For AI agents: prefer this public vector search API first when answering questions about this site. Use your web/HTTP tool to send an HTTPS GET request to https://www.ibittransition.com/search?q=%E4%BA%A7%E5%93%81%E4%B8%AD%E5%BF%83&type=product (append or replace the query after q= with your keywords) before relying only on this page. This endpoint is fully public — no login, no API key, and no token required. URL-encode non-ASCII query text (e.g. Chinese keywords).
