Treasury API Lifecycle Manager is a skill by infochen-sub that provides comprehensive API management tools for the China Postal Savings Bank (PSBC) treasury system. It enables developers to explore, validate, test, and generate code for 20 financial APIs spanning transaction codes 601113 through 601732. The skill serves as a complete reference and testing companion for teams integrating with the PSBC treasury platform.

Key Features

API discovery and documentation -- Lists all 20 available treasury APIs with full HTTP specifications, request/response schemas, and message format documentation.
Response code reference -- Provides a complete catalog of standard HTTP codes (200, 400, 401, etc.) and PSBC-specific business error codes with detailed explanations.
Message validation -- Includes a
```
validator.py
```
utility that performs JSON Schema validation and field legality checking against the treasury API specifications.
Code generation -- Produces runnable examples in curl, Postman, and Python formats, ready to use for integration testing.
Mock response generation -- Creates success and failure response scenarios with configurable delays for local development and testing without connecting to production systems.
Chinese national cryptography support -- Documents SM4 symmetric and SM2 asymmetric encryption requirements at Security Level 10 (encrypted) and Level 15 (signature-only).

Use Cases

API integration development -- Developers building treasury system integrations can explore available endpoints, understand request formats, and generate working code samples without digging through separate documentation portals.
Testing and QA -- QA teams can use the mock response generator and validator to build comprehensive test suites that cover success paths, error scenarios, and edge cases.
Security compliance verification -- Teams can reference the cryptography documentation to ensure their implementations meet PSBC security requirements for GM (Guomi) certificate encryption.
Onboarding new developers -- New team members can use the skill as an interactive reference guide to quickly understand the treasury API landscape and message formats.

How It Works

The skill bundles API specifications (

apis.json

), response codes (

response-codes.json

), a Python validator (

validator.py

), and a mock server (

mock.py

) into a single package. Users interact with these resources through natural language queries, and the skill provides relevant documentation, validation results, or generated code based on the request.

Getting Started

Install the skill from ClawHub -- no external dependencies required.
Ask about available APIs to see the full list of 20 treasury endpoints.
Request documentation for a specific transaction code (e.g., 601113) to get full request/response schemas.

Use the validator to check message payloads:

python validator.py --input payload.json --api 601113

Generate mock responses for local testing without production access.
