Ecommerce Amazon Niche Info Skill for Claude

Nexscope Niche Market Info

This skill guides you on how to query and analyze Amazon niche market data via the Nexscope data service, helping Amazon sellers gain deep insights into specific niche markets including competition, pricing, reviews, and growth trends.

How to Invoke

• API Endpoint: POST /jiimore/getNicheInfo (complete params/response/error codes in references/api.md)
• Python Script: python scripts/amazon_niche_info.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-jiimore-get-niche-info-<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.

Core Concepts

A niche market in Nexscope 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.

Parameter Guide

| Parameter | Type | Required | Description |

|-----------|------|----------|-------------|

| nicheId | string | Yes | The niche market ID to query. Maximum 1000 characters. Only one ID per request. |

| countryCode | string | No | Marketplace code. Allowed values: US, JP, DE. Defaults to US. |

How to Use Parameters

• nicheId is mandatory: The user must provide or you must identify the niche market ID. This is a string identifier for a specific Amazon niche segment.
• countryCode defaults to US: Only specify a different value when the user explicitly mentions Japan (JP) or Germany (DE).
• Single ID per call: This tool only supports one niche ID per request. If the user wants to compare multiple niches, make separate calls.

Usage Examples

1. Basic niche market lookup (US)

Query niche market data for a given niche ID in the US marketplace:

nicheId: "12345678"
countryCode: "US"

2. Query a niche in the Japan marketplace

nicheId: "87654321"
countryCode: "JP"

3. Query a niche in the Germany marketplace

nicheId: "11223344"
countryCode: "DE"

• Units sold (weekly/quarterly)

Competition Landscape

Display Rules

• Present data clearly: Show query results in well-structured tables or grouped sections without subjective business advice unless specifically requested.
• Trend comparison: When the response includes current, 90-day-ago, and 360-day-ago data points, present them side-by-side so users can easily spot trends.
• Percentage formatting: Display share and rate values as percentages (e.g., 0.35 as 35.0%).
• Review insights: If positive/negative customer review insights are present, list them as bullet points.
• Image display: If referenceAsinImageUrl is present, display or link to the niche reference image.
• Error handling: When a query fails, explain the reason based on the response and suggest checking the niche ID or country code.

Important Limitations

• Single ID only: Only one niche ID can be queried per request. Batch queries are not supported.
• Three marketplaces: Only US, JP, and DE are supported.
• Niche ID required: The user must supply the niche ID; this tool cannot search for niches by keyword or category.
