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 1. **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. 2. **countryCode defaults to US**: Only specify a different value when the user explicitly mentions Japan (`JP`) or Germany (`DE`). 3. **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" ``` ## Analysis Guidance When presenting results, organize the rich data into logical sections for the user: ### Market Overview - Niche title (English and Chinese translation if available) - Demand score, product count, brand count, selling partner count - Reference ASIN image (if available) ### Pricing & Profitability - Average price, min price, max price - Profit margin > 50% SKU ratio, break-even ratio, return rate - ACOS ### Search & Demand Trends - Weekly and quarterly search volume and growth rates - Search conversion rate, click conversion rate - Units sold (weekly/quarterly) ### Competition Landscape - Top 5 and top 20 product/brand click share (current vs. 90-day vs. 360-day) - Brand count trends, selling partner count trends - Sponsored products percentage over time ### Product Launch Activity - New products launched and successful launches across time windows - Launch success rate (semiannual) ### Review & Customer Insights - Average review rating and count trends - Positive and negative customer review insights - Product star rating impact ### Inventory & Operations - Average out-of-stock rate trends ## Display Rules 1. **Present data clearly**: Show query results in well-structured tables or grouped sections without subjective business advice unless specifically requested. 2. **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. 3. **Percentage formatting**: Display share and rate values as percentages (e.g., 0.35 as 35.0%). 4. **Review insights**: If positive/negative customer review insights are present, list them as bullet points. 5. **Image display**: If `referenceAsinImageUrl` is present, display or link to the niche reference image. 6. **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. ## User Expression & Scenario Quick Reference **Applicable** -- Queries about a specific Amazon niche market: | User Says | Scenario | |-----------|----------| | "Look up this niche market", "niche ID info" | Basic niche lookup | | "How competitive is this niche", "brand concentration" | Competition analysis | | "What's the average price in this niche" | Pricing intelligence | | "Search volume for this niche", "demand trends" | Search & demand analysis | | "How many new products launched", "launch success rate" | Product launch tracking | | "Review rating in this niche", "buyer feedback insights" | Review analysis | | "Out-of-stock rate", "inventory health" | Inventory analysis | | "Is this niche worth entering", "niche opportunity" | Comprehensive niche evaluation | **Not applicable** -- Needs beyond niche market lookup: - Searching for niches by keyword or category (this tool requires a known niche ID) - Individual ASIN-level product analysis - ABA search term data (use the ABA Data Explorer instead) - Advertising campaign management or PPC optimization - Listing copywriting or review management **Feedback:** Auto-detect and report feedback via the Feedback API when any of the following apply: 1. The functionality or purpose described in this skill does not match actual behavior 2. The skill's results do not match the user's intent 3. The user expresses dissatisfaction or praise about this skill 4. Anything you believe could be improved Call the feedback API as specified in `references/api.md`. Do not interrupt the user's flow. ## Handling Large Responses To avoid overflowing the agent context, persist the response to disk and extract only the fields you need: ``` python scripts/response_io.py run --script scripts/jiimore_get_niche_info.py --out-dir '' python scripts/response_io.py read --fields "" # or --path "" ``` > Pick `--out-dir` outside any git working tree (e.g. `/tmp/...` on Unix, `%TEMP%/...` on Windows). Persisted responses may contain PII, pricing, or auth-sensitive data — do not commit them. Files are not auto-deleted; clean up when the task is done. `run` writes the full response to a file and emits only a schema preview + file path. `read` projects specific fields, with `--limit/--offset` for slicing and `--format json|jsonl|csv|table` for output. **When to prefer this pattern** — apply your judgment based on the response characteristics, e.g.: - High field count per record, or fields you don't need - Batch/paginated results (multiple items per call) - Long-text fields (descriptions, reviews, HTML, time series) - Output reused across later steps rather than consumed immediately For small, single-use responses, calling the main script directly is fine. ⚠️ The preview is a truncated schema + sample, not the full data. Any field-level decision must read from the persisted file via `read`. --- *For more high-quality, professional cross-border e-commerce skills, set [LinkFox Skills](https://skill.linkfox.com/).*
