Sorftime Product Detail

This skill guides you on how to query Amazon product detail and historical trend data by ASIN via Sorftime, helping Amazon sellers analyze product performance, pricing strategy, and competitive positioning.

Core Concepts

Sorftime Product Detail provides comprehensive product-level data by ASIN, with historical trend data going back to 2021. It covers sales volume & revenue trends, price & promotion tracking, multi-level BSR ranking history, and real-time profit analysis with FBA fee breakdown.

Key differentiator: This tool returns trend/time-series data for individual products. If you need to search/filter products across a category, brand, or seller, use the Sorftime Product Search skill instead.

Supported Marketplaces

US (United States), GB (United Kingdom), DE (Germany), FR (France), IN (India), CA (Canada), JP (Japan), ES (Spain), IT (Italy), MX (Mexico), AE (United Arab Emirates), AU (Australia), BR (Brazil), SA (Saudi Arabia)

Default marketplace is US. Use

us

when the user doesn't specify a marketplace.

Note: Sorftime uses lowercase codes (e.g.,

us

,

gb

,

de

), and UK is coded as

gb

(not

uk

).

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/sorftime_product_detail.py

directly to run queries.

How to Build Queries

The key parameters are

asin

and

marketplace

(both required), plus optional trend date range controls.

Principles for Building Queries

Always specify the marketplace: Use lowercase site codes, e.g.,
```
us
```
,
```
de
```
,
```
jp
```
Choose trend inclusion carefully: Default includes trends (last 15 days). Set
```
includeTrend: 2
```
if only basic product info is needed — this saves cost and speeds up response
Specify date range for historical analysis: Use
```
queryTrendStartDate
```
and
```
queryTrendEndDate
```
(yyyy-MM-dd) when users need trends beyond the default 15 days. Be aware this costs double
Batch ASINs when comparing: Up to 10 ASINs can be queried at once, comma-separated — use this for competitive comparison rather than calling one at a time

Query Examples for Common Scenarios

1. Quick product check (default 15-day trend)

asin: B00FLYWNYQ, marketplace: us

2. Long-range trend analysis (specify dates)

asin: B00FLYWNYQ, marketplace: us
queryTrendStartDate: 2025-01-01, queryTrendEndDate: 2025-03-31

3. Batch ASIN comparison

asin: B0088PUEPK,B00U26V4VQ,B0CVM8TXHP, marketplace: us

4. Product info only, no trends

asin: B0088PUEPK, marketplace: us, includeTrend: 2

5. BSR ranking history (German market)

asin: B00FLYWNYQ, marketplace: de
queryTrendStartDate: 2024-06-01, queryTrendEndDate: 2025-01-01

Trend Data Interpretation

Trend arrays use an interleaved format: even indices are dates, odd indices are values.

[20250101, 150, 20250102, 180, 20250103, 165, ...]
 ^date     ^val ^date     ^val ^date     ^val

Sales volume/revenue trends: value of
```
-1
```
means "cannot estimate" (e.g., category changed to Amazon Renewed)
Price trends: units are in local currency smallest unit (cents for USD);
```
-1
```
means no available price that day

BSR rank trends: for

bsrRankTrend

, format is

[{NodeId: xxx, Rank: [date, rank, ...]}]

per sub-category

Display Rules

Present data only: Show query results in clear tables without subjective business advice
Ranking clarification: When showing ranking data, remind users that lower values mean better rankings
Price unit awareness: Trend data uses smallest currency unit (cents for USD). Convert to standard currency when displaying to users
Sales estimation caveat: Values of
```
-1
```
in sales/revenue fields mean "cannot estimate" — explain this to the user rather than showing -1 directly
Trend visualization: When showing trend data, present key data points in a readable table rather than dumping raw arrays
Error handling: When a query fails, explain the reason based on the
```
msg
```
field and suggest adjusting query criteria

Important Limitations

Max 10 ASINs per query
Trend cost: Default returns last 15 days; querying > 15 days costs double
Non-structured data: Results do not support secondary analysis via
```
_dataQuery_executeDynamicQuery
```
Sales estimation: Products in non-standard categories (e.g., Amazon Renewed) may return -1 for sales fields

User Expression & Scenario Quick Reference

Applicable - Product detail and trend queries by ASIN:

User Says	Scenario
"查一下这个ASIN的销量走势"	Sales trend
"这个产品最近价格变化如何"	Price history
"帮我看看这个产品的利润空间"	Profit analysis
"这个ASIN的BSR排名趋势"	Ranking history
"对比一下这几个ASIN的数据"	Multi-ASIN comparison
"这个产品的FBA费用是多少"	FBA fee breakdown
"产品上架多久了，评分怎么样"	Basic product info

Not applicable - Needs beyond single-product detail:

Searching/filtering products across a category or brand (use Sorftime Product Search)
ABA search term ranking data (use ABA Data Explorer)
Advertising / PPC strategy
Product reviews content analysis
Patent or trademark checks

Boundary judgment: When users say "product analysis" or "competitor comparison", if it boils down to checking specific ASINs' detail data and trend curves, then this skill applies. If they're asking to discover or filter products across a market, it does not apply.
