What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

A reverse-engineered unofficial API library for Xianyu (Goofish, Alibaba's second-hand marketplace) that wraps its HTTP endpoints and WebSocket private-message protocol, including decrypted sign signatures, base64/Protobuf message handling, cookie login, and token refresh. It serves as the foundation for building AI customer-service agents that automatically receive and reply to buyer messages.

Use cases

  • build an AI customer service agent for Xianyu sellers
  • automatically reply to Xianyu private messages with an LLM
  • send and receive Xianyu chat messages programmatically
  • fetch chat history and product details from Xianyu
  • upload images and send them as Xianyu messages
  • keep a persistent Xianyu login session alive for a bot
  • reverse engineer the Xianyu WebSocket messaging protocol

When to choose

  • you need to connect an LLM or rule engine to Xianyu's private messaging
  • you want a ready-made, working implementation of the Xianyu sign algorithm and WebSocket protocol
  • you are building an auto-reply or AI agent bot on top of Xianyu
  • you need programmatic access to Xianyu chat history, product info, and media upload

When to avoid

  • you need an officially supported and ToS-compliant marketplace API
  • you target platforms other than Xianyu/Goofish
  • you require a maintained release with a license or long-term stability guarantees
  • you cannot supply a logged-in browser cookie or run Node.js for the signing scripts
