# 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 Usage

This tool calls the LinkFox tool gateway API. See `references/api.md` for calling conventions, request parameters, and response structure. You can also execute `scripts/jiimore_page_asins_by_asin.py` directly to run queries.

## Usage Examples

**1. Basic competitor lookup by ASIN**
Find competing products for a reference ASIN in the US market:
```json
{
  "asin": "B0GC4RPX79",
  "countryCode": "US",
  "sortField": "purchasedClicksT360",
  "sortType": "desc"
}
```

**2. High-conversion competitors**
Find competitors with composite conversion rate above 15%:
```json
{
  "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:
```json
{
  "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:
```json
{
  "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:
```json
{
  "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:
```json
{
  "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:
```json
{
  "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 & 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.

## 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_page_asins_by_asin.py --out-dir <DIR> '<params>'
python scripts/response_io.py read <file> --fields "<paths>"   # or --path "<JMESPath>"
```

> 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`.
