WeChat Pay has released AI Toolbox 2.0, where all charts have been converted to Mermaid to reduce Token consumption by half.

According to WatchBeat Monitoring, WeChat Pay today released the AI Access Toolbox 2.0, a comprehensive upgrade to the knowledge base and development tools for large model integration. The toolbox converts all timeline diagrams and state diagrams in the documentation to the Mermaid format, allowing models without multimodal capabilities to be directly readable, reducing overall Token consumption by 50% compared to the original HTML.

To eliminate machine translation biases, the toolbox supports 9 languages, including Chinese, Japanese, Korean, and adapts translations to native concepts such as "WeChat Pay Checkout." The knowledge base content has expanded from 1.0's payment and coupon focus to cover the entire WeChat Pay product line, while providing two AI expert capabilities: technical experts and financial-grade R&D experts, supporting troubleshooting Q&A and code quality reviews.

On the development experience front, the new CLI dynamic debugging feature allows developers to query payment and refund status directly using natural language in the terminal, avoiding interruptions to the coding flow by logging into the merchant backend. The Skill will also automatically compare the official website with the local knowledge base version at startup, enabling automatic synchronization updates.
