sourcing▌

这是跨境电商选品的供应链工具。在 1688 找到核心工厂和起批价，为核价计算提供成本数据。

Expert in event sourcing, CQRS, and event-driven architecture patterns. Masters event store design, projection building, saga orchestration, and eventual consistency patterns. Use PROACTIVELY for event-sourced systems, audit trail requirements, or complex domain modeling with temporal queries.

Search 1688.com (Alibaba's China-domestic wholesale platform) by keyword and return structured offers — title, CNY wholesale price, MOQ, supplier name + location, recent-transaction count, and canonical offer URL. Supports price-range, supplier-province, and sort filters. Headed browsers are hard-blocked at IP level (cloud_ip_bl); the recommended path is the mtop JSON API at h5api.m.1688.com with md5-signed requests.

Store state changes as a sequence of events rather than the current state, enabling temporal queries, audit trails, and event replay.
