Jiimore Niche Info by Keyword

This skill guides you on how to query and analyze Amazon niche market data by keyword, helping Amazon sellers evaluate market segments for competitive intensity, brand maturity, pricing structure, and entry opportunity.

调用方式

• API 端点：POST /jiimore/getNicheInfoByKeyword（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/jiimoregetnicheinfoby_keyword.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-jiimore-get-niche-info-by-keyword-<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 LINKFOXAGENTAPIKEY，也未配置 LINKFOXAGENTAPI_KEY。
• 响应401或402状态码
• 响应提示积分或余额不足：消息含"积分余额不足/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。

Core Concepts

A niche (sub-market segment) is a grouping of products that share a common keyword theme on Amazon. This tool returns rich analytical dimensions for each niche, including search volume, sales volume, click-through rates, brand count, top-brand concentration, new product launch success rates, CPC estimates, and a composite demand score. Data is available for US, JP, and DE marketplaces.

Keyword is required: Every query must include a keyword. The keyword should be provided in the language of the target marketplace (e.g., English for US, Japanese for JP, German for DE). When the user provides a keyword in a different language, translate it to the marketplace language before calling the API.

Percentage fields: Several parameters and response fields use a 0-1 decimal range representing 0%-100%. When displaying these values to users, convert them to percentages (e.g., 0.35 -> 35%).

Demand score: The demand field is a composite opportunity score assigned to each niche. A higher value indicates greater market demand potential.

Usage Examples

1. Basic niche exploration by keyword Query niches related to "wireless earbuds" in the US market, sorted by weekly sales volume:

{
  "keyword": "wireless earbuds",
  "countryCode": "US",
  "sortField": "unitsSoldT7",
  "sortType": "desc"
}

2. Low-competition niche discovery Find niches for "yoga mat" where the top 5 brands hold less than 50% click share and brand count exceeds 20:

{
  "keyword": "yoga mat",
  "countryCode": "US",
  "top5BrandsClickShareMax": 0.5,
  "brandCountMin": 20,
  "sortField": "demand",
  "sortType": "desc"
}

3. High-demand, high-conversion niches Find niches for "phone case" with weekly search volume above 10000 and click conversion rate above 10%:

{
  "keyword": "phone case",
  "countryCode": "US",
  "searchVolumeT7Min": 10000,
  "clickConversionRateT7Min": 0.1,
  "sortField": "searchVolumeT7",
  "sortType": "desc"
}

4. New product opportunity analysis Find niches for "LED light" with high new product success rate (above 20%) and low return rate (below 5%):

{
  "keyword": "LED light",
  "countryCode": "US",
  "launchRateT180Min": 0.2,
  "returnRateT360Max": 0.05,
  "sortField": "launchRateT180",
  "sortType": "desc"
}

5. Japanese market niche research Explore niches related to headphones in Japan, sorted by demand score:

{
  "keyword": "\u30d8\u30c3\u30c9\u30db\u30f3",
  "countryCode": "JP",
  "sortField": "demand",
  "sortType": "desc"
}

6. Price-range-specific niche analysis Find niches for "backpack" with average price between $20 and $50 and low advertising saturation:

{
  "keyword": "backpack",
  "countryCode": "US",
  "avgPriceMin": 20,
  "avgPriceMax": 50,
  "sponsoredProductsPercentageMax": 0.3,
  "sortField": "unitsSoldT7",
  "sortType": "desc"
}

Display Rules

1. Present data clearly: Show query results in well-structured tables. Convert decimal ratios to percentages for readability (e.g., 0.25 -> 25%).
2. Highlight key metrics: Always surface the niche title, demand score, weekly search volume, weekly sales, brand count, and top 5 brands click share as primary columns.
3. Translate niche titles: When the translationZh field is present and the user prefers Chinese, show it alongside the original nicheTitle.
4. Pagination guidance: When total exceeds the current page size, inform the user of the total count and suggest fetching additional pages if needed.
5. Error handling: When a query fails, explain the reason based on the response message and suggest adjusting filter criteria (e.g., broadening ranges or checking the keyword).
6. CPC display: When CPC data is present, show all three tiers (low, medium, high) to give a complete advertising cost picture.
7. No subjective advice: Present data objectively without adding unsolicited business recommendations. Only provide interpretation when explicitly requested by the user.

Important Limitations

• Supported marketplaces: Only US, JP, and DE are available. Other marketplace codes will be rejected.
• Keyword required: Every query must include a keyword. The API will not return results without one.
• Result cap: Maximum 100 results per page.
• Percentage values: All rate/share parameters use 0-1 range, not 0-100. Ensure correct values when constructing filters.

User Expression & Scenario Quick Reference

Applicable -- Niche-level market segment analysis by keyword:

Not applicable -- Needs beyond niche-level segment data:

• Individual ASIN performance or sales estimation
• Search term ranking trends (use ABA data tools instead)
• Advertising campaign management or bid optimization
• Product review analysis or listing optimization
• Supplier sourcing or logistics planning

Boundary judgment: When users say "market research" or "product opportunity", if their intent focuses on evaluating the competitive landscape and demand potential of keyword-level market segments, this skill applies. If they need ASIN-level data, search term ranking trends, or comprehensive business strategy, direct them to the appropriate tool.
