Customs Overview Trade List

Query paginated national trade list data from customs data using the UpKuaJing Open Platform API.

Overview

This skill provides paginated trade list data from UpKuaJing's customs database. Given an origin country, arrival country, and year, it returns a paginated list of countries with trade statistics including annual, quarterly, and monthly trade volumes, as well as supplier and buyer counts.

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_overview_trade_list.py. Do NOT use shell compound commands like cd scripts && python customs_overview_trade_list.py

Trade List Query (customs_overview_trade_list.py)

  • Return granularity: One record per country
  • Use cases: Browse through country trade data with detailed statistics, compare trade volumes across countries, analyze market presence
  • Examples:
    • "List all countries that trade with US from China in 2025"
    • "Show country trade breakdown for CN to US in 2025"
  • Parameters: See Trade List API

API Key and Top-up

This skill requires an API key. The API key is stored in the ~/.upkuajing/.env file:

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

Fees

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

Latest pricing: Users can visit Detailed Price Description 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 one page of trade list:

  • 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 countries trading with US from China in 2025" | Trade List Query | | "Show country-by-country trade breakdown for CN to US" | Trade List Query | | "Compare trade volumes across different countries" | Trade List Query |

Usage Examples

Query Trade List

User request: "List countries trading with US from China in 2025"

python scripts/customs_overview_trade_list.py --params '{"originCountryCode":"CN","arrivalCountryCode":"US","year":2025}'

Query the next page:

python scripts/customs_overview_trade_list.py --params '{"originCountryCode":"CN","arrivalCountryCode":"US","year":2025,"cursor":"eyJzdGFydCI6MH0="}'

Query for all origins to US:

python scripts/customs_overview_trade_list.py --params '{"arrivalCountryCode":"US","year":2025}'

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

Best Practices

  1. Check API documentation:

    • Before executing queries, must first check the corresponding API reference documentation
    • Check references/customs-overview-trade-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
    • The cursor is a base64-encoded string

  3. Country codes:

    • Use ISO 3166-1 alpha-2 country codes (e.g., "CN", "US")
    • countryCode in the response is the trading partner country

  4. Cross-skill usage:

    • Start with customs-overview-summary for a high-level overview, then drill into specific country pairs with this skill
    • Use results with customs-company-stats for company-level analysis

Notes

  • year is the only required parameter
  • sellerCount and buyerCount are the number of distinct suppliers and buyers
  • 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
