Jungle Scout — ASIN Sales Estimates
This skill queries daily sales estimates and last known price for a given Amazon ASIN via the Jungle Scout data source, returning day-level data points over a specified date range across 10 Amazon marketplaces.
Core Concepts
The Jungle Scout ASIN Sales Estimate tool provides daily estimated sales volume and latest known price for individual ASINs across Amazon marketplaces. Sellers can query sales changes over a specified time range to:
- Monitor competitor sales: Understand competitors' daily order volume and evaluate their market share
- Validate product selection opportunities: Verify whether product demand is sufficient using actual sales data
- Track seasonal patterns: Observe sales fluctuations of products in different months to identify peak and off-peak seasons
- Evaluate pricing impact: Assist in pricing decisions by combining the relationship between price and sales changes
- Track new product performance: Monitor the sales growth curve of new products after they are launched
Data Granularity: Each record represents 1 day, including the estimated number of units sold and the latest known price (USD) for that day.

Supported Marketplaces
10 Amazon marketplaces:
(United States),
(United Kingdom),
(Germany),
(India),
(Canada),
(France),
(Italy),
(Spain),
(Mexico),
(Japan). The default marketplace is
us. If the user does not specify a marketplace,
will be used.
API Usage
This tool calls the LinkFox tool gateway API. See
for calling conventions, request parameters, and response structure. You can also execute
scripts/junglescout_sales_estimates.py
directly to run queries.
How to Build Queries
All four parameters are
required:

.
Principles for Building API Calls
- Marketplace Mapping: When users say "US marketplace" → , "Japan marketplace" → , "Germany marketplace" → ; default to if not specified
- Date Format: Must be , e.g.,
- endDate Restriction: must be earlier than the current date (cannot include today or future dates)
- ASIN Format: Standard Amazon ASIN, usually starting with B0, 10 characters long
- Common Time Calculations:
- "Last 30 days" → set endDate to yesterday, startDate to 30 days ago
- "Last month" → from the 1st to the last day of the previous month
- "Q3 vs Q4" → make two separate calls, querying July-September and October-December respectively
Common Query Scenarios
1. View Competitors' Sales in the Last 30 Days
json
{
"marketplace": "us",
"asin": "B0CXXX1234",
"startDate": "2026-03-18",
"endDate": "2026-04-16"
}
2. Compare Q3 and Q4 Sales Performance
Make two separate calls:
3. Validate Product Selection Opportunities - View Annual Product Sales
json
{
"marketplace": "us",
"asin": "B0CXXX5678",
"startDate": "2025-04-01",
"endDate": "2026-03-31"
}
4. Track New Product Launch Performance
json
{
"marketplace": "de",
"asin": "B0DYYY9999",
"startDate": "2026-01-15",
"endDate": "2026-04-15"
}
5. Monitor Sales Changes During Promotions (e.g., Prime Day)
json
{
"marketplace": "us",
"asin": "B0CXXX1234",
"startDate": "2025-07-01",
"endDate": "2025-07-21"
}
Display Rules
- Line Chart Priority: It is recommended to display daily sales changes with a line chart, with the horizontal axis as the date and the vertical axis as the daily estimated sales volume; if price data is available, a second Y-axis can be overlaid to show price trends
- Table Support: Provide a data table for precise reference at the same time, including columns: Date, Estimated Sales Volume, Latest Known Price
- Summary Statistics: After the data, summarize key indicators - total sales volume, average daily sales volume, estimated total revenue (total sales volume × average price)
- Trend Summary: Briefly summarize the trend direction (rising/falling/stable/periodic fluctuations), and mark the dates of sales peaks and troughs
- Error Handling: When a query fails, explain the reason based on the error response and suggest adjusting parameters (e.g., endDate cannot include today or future dates)
Important Limitations
- endDate Cannot Include Today: must be earlier than the current date; sales data for today or the future cannot be queried
- Single ASIN per Call: Only one ASIN can be queried per call; comparing multiple ASINs requires separate calls
- All Parameters Required: , , , are all mandatory
- Price in USD: is in USD, not local currency
User Expression & Scenario Quick Reference
Applicable Scenarios - ASIN Sales Estimation and Sales Trend Analysis:
| User Says | Scenario |
|---|
| "How many units does this ASIN sell per day?" | Query recent daily sales estimates |
| "How have competitors been selling recently?" | Monitor competitors' sales in the last 30 days |
| "Does this product have seasonal trends?" | Determine seasonal patterns using annual sales data |
| "Help me check the sales trend of this product" | Sales trend over a specified time period |
| "How were sales during the Q4 peak season?" | Query sales for a specific quarter |
| "Is this product worth selling?" | Validate product selection opportunities through historical sales data |
| "How many units were sold during the promotion?" | Monitor sales during promotional events |
Not Applicable Scenarios - Beyond the Scope of ASIN Sales Estimation:
- Keyword search volume (requires keyword historical search volume tool)
- BSR ranking history (requires BSR tracking tool)
- Category overall sales/market size
- Sales data from non-Amazon platforms
- Real-time/current sales (data has a lag, does not include today)
Boundary Judgment: When users mention "sales volume", "daily sales", or "how many units sold", if they want to view daily estimated sales for a specific ASIN over a time range, this skill applies. If they want keyword search volume, category rankings, or real-time live sales, it does not apply.
