Nexscope Product Search

This skill guides you on how to search, filter, and analyze Amazon product data via the Nexscope product database, helping Amazon sellers make data-driven product selection decisions.

Core Concepts

Nexscope Product Search provides access to a comprehensive Amazon product database with rich filtering dimensions. It supports real-time data (last 30 days) as well as monthly historical snapshots for year-over-year and month-over-month comparisons. Supported marketplace codes are only: US, UK, DE, FR, JP, CA, IT, ES, MX, and IN (same as the gateway schema).

BSR (Best Sellers Rank): A lower BSR value means better sales performance in its category. A BSR of 1 means the top-selling product in that category. When a user says "BSR improved", it means the numeric value decreased; "BSR dropped" means the value increased.

Data snapshot: The dataSnapshotMonth parameter controls which time period to query. Use nearly (the default) for real-time last-30-day data, or a yyyyMM string (e.g., 202412) to query a historical monthly snapshot. This is useful for seasonal analysis and year-over-year comparison.

Match types for keywords: When searching by keyword, three matching strategies are available:

• Phrase match (default): Product titles must contain the keyword phrase
• Fuzzy match: Broader matching with related terms
• Exact match: Strict exact-string matching

desc	string	"true" for descending, "false" for ascending

Default sort: total_units descending.

Optional gateway / session fields

If the hosting environment supplies them, you may pass chatId, uid, requestId, and teamId as strings (see references/api.md). They are not required for ad-hoc script calls.

How to Invoke

• API Endpoint: POST /sellersprite/productSearch (complete params/response/error codes in references/api.md)
• Python Script: python scripts/amazon_broad_product_search.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-sellersprite-product-search-<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.

Usage Examples

1. Find high-sales products in a niche Search for products with keyword "yoga mat" in the US marketplace with monthly sales above 500 units, sorted by monthly sales descending.

{
  "keyword": "yoga mat",
  "marketplace": "US",
  "minUnits": 500,
  "order": {"field": "total_units", "desc": "true"}
}

2. Discover new product opportunities with low competition Find recently listed products (within 6 months) in the US with fewer than 50 ratings and monthly revenue above $5,000.

{
  "keyword": "desk organizer",
  "marketplace": "US",
  "listedWithinLastMonths": 6,
  "maxRatings": 50,
  "minRevenue": 5000,
  "order": {"field": "total_units", "desc": "true"}
}

3. Product improvement opportunity mining Find products with ratings between 3.8 and 4.3 (improvement sweet spot), monthly sales above 300, in a specific category.

{
  "keyword": "phone case",
  "marketplace": "US",
  "minRating": 3.8,
  "maxRating": 4.3,
  "minUnits": 300,
  "order": {"field": "total_units", "desc": "true"}
}

4. High-margin product screening Find products with gross margin above 40%, price between $15 and $50, at least 100 monthly sales.

{
  "marketplace": "US",
  "minProfit": 40,
  "minPrice": 15,
  "maxPrice": 50,
  "minUnits": 100,
  "order": {"field": "profit", "desc": "true"}
}

5. Seasonal year-over-year comparison Query last year's December snapshot data to compare with current data for seasonal product planning.

{
  "keyword": "christmas lights",
  "marketplace": "US",
  "dataSnapshotMonth": "202412",
  "minUnits": 200,
  "order": {"field": "total_units", "desc": "true"}
}

6. Chinese seller competitive landscape Find FBA-fulfilled products from Chinese sellers in a category with high monthly sales.

{
  "keyword": "bluetooth speaker",
  "marketplace": "US",
  "sellerNation": "CN",
  "fulfillment": "FBA",
  "minUnits": 200,
  "order": {"field": "total_units", "desc": "true"}
}

7. Best Seller & Amazon's Choice badge holders Find products carrying the Best Seller badge with strong sales performance.

{
  "keyword": "water bottle",
  "marketplace": "US",
  "badgeBestSeller": "Y",
  "order": {"field": "total_units", "desc": "true"}
}

8. Fast-growing products by sales growth rate Find products with monthly sales growth rate above 50%.

{
  "keyword": "standing desk",
  "marketplace": "US",
  "minUnitsGrowthRate": 50,
  "order": {"field": "total_units_growth", "desc": "true"}
}

Display Rules

1. Present data clearly: Show query results in well-structured tables. Key columns to prioritize: ASIN, title, price, monthly sales, monthly revenue, BSR rank, rating, ratings count, gross margin, fulfillment type
2. BSR clarification: When showing BSR data, remind users that lower values mean better rankings
3. Gross margin note: Gross margin values are percentages. Remind users this is an estimate based on price minus FBA fees and estimated costs
4. Pagination awareness: When the total count exceeds the returned page size, inform the user of the total result count and suggest adjusting page or size parameters to see more results
5. Snapshot labeling: When displaying historical snapshot data, clearly label the data period (e.g., "Data from December 2024 snapshot") to avoid confusion with real-time data
6. Error handling: When a query fails, explain the reason based on the message field and suggest adjusting query criteria
7. Weight unit reminder: When the user provides weight filters without specifying a unit, ask them to confirm the weight unit (g, kg, oz, or lb) before proceeding
8. Keyword translation: When the user provides keywords in a language different from the target marketplace, translate the keyword to the appropriate language and note the translation

Important Limitations

• Result cap: Each page returns a maximum of 100 records (size parameter max is 100)
• Historical snapshots: Only past monthly snapshots are available; future dates are not supported
• Weight unit required: If any weight filter is used, the weightUnit must also be provided
• Subcategory BSR: The subcategory BSR rank filters only work when filterSubNode is set to true
• Listed time enum only: The listedWithinLastMonths parameter only accepts specific values: 1, 3, 6, 12, or 24
• Child ASIN 30-day sales filters: minAmzUnit / maxAmzUnit apply only to last-30-day style queries (typically dataSnapshotMonth: "nearly"); do not rely on them for historical yyyyMM snapshots

User Expression & Scenario Quick Reference

Applicable -- Product-level data queries on Amazon:

User Says	Scenario
"Find products with high sales in XX category"	Niche product search
"Show me low-competition products", "new product opportunities"	Blue ocean product discovery
"Which products have high margins"	Profitability screening
"Products with rising sales", "trending products"	Growth trend detection
"What are Chinese sellers selling well"	Competitive landscape analysis
"Recently launched products doing well"	New product tracking
"Products with bad reviews but good sales"	Product improvement opportunities
"Compare this category with last year"	Seasonal / YoY analysis
"FBA products under $30 with 1000+ sales"	Multi-criteria product filtering
"Best sellers in XX category"	Badge-based product discovery

Not applicable -- Needs beyond product-level search data:

• ABA search term / keyword analysis (use ABA Data Explorer instead)
• Advertising / PPC campaign data
• Product review text analysis
• Listing copywriting or optimization
• Supplier sourcing or manufacturing costs
• Logistics and inventory planning

Boundary judgment: When users say "product research" or "market analysis", if it boils down to filtering Amazon products by sales, price, BSR, ratings, and other product attributes, then this skill applies. If they are asking about keyword search volume, search term rankings, or click/conversion share data, the ABA Data Explorer skill is more appropriate.
