# Customs Company Port Trade List

Query paginated port trade data for a company from customs data using the UpKuaJing Open Platform API.

## Overview

This skill provides access to paginated port trade data from UpKuaJing's customs database. Given a company ID and company type, it returns a list of ports with trade statistics including trade count, amount, quantity, weight, and percentage.

## Running Scripts

### Environment Setup

1. **Check Python**: `python --version`
2. **Install dependencies**: `pip install -r requirements.txt`

Script directory: `scripts/*.py`
Run example: `python scripts/*.py`

**Important**: Always use direct script invocation like `python scripts/customs_company_port_list.py`. **Do NOT use** shell compound commands like `cd scripts && python customs_company_port_list.py`

### Company Port List Query (`customs_company_port_list.py`)
- **Return granularity**: One record per port
- **Use cases**: Browse through a company's trade ports with detailed stats, analyze logistics routes and port-level trade volume
- **Examples**:
  - "List trade ports for company 100001 as a supplier"
  - "Get port-level trade details for company 100001 as a buyer"
- **Parameters**: See [Company Port List API](references/customs-company-port-list-api.md)

## API Key and Top-up

This skill requires an API key. The API key is stored in the `~/.upkuajing/.env` file:
```bash
cat ~/.upkuajing/.env
```
**Example file content**:
```
UPKUAJING_API_KEY=your_api_key_here
```
### **API Key Not Set**
First check if the `~/.upkuajing/.env` file has UPKUAJING_API_KEY;
If UPKUAJING_API_KEY is not set, prompt the user to choose:
1. User has one: User provides it (manually add to ~/.upkuajing/.env file)
2. User doesn't have one: You can apply using the interface (`auth.py --new_key`), the new key will be automatically saved to ~/.upkuajing/.env
Wait for user selection;

### **Account Top-up**
When API response indicates insufficient balance, explain and guide user to top up:
1. Create top-up order (`auth.py --new_rec_order`)
2. Based on order response, send payment page URL to user, guide user to open URL and pay, user confirms after successful payment;

### **Get Account Information**
Use this script to get account information for UPKUAJING_API_KEY: `auth.py --account_info`

## API Key and UpKuaJing Account
- Newly applied API key: Register and login at [UpKuaJing Open Platform](https://developer.upkuajing.com/), then bind account

## Fees

**All API calls incur fees**, different interfaces have different billing methods.

**Latest pricing**: Users can visit [Detailed Price Description](https://www.upkuajing.com/web/openapi/price.html)
Or use: `python scripts/auth.py --price_info` (returns complete pricing for all interfaces)

### Query Billing Rules

Billed by **number of calls**, each call returns a page of port list for one company:
- Each API call incurs a fee
- **Before execution:**
  1. Inform user that this query will incur a fee
  2. Stop, wait for explicit user confirmation in a separate message, then execute script

### Fee Confirmation Principle

**Any operation that incurs fees must first inform and wait for explicit user confirmation. Do not execute in the same message as the notification.**

## Workflow

### Decision Guide

| User Intent | Use API |
|-------------|---------|
| "List trade ports for company 100001 as a supplier" | Company Port List Query |
| "Show port-level trade breakdown for company 100001" | Company Port List Query |

## Usage Examples

### Query Company Port List

**User request**: "List trade ports for company 100001 as a supplier"
```bash
python scripts/customs_company_port_list.py --params '{"companyId":100001,"companyType":1}'
```

**Query the next page**:
```bash
python scripts/customs_company_port_list.py --params '{"companyId":100001,"companyType":1,"cursor":"eyJsYXN0X2lkIjogMTAwMX0="}'
```

**Query with filters**:
```bash
python scripts/customs_company_port_list.py --params '{"companyId":100001,"companyType":1,"dateStart":1700000000000,"dateEnd":1735689599999,"countryCodes":["KR"]}'
```

## Error Handling

- **API key invalid/non-existent**: Check `UPKUAJING_API_KEY` in `~/.upkuajing/.env` file
- **Insufficient balance**: Guide user to top up
- **Invalid parameters**: **Must first check the corresponding API documentation in references/ directory**, get correct parameter names and formats from documentation, do not guess

### API Documentation Reference

- Company Port List: Check [references/customs-company-port-list-api.md](references/customs-company-port-list-api.md)

## Best Practices

1. **Check API documentation**:
   - **Before executing queries, must first check the corresponding API reference documentation**
   - Check [references/customs-company-port-list-api.md](references/customs-company-port-list-api.md)
   - Do not guess parameter names, get accurate parameter names and formats from documentation

2. **Pagination**:
   - Use the `cursor` parameter from the response to fetch the next page
   - If no `cursor` is returned in the response, there are no more pages

3. **Data interpretation**:
   - `percentTrade` is the percentage of trade (as a decimal, e.g., 45.67 means 45.67%)
   - `port` is the port name (e.g., "BUSAN")

4. **Cross-skill usage**:
   - The company ID can be obtained from **customs-company-stats** or **upkuajing-customs-trade-company-search**
   - Port names from results can be used to filter data in **customs-company-trends** and **customs-company-partner-stats**

## Notes
- `companyType` determines the company's role (1=supplier, 2=buyer)
- Use `cursor` for pagination — it's a base64-encoded string
- File paths use forward slashes on all platforms
- **Prohibit outputting technical parameter format**: Do not display code-style parameters in responses, convert to natural language
- **Do not** estimate or guess per-call fees — use `python scripts/auth.py --price_info` to get accurate pricing information
- **Do not** guess parameter names, get accurate parameter names and formats from documentation
