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.
How to Invoke
- API Endpoint:
POST /jiimore/getNicheInfoByKeyword (complete params/response/error codes in references/api.md)
- Python Script:
python scripts/amazon_niche_info_by_keyword.py '<JSON params>' [--inline]
- Cost constraint: This tool consumes credits; the same session and parameter combination is called only once by default, with a 24h local cache in the script. On failure or empty results, do not automatically retry with different keywords, pagination, or postal codes; inform the user about additional consumption before continuing to search.
Output strategy (script default behavior):
- Always write the full response to
<cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-jiimore-get-niche-info-by-keyword-<timestamp>.json (<cwd> is the working directory at script execution time, i.e. the current project directory in Claude Code; <session> is taken from the SESSION_ID env var, auto-grouped by user task; do not write to /tmp, error if current directory is not writable)
- Response body <= 8 KB: print full JSON to stdout after saving
- Response body > 8 KB: print only summary to stdout after saving (top-level fields, common counts like
total/costToken, length of largest list field + first 3 samples)
- Add
--inline to force full output to stdout (still saves to disk)
Data reading tip: Check the summary first to decide if it's enough; when specific fields are needed, prefer using jq or ConvertFrom-Json to extract from the saved json file on demand, avoiding loading the entire JSON into context.
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.

Display Rules
- Present data clearly: Show query results in well-structured tables. Convert decimal ratios to percentages for readability (e.g., 0.25 -> 25%).
- 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.
- Translate niche titles: When the
translationZh field is present and the user prefers Chinese, show it alongside the original nicheTitle.
- Pagination guidance: When
total exceeds the current page size, inform the user of the total count and suggest fetching additional pages if needed.
- 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).
- CPC display: When CPC data is present, show all three tiers (low, medium, high) to give a complete advertising cost picture.
- 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.

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.
