Customs Company HS Code Trade List

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

Overview

This skill provides access to paginated HS code trade data from UpKuaJing's customs database. Given a company ID and company type, it returns a list of HS codes 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_hscode_list.py. Do NOT use shell compound commands like cd scripts && python customs_company_hscode_list.py

Company HS Code List Query (customs_company_hscode_list.py)

• Return granularity: One record per HS code
• Use cases: Browse through a company's HS codes with detailed stats, drill down into specific product categories
• Examples:
  • "List HS codes for company 100001 as a supplier"
  • "Get HS code details for company 100001 as a buyer"
• Parameters: See Company HS Code 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

• Newly applied API key: Register and login at UpKuaJing Open Platform, then bind account

Report Skill Call Errors

When an API call fails or returns abnormal data (server error, timeout, malformed response, etc.), explain the anomaly to the user in natural language and ask whether to report it to the platform for troubleshooting. Only run the report after user confirmation:

python scripts/error_report.py --params '{"requestPath":"/agent/customs/company/hscode/list","requestId":"f47ac10b58cc4372a5670e02b2c3d479","context":"Company HS code list query failed with a server error"}'

• Do not report normal business conditions (insufficient balance, invalid API key, parameter errors) — handle them via their own flows
• Error reporting does not incur query fees
• Parameters: See Error Report API

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 a page of HS code 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.

Usage Examples

Query Company HS Code List

User request: "List HS codes for company 100001 as a supplier"

python scripts/customs_company_hscode_list.py --params '{"companyId":100001,"companyType":1}'

Query the next page:

python scripts/customs_company_hscode_list.py --params '{"companyId":100001,"companyType":1,"cursor":"eyJsYXN0X2lkIjogMTAwMX0="}'

Query with filters:

python scripts/customs_company_hscode_list.py --params '{"companyId":100001,"companyType":1,"dateStart":1700000000000,"dateEnd":1735689599999,"countryCodes":["US"]}'

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
• Skill call errors / abnormal responses: Explain to the user and, with user confirmation, report to the platform via python scripts/error_report.py (see Report Skill Call Errors)

API Documentation Reference

• Company HS Code List: Check references/customs-company-hscode-list-api.md
• Error Report: Check references/skill-error-report-api.md

Best Practices

1. Check API documentation:

   • Before executing queries, must first check the corresponding API reference documentation
   • Check references/customs-company-hscode-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., 23.45 means 23.45%)
   • hscode is the HS code string (e.g., "847130")

4. Cross-skill usage:

   • The company ID can be obtained from customs-company-stats or upkuajing-customs-trade-company-search
   • HS codes 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
