Jiimore Niche Info by ASIN
This skill guides you on how to query and analyze Amazon niche market data by a reference ASIN, helping Amazon sellers evaluate market segments for competitive intensity, brand maturity, pricing structure, and entry opportunity.
How to Invoke
API Endpoint: POST /jiimore/getNicheInfoByAsin (complete params/response/error codes in references/api.md)
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 ASINs, marketplaces, or relaxed filters; 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-asin-<timestamp>.json ( is the working directory at script execution time, i.e. the current project directory in Claude Code; is taken from the env var, auto-grouped by user task; , error if current directory is not writable)
<cwd>
<session>
SESSION_ID
do not write to /tmp
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 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. Given a reference ASIN, this tool finds the niche segments that ASIN belongs to and returns rich analytical dimensions for each, 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.
ASIN is required: Every query must include an asin. The tool locates the niche segments associated with that ASIN and returns them with detailed metrics. Use this when the user already has a specific product (ASIN) in hand and wants to understand the market segments it competes in -- as opposed to keyword-driven niche discovery.
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.
Parameter Guide

Parameter
Type
Description
asin
string
Reference product ASIN. The tool finds niche segments associated with this ASIN.
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.
Empty result handling: When the response indicates no matching niche info (errcode 10000), explain that no niches matched the filters and suggest broadening ranges or verifying the ASIN.
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 ASIN/country).
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.
ASIN required: Every query must include an ASIN. The API will not return results without one.
No pagination/sorting: This endpoint returns a fixed number of niches via count (default 10); it does not expose page/pageSize/sort parameters. Use the keyword-based niche skill when sorting or deeper pagination is needed.
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 driven by a reference ASIN:
User Says
Scenario
"Which niches does this ASIN belong to"
ASIN-to-niche mapping
"Analyze the market for ASIN XXXXX"
ASIN-driven niche assessment
"How competitive is the niche this product is in"
Monopoly / brand concentration by ASIN
"Find low-competition niches for this ASIN"
Blue ocean segment filtering
"What's the new product success rate for this ASIN's niches"
New entrant viability
"Show me niche data for this product"
General niche exploration by ASIN
"What's the CPC / ad cost for this ASIN's niches"
Advertising cost analysis
"Brand concentration in this ASIN's market"
Brand dominance assessment
Not applicable -- Needs beyond ASIN-driven niche segment data:
Keyword-driven niche discovery (use the keyword-based niche skill instead)
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
Boundary judgment: When users say "market research" or "product opportunity" while holding a specific ASIN, if their intent focuses on evaluating the competitive landscape and demand potential of the niche segments that ASIN competes in, this skill applies. If they need keyword-driven discovery, ASIN-level sales estimates, or comprehensive business strategy, direct them to the appropriate tool.
