This skill guides you on how to query and filter Amazon competing products in the same niche segments as a reference ASIN, helping Amazon sellers discover potential competitors and evaluate opportunities using metrics such as click conversion rate, composite conversion rate, click volume, sales volume, reviews, price, FBA fees, and gross profit margin.
Core Concepts
Given a reference ASIN, the tool mines competing ASINs that share the same niche segments on Amazon and returns a paginated list with rich metrics: click conversion rate, composite conversion rate, click counts (7-day/30-day/90-day), sales volume, pricing, FBA fees, gross profit margin, customer rating, and 90-day trend data. Data is available for US, JP, and DE marketplaces only.
ASIN is required: Every query must include a reference asin. The tool finds products that share the same niche segments as this ASIN and returns them with detailed metrics.
Percentage fields: Several parameters use a 0-1 decimal range representing 0%-100%. When displaying these values to users, convert them to percentages (e.g., 0.15 -> 15%).
Date format: Launch date parameters use the format yyyyMMdd000000 (e.g., 20240101000000 for January 1, 2024).

How to call
- API endpoint：
POST /jiimore/pageAsinsByAsin(for full parameters/responses/error codes seereferences/api.md） - Python script：
python scripts/jiimore_page_asins_by_asin.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 switch keywords, page through, or change zip codes to probe repeatedly; if you need to continue searching, first explain to the user that additional consumption will be incurred.
Output strategy (script default behavior)：
- Alwayswrite the full response to
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-jiimore-page-asins-by-asin-<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 by user task;writing to /tmp is prohibited, 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 judge whether it is sufficient; when specific fields are needed, prefer using jqorConvertFrom-Json to extract on demand from the saved json file, avoiding bringing the entire JSON into 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.
Usage Examples
1. Basic competitor lookup by ASIN Find competing products for a reference ASIN in the US market:
{
"asin": "B0GC4RPX79",
"countryCode": "US",
"sortField": "purchasedClicksT360",
"sortType": "desc"
}
2. High-conversion competitors Find competitors with composite conversion rate above 15%:
{
"asin": "B0GC4RPX79",
"countryCode": "US",
"clickConversionRateCompositeMin": 0.15,
"sortField": "clickConversionRateComposite",
"sortType": "desc"
}

{
"asin": "B0GC4RPX79",
"countryCode": "US",
"launchDateMin": "20240101000000",
"clickCountGrowthT7Min": 0.1,
"sortField": "clickCountGrowthT7",
"sortType": "desc"
}
4. Price-range filtered competitors Find competitors priced between $20 and $50 with good gross margins:
{
"asin": "B0GC4RPX79",
"countryCode": "US",
"priceMin": 20,
"priceMax": 50,
"grossProfitMarginMin": 0.3,
"sortField": "gpm",

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 ASIN, product title, price, customer rating, click conversion rate (composite), click counts, total reviews, and gross profit margin as primary columns.
- Show niche context: When the
nichesfield is present, display the top niche titles and demand scores to give context about which market segments the product competes in. - Trends visualization: When
trendsdata is available, summarize the 90-day trend direction (rising/falling/stable) for key metrics like clicks and pricing. - Pagination guidance: When
totalexceeds 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 ASIN).
- 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 a reference ASIN. 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.
- Date format: Launch date parameters must use
yyyyMMdd000000format.
User Expression & Scenario Quick Reference
Applicable -- Finding competing products based on a reference ASIN:
| User Says | Scenario |
|---|---|
| "Find competitors for ASIN B0GC4RPX79" | Direct competitor lookup |
| "What products compete with this ASIN" | Same-niche competitor exploration |
| "Show me similar products in the same niche" | Niche competitor discovery |
| "High-conversion competitors for my product" | Conversion-based competitor filtering |
| "New products competing in my niche" | New entrant identification |
| "Which Chinese sellers compete with this ASIN" | Seller-origin based filtering |
| "Find low-review high-click products like mine" | Opportunity gap analysis |
| "Competitor pricing analysis for ASIN XX" | Price-focused competitor analysis |
Not applicable -- Needs beyond ASIN-based same-niche competitor discovery:
- Keyword-level niche market analysis (use Jiimore Niche Info by Keyword instead)
- Individual ASIN revenue or profit estimation
- ABA search term data / keyword research
- Advertising campaign management or bid optimization
- Product review analysis or listing optimization
- Supplier sourcing or logistics planning
Boundary judgment: When users say "competitor analysis" or "similar products," if their intent focuses on finding products that compete in the same niche as a specific ASIN, this skill applies. If they want keyword-level market segment data, direct them to Jiimore Niche Info by Keyword. If they need detailed product data for a single ASIN, direct them to Amazon Product Detail.
