Linkfox Sif Asin Keywords

SIF ASIN Keyword Analysis

This skill guides you on how to query and analyze traffic keywords for a specific Amazon ASIN, helping Amazon sellers understand which keywords drive traffic to a product and how that product ranks for each keyword.

Core Concepts

SIF ASIN Keyword data reveals the keywords that bring traffic to a specific Amazon product (ASIN). For each keyword, you can see the product's organic search rank, SP ad rank, search volume, traffic share, display position types, and various performance markers. This is the go-to tool for reverse ASIN keyword lookup.

Single-ASIN limitation: This tool queries one ASIN at a time. If the user wants to compare multiple ASINs, you must make separate queries for each.

Ranking logic: A smaller rank value means a better (higher) position. Rank 1 means the product appears first in search results. When a user says "ranking improved", the numeric value decreased; "ranking dropped" means the value increased.

Data Fields

Per-keyword record (each element of data)

Top-level response fields (alongside data)

Supported Marketplaces

13 marketplaces: US (United States), UK (United Kingdom), DE (Germany), CA (Canada), JP (Japan), FR (France), ES (Spain), IT (Italy), MX (Mexico), AU (Australia), AE (United Arab Emirates), BR (Brazil), SA (Saudi Arabia).

Default marketplace is US. Use US when the user does not specify a marketplace. Codes outside this list will be rejected by the API pattern.

调用方式

• API 端点：POST /sif/asinKeywords（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/sif_asin_keywords.py '<JSON 参数>' [--inline]
• 成本约束：本工具会消耗算力；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-sif-asin-keywords-<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。

解决认证和算力问题

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
• 响应提示算力或余额不足：消息含"算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。
