API Management Platform Construction, Lifecycle Governance, and AI‑Driven Technical Debt Mitigation

After years of refactoring Tencent News services, many legacy APIs remain without unified documentation or mock capabilities, leading to low development efficiency and high manual communication cost.

The presentation outlines the problems, the construction of an interface management platform, lifecycle governance, and explores AI‑driven technical debt solutions.

1. Problems

Missing automated documentation, scattered docs in iWiki, Tencent Docs, YAPI; no unified mock; low efficiency; protocol changes require manual communication; no interface version control; no retirement mechanism.

2. Interface Management Platform Construction

Evaluation of platforms: Swagger and YAPI. Swagger provides UI and mock but lacks advanced features; YAPI offers permission management, dynamic mock, and easy integration.

Chosen solution: YAPI for documentation, mock, and automation.

Key features:

Swagger UI for documentation and testing.

YAPI mock with header rule name and parameter‑list support.

Code example for YAPI tags:

@alias=/sports/Medal @yapi-tags=列表分类 奖牌榜 @yapi-method=get

Automation of PB to Swagger conversion using trpc‑cli and custom scripts.

3. Interface Lifecycle Governance

Full lifecycle view, deprecation agreements, two‑level audit, monitoring of low‑traffic and mock interfaces, automated reporting.

Monitoring indicators: daily request volume, mock interface count, health thresholds.

4. AI‑Driven Technical Debt Management

Using large language models to detect code debt, assist in protocol field retirement, and provide RAG‑based query bots.

Example of code extraction:

def split_go_doc(repo_path="/data/swag", chunk_size=1024, chunk_overlap=0) -> List[Document]:

Implementation of embedding, question translation, and retrieval pipelines.

Demonstrated query: “请问下有没有 Schema 的 name 字段相关信息” returns the relevant struct definition.

5. Summary

All 26 core repositories are synchronized to YAPI, achieving 750+ daily mock uses, and establishing a sustainable interface governance process.
