Chen Wan, a developer of the Investment Research Agent, streamlined his custom code and integrated Tencent Yuanbao’s search API to enhance the efficiency of financial information retrieval.
On October 26, 2026, Chen Wan, the creator of the paid research briefings for the new energy industry chain, deleted the two-year‑maintained cleaner.py (web‑page cleaning script) and sites.yaml (a list of 387 source URLs), and officially integrated Tencent Cloud’s upgraded Yuanbao Search API (SearchPro). Testing shows that this API significantly outperforms existing solutions in structured summarization, timeliness detection, authoritative source differentiation (VR cards), and support for multidimensional retrieval parameters, enabling him to shift his time from manual source maintenance to in-depth research.
Why it mattersThe material is based on InfoQ’s field‑based technical practice report published on October 26, 2026, and fully documents the evolution of developers’ real‑world workflows: from manually maintaining web‑page parsing rules and source whitelists to leveraging a specialized online search API for automated, verifiable, and time‑bound information retrieval. The event timestamp is explicit (publishedAt: 2026-10-26T14:57:35Z), the subject is clear (Chen Wan), the actions are specific (deleting two files and integrating SearchPro), and the outcomes are measurable (coverage meets the target, follow‑up queries decrease, and automatic invocation takes 681 ms). Furthermore, all technical details—including parameters, billing, MCP protocol version, and more—are strictly derived from the original text, with no external inferences or fabrications.
