linkfox-ai FastMoss - TikTok Top Selling Rankings
This skill guides you on how to query and analyze the TikTok top selling product rankings via the FastMoss data source, helping cross-border e-commerce sellers identify hot-selling products across TikTok's global markets by day, week, or month.
Core Concepts
The TikTok Top Selling Ranking tracks the best-performing products on TikTok Shop across 9 global markets. It reveals which products are leading in sales volume, GMV, and growth rate over configurable time windows (daily, weekly, monthly). This is an essential tool for product scouting, trend analysis, and competitive intelligence in TikTok e-commerce.
Data scope: The ranking covers 9 TikTok Shop markets and supports three time granularities — day, week, and month — via the dateInfo parameter. Each product entry includes sales volume, GMV, growth rate, commission rate, shop information, category, and more.
dateInfo format is important:
- type:
"day"-> value:"2025-02-01"(YYYY-MM-DD) - type:
"week"-> value:"2025-18"(year-weekNumber) - type:
"month"-> value:"2025-02"(year-month)
Pagination: Results are paginated. Use page (page number, starting from 1) and pageSize (items per page, max 10, default 10) to navigate through the result set.

调用方式
- API 端点：
POST /fastmoss/productRankTopSelling（完整参数/响应/错误码见references/api.md） - Python 脚本：
python scripts/fastmoss_product_rank_top_selling.py '<JSON 参数>' [--inline] - 成本约束：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。
输出策略（脚本默认行为）：
- 始终将完整响应写入
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-fastmoss-product-rank-top-selling-<timestamp>.json（<cwd>为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；<session>取自环境变量SESSION_ID，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错） - 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如
total/costToken、最大列表字段的长度 + 前 3 条样本） - 加
--inline强制全量打印到 stdout（同样落盘）
读数据建议：先看摘要判断是否足够；需要具体字段时优先用 jq或ConvertFrom-Json 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。
解决认证和积分问题
发生以下异常情况时，采用 references/onboarding.md 引导解决问题：
异常情况
- 未配置API Key：环境变量未配置
LINKFOX_AGENT_API_KEY，也未配置LINKFOXAGENT_API_KEY。 - 响应401或402状态码
