Jiimore Niche Competitor by ASIN

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).

API Invocation

• API Endpoint: POST /jiimore/pageAsinsByAsin (see references/api.md for full parameters/responses/error codes)
• Python Script: python scripts/amazon_related_asins.py '<JSON params>' [--inline]
• Cost Constraints: This tool consumes credits. The same parameter combination in the same session is only called once by default, with 24h local caching in the script. Failed or empty results should not trigger automatic retries with different keywords, pagination, or postal codes. Inform the user before making additional queries that will incur extra costs.

Output Strategy (default script behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-jiimore-page-asins-by-asin-<timestamp>.json (<cwd> is the working directory at script execution time, which in Claude Code is the current project directory; <session> is taken from the SESSION_ID environment variable, auto-grouped by user task; do not write to /tmp, error out if the current directory is not writable)
• Response body less than or equal to 8 KB: print the full JSON to stdout after saving to disk
• Response body greater than 8 KB: after saving, stdout prints only a summary (top-level fields, common counts like total/costToken, length of the largest list field + first 3 samples)
• Add --inline to force full output to stdout (still saves to disk)

Data Reading Tips: Check the summary first to determine if it is sufficient. When specific fields are needed, use jq or ConvertFrom-Json to extract from the saved JSON file on demand, avoiding loading the entire JSON into context.

Authentication

Set the NEXSCOPE_API_KEY environment variable. If authentication fails (401/402) or you see insufficient balance errors, visit https://www.nexscope.ai/help/skills-external-access?co-from=skillNS to get an API Key or top up credits.

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"
}

3. New product opportunities Find recently launched competitors (within 3 months) with high click growth:

{
  "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",
  "sortType": "desc"
}

5. High-click low-review competitors (potential weak spots) Find competitors with monthly clicks above 2000 but fewer than 100 reviews:

{
  "asin": "B0GC4RPX79",
  "countryCode": "US",
  "clickCountT30Min": 2000,
  "totalReviewsMax": 100,
  "sortField": "clickCountT30",
  "sortType": "desc"
}

6. Japanese market competitor analysis Explore competitors in the Japanese market sorted by rating:

{
  "asin": "B0GC4RPX79",
  "countryCode": "JP",
  "sortField": "customerRating",
  "sortType": "desc"
}

7. Chinese sellers in the same niche Filter competitors by seller country (China) with high sales volume:

{
  "asin": "B0GC4RPX79",
  "countryCode": "US",
  "sellerCountry": "CN",
  "salesVolumeT360Min": 1000,
  "sortField": "purchasedClicksT360",
  "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 ASIN, product title, price, customer rating, click conversion rate (composite), click counts, total reviews, and gross profit margin as primary columns.
3. Show niche context: When the niches field is present, display the top niche titles and demand scores to give context about which market segments the product competes in.
4. Trends visualization: When trends data is available, summarize the 90-day trend direction (rising/falling/stable) for key metrics like clicks and pricing.
5. Pagination guidance: When total exceeds the current page size, inform the user of the total count and suggest fetching additional pages if needed.
6. 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).
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.
• 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 yyyyMMdd000000 format.

User Expression and 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.
