# Express Tracker（快递物流查询）

Track packages from 200+ carriers (Chinese domestic + international) via Kuaidi100 API.

Setup (Required)

Users must obtain their own Kuaidi100 API credentials:

1. **Register** at [Kuaidi100 Open Platform](https://api.kuaidi100.com/register/enterprise)

- 注册企业版账号（个人也可注册）

- Free tier: 100 queries/day after verification

2. **Get credentials** from the [Kuaidi100 Dashboard](https://api.kuaidi100.com/home):

- **授权 Key（API Key）**: Found in 授权信息 → 授权key

- **Customer ID**: Found in 授权信息 → customer

3. **Set environment variables**:

```bash

export EXPRESS_TRACKER_KEY="your_api_key_here"

export EXPRESS_TRACKER_CUSTOMER="your_customer_id_here"

```

For persistent config, add to `~/.bashrc` or `~/.zshrc`:

```bash

echo 'export EXPRESS_TRACKER_KEY="your_key"' >> ~/.zshrc

echo 'export EXPRESS_TRACKER_CUSTOMER="your_customer"' >> ~/.zshrc

```

Usage

# Auto-detect carrier and query
scripts/track.sh <tracking_number>

# Specify carrier manually
scripts/track.sh <tracking_number> <carrier_code>

Examples

# Auto-detect (recommended)
scripts/track.sh 770308811947591

# Specify carrier explicitly
scripts/track.sh SF1234567890 shunfeng

How It Works

1. **Carrier auto-detection**: Local rule-based matching by tracking number prefix/length/format

2. **API query**: Sends signed request to Kuaidi100 poll API with `resultv2=4` for advanced status

3. **Output**: Formatted timeline with full tracking history (newest first)

Supported Carriers (Auto-Detection)

| Prefix/Pattern | Carrier | Code |

|---|---|---|

| `SF` | 顺丰速运 | `shunfeng` |

| `YT` | 圆通速递 | `yuantong` |

| `JT` / `J0` | 极兔速递 | `jitu` |

| `JD` | 京东快递 | `jd` |

| `CN` | 菜鸟速递 | `cainiao` |

| `10/11/12/13/19/46` + 13 digits | 韵达快递 | `yunda` |

| `77/88/66/55/44` + 13-15 digits | 申通快递 | `shentong` |

| `E` + letter + 9 digits + 2 letters | EMS | `ems` |

If auto-detection fails, specify the carrier code manually as the second argument.

Agent Integration

When a user provides a tracking number, run:

EXPRESS_TRACKER_KEY="$KEY" EXPRESS_TRACKER_CUSTOMER="$CUSTOMER" scripts/track.sh <number>

Parse the output and present the tracking timeline to the user. If carrier detection fails, ask the user which carrier it is.
