This skill guides you on how to query and analyze Amazon niche market data via the Jiimore data service, helping Amazon sellers gain deep insights into specific niche markets including competition, pricing, reviews, and growth trends.
How to call
- API endpoint：
POST /jiimore/getNicheInfo(For full parameters/responses/error codes, seereferences/api.md） - Python script：
python scripts/jiimore_get_niche_info.py '<JSON 参数>' [--inline] - Cost constraints: This tool consumes compute; by default, the same parameter combination is called only once per session, and the script has a 24h local cache. On failure/empty results, do not automatically try different keywords, paginate, or change the zip code in repeated probing; if further retrieval is needed, first explain to the user that it will incur additional consumption.
Output strategy (default script behavior)：
- Alwayswrite the full response to
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-jiimore-get-niche-info-<timestamp>.json（<cwd>is the working directory when the script runs, which in Claude Code is the current project directory;<session>is taken from the environment variableSESSION_ID, automatically aggregated according to the user's task;writing to /tmp is prohibited, and if the current directory is not writable, report an error) - Response body ≤ 8 KB: after saving to disk, print the full JSON to stdout
- Response body > 8 KB: after saving to disk, stdout outputs only a summary (top-level fields, common counts such as
total/costToken, the length of the largest list field + the first 3 samples) - Add
--inlineto force full printing to stdout (also saved to disk)
Data reading suggestions: First look at the summary to determine whether it is sufficient; when specific fields are needed, prefer to use jqorConvertFrom-Json to extract on demand from the saved json file, avoiding putting the entire JSON into the context.
Resolve authentication and compute issues
When the following abnormal situations occur, use references/onboarding.md to guide resolution:
Abnormal situations
- API Key not configured: The environment variable is not configured
LINKFOX_AGENT_API_KEY, andLINKFOXAGENT_API_KEY。 - Response 401 or 402 status code
- Response indicates insufficient compute or balance: The message contains "insufficient compute balance/insufficient billing/insufficient balance/quota exceeded/insufficient balance/package expired/recharge required/please recharge", or content with a similar meaning.
Core Concepts
A niche market in Jiimore represents a fine-grained product segment on Amazon. Each niche is identified by a unique nicheId. This tool retrieves comprehensive market intelligence for a single niche at a time, covering:
- Market overview: niche title, demand score, product count, brand count, selling partner count
- Pricing: average price, minimum price, maximum price
- Search & conversion: weekly/quarterly search volume, search volume growth, search conversion rate, click-to-sale conversion rate, units sold
- Competition concentration: top 5 / top 20 product and brand click share (current, 90-day, 360-day snapshots)
- Product launches: new products launched, successful launches across 90-day / 180-day / 360-day windows
- Inventory health: average out-of-stock rate over time
- Seller maturity: average brand age, average selling partner age
- Review insights: average review rating, average review count, positive and negative customer review insights
- Advertising: ACOS (advertising cost of sales), sponsored products percentage
- Profitability: profit margin > 50% SKU ratio, break-even ratio, return rate
Supported marketplaces: US (United States), JP (Japan), DE (Germany). Default is US.
