Setup (Required)
Users must obtain their own Kuaidi100 API credentials:

- 注册企业版账号（个人也可注册） - Free tier: 100 queries/day after verification
- Get credentials from the Kuaidi100 Dashboard:
- 授权 Key（API Key）: Found in 授权信息 → 授权key - Customer ID: Found in 授权信息 → customer
- Set environment variables:
export EXPRESS_TRACKER_KEY="your_api_key_here"
export EXPRESS_TRACKER_CUSTOMER="your_customer_id_here"For persistent config, add to ~/.bashrc or ~/.zshrc:
echo 'export EXPRESS_TRACKER_KEY="your_key"' >> ~/.zshrc
echo 'export EXPRESS_TRACKER_CUSTOMER="your_customer"' >> ~/.zshrcUsage
# 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 shunfengHow It Works
- Carrier auto-detection: Local rule-based matching by tracking number prefix/length/format
- API query: Sends signed request to Kuaidi100 poll API with
resultv2=4for advanced status - Output: Formatted timeline with full tracking history (newest first)
