常 1 个工作日内审核。详见 [身份验证 (KYC)](/helodata-zh/zhang-hu-yu-ji-fei/kyc.md)。

## 2. 下单 ISP IP

1. 进入 **控制台 → ISP → 下单**。
2. 选择**国家**（如该国支持则可选**城市**）。
3. 选择**数量**——单笔最少 5 个、最多 5,000 个。
4. 选择**计费周期**——按月或按年（9 折）。
5. 点击 **下单**。T1 国家通常 1–5 分钟内交付，长尾国家最长 24 小时。

批次就绪后会发邮件通知。

## 3. 下载清单

1. 打开 **控制台 → ISP → 我的 IP → {批次}**。
2. 点击 **下载**，选择格式：
   * **`ip:port:user:pass`**（默认）— 每行一个 IP
   * **CSV** — 列 `ip,port,user,pass,country,city,asn`
   * **JSON** — 完整元数据，含 ASN 与城市
   * **Proxifier / FoxyProxy / SwitchyOmega** — 可直接导入的文件

或通过 API：

```bash
curl -H "Authorization: Bearer API_KEY" \
     "https://api.helodata.com/v1/isp/batches/{batch_id}/ips?format=plain"
```

完整说明见 [代理清单格式](/helodata-zh/chan-pin/overview-2/proxy-list-format.md)。

## 4. 发送请求

任取清单中一个 IP：

### curl

```bash
curl -x http://helo_s1a2b3c4d5e:PASSWORD@198.51.100.42:8000 \
     https://ipv4.icanhazip.com
```

返回应严格是 `198.51.100.42`——这是静态 IP。

### Python (requests)

```python
import requests

PROXY = "http://helo_s1a2b3c4d5e:PASSWORD@198.51.100.42:8000"

r = requests.get(
    "https://ipv4.icanhazip.com",
    proxies={"http": PROXY, "https": PROXY},
    timeout=30,
)
print(r.text.strip())
```

### Node.js (undici)

```js
import { fetch, ProxyAgent } from "undici";

const agent = new ProxyAgent(
  "http://helo_s1a2b3c4d5e:PASSWORD@198.51.100.42:8000"
);
const res = await fetch("https://ipv4.icanhazip.com", { dispatcher: agent });
console.log((await res.text()).trim());
```

### Go (net/http)

```go
package main

import (
    "fmt"
    "io"
    "net/http"
    "net/url"
)

func main() {
    proxyURL, _ := url.Parse("http://helo_s1a2b3c4d5e:PASSWORD@198.51.100.42:8000")
    client := &http.Client{Transport: &http.Transport{Proxy: http.ProxyURL(proxyURL)}}
    resp, _ := client.Get("https://ipv4.icanhazip.com")
    defer resp.Body.Close()
    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}
```

### PHP (cURL)

```php
<?php
$ch = curl_init('https://ipv4.icanhazip.com');
curl_setopt_array($ch, [
    CURLOPT_PROXY          => 'http://198.51.100.42:8000',
    CURLOPT_PROXYUSERPWD   => 'helo_s1a2b3c4d5e:PASSWORD',
    CURLOPT_RETURNTRANSFER => true,
]);
echo trim(curl_exec($ch));
curl_close($ch);
```

## 5. 使用整批清单（轮换）

加载清单，按请求挑下一个 IP。简单轮询：

```python
import itertools, requests

with open("isp.txt") as f:
    proxies = [line.strip() for line in f if line.strip()]

pool = itertools.cycle(proxies)                                  # 每行 ip:port:user:pass

def get(url):
    line = next(pool)
    ip, port, user, password = line.split(":", 3)
    p = f"http://{user}:{password}@{ip}:{port}"
    return requests.get(url, proxies={"http": p, "https": p}, timeout=30)
```

* [身份认证](/helodata-zh/chan-pin/overview-2/authentication.md) — 切换到 IP 白名单
* [IP 管理](/helodata-zh/chan-pin/overview-2/ip-management.md) — 替换失效 IP、刷新批次

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.helodata.com/helodata-zh/chan-pin/overview-2/quick-start.md?ask=<question>
