Package Tracker

Purpose

Helps implement and use a unified package tracking layer that can integrate multiple courier APIs (starting with 快递鸟). Use this skill when:

• User wants to track a parcel by tracking number
• User asks to integrate express/courier query in code
• User mentions 快递鸟, Kdniao, or “快递查询”

Quick Start

1. Config: Copy package_tracker.json.example to package_tracker.json, then fill in providers.kdniao.ebusiness_id and providers.kdniao.api_key.

1. Query (Python):

```bash

# Run in the skill directory (where this SKILL.md lives)

python -m package_tracker track

# e.g. python -m package_tracker track ZTO 638650888018

```

1. In code:

```python

from package_tracker import get_tracker

tracker = get_tracker()

result = tracker.track(shipper_code="ZTO", logistic_code="638650888018")

```

Provider: 快递鸟 (Kdniao)

• 即时查询 RequestType: 1002
• Endpoint: https://api.kdniao.com/Ebusiness/EbusinessOrderHandle.aspx
• RequestData (JSON): ShipperCode, LogisticCode, optional OrderCode, optional CustomerName (required for 顺丰 SF: last 4 digits of phone)
• Sign: RequestData (unencoded JSON, no spaces) + ApiKey → MD5 → Base64 → URL-encode

Do not put API keys in code; store them in package_tracker.json (and avoid committing it).

Adding Another Provider

1. Add a new module under package_tracker/ implementing the same track interface (e.g. track(shipper_code, logistic_code, **kwargs) -> dict).
2. Register it in package_tracker/registry.py, then select it via config (default) or pass provider=... in get_tracker(...).
