Nexscope -- Keyword Historical Search Volume
This skill queries the historical exact search volume for Amazon keywords via the Nexscope data source, returning weekly search volume data points over a specified date range across 10 Amazon marketplaces.
Core Concepts
The Nexscope Keyword Historical Search Volume tool provides weekly granularity exact match search volume historical data for Amazon marketplace keywords. Sellers can query search volume changes within a specified time range to determine:
- Seasonal patterns: Which months are peak/off-season for a keyword
- Trend direction: Whether search volume is consistently rising, falling, or stable
- Volatility: Assess the stability of market demand
- Holiday effects: Search volume spikes around major promotions and holidays
Data granularity: Each record represents a 7-day period, including the exact match search volume estimate for that week.

How to Invoke
- API Endpoint:
POST /tool-jungle-scout/keywords/historical-search-volume (complete params/response/error codes in references/api.md)
- Python Script:
python scripts/amazon_keyword_search_history.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-junglescout-keyword-history-<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.
How to Build Queries
All four parameters are required: marketplace, keyword, startDate, endDate.
Principles for Building API Calls
- Marketplace mapping: "US marketplace" ->
us, "Japan marketplace" -> jp, "Germany marketplace" -> de; default to us when unspecified
- Date format: Must be
YYYY-MM-DD, e.g. 2025-01-05
- Time span:
startDate to endDate maximum 366 days; split into multiple requests if exceeding this
- Keyword: Pass the user-provided keyword as-is (lowercase English preferred)
- Common time calculations:
- "Past 3 months" -> endDate = today, startDate = ~90 days ago
- "Full last year" ->
2025-01-01 to 2025-12-31
- "Peak season" -> determine by category, e.g. Q4 =
10-01 to 12-31
Common Query Scenarios
1. View keyword search trend for the past half year
{
"marketplace": "us",
"keyword": "yoga mat",
"startDate": "2025-10-01",
"endDate": "2026-03-31"
}
2. Determine keyword seasonality (full year data)
{
"marketplace": "us",
"keyword": "christmas decorations",
"startDate": "2025-01-01",
"endDate": "2025-12-31"
}
3. Compare peak-season vs off-season search volume
Make two separate calls:
- Off-season:
startDate=2025-02-01, endDate=2025-04-30
- Peak season:
startDate=2025-10-01, endDate=2025-12-31
4. Multi-marketplace comparison
Query the same keyword across different marketplaces (e.g., us, de, jp) and compare search volume scale across markets.
5. Verify whether market demand is growing
{
"marketplace": "de",
"keyword": "luftreiniger",
"startDate": "2025-04-01",
"endDate": "2026-03-31"
}
Display Rules
- Trend visualization priority: Recommend displaying search volume changes as a timeline/line chart, with date periods on the X-axis and search volume on the Y-axis
- Table support: Also provide a data table for precise reference, columns including: Period Start Date, Period End Date, Search Volume
- Trend summary: Briefly summarize the trend direction after the data (rising/falling/stable/cyclical), highlighting peak and trough periods
- Peak annotation: Highlight the periods with the highest and lowest search volume for quick peak/off-season identification
- Error handling: When a query fails, explain the reason based on the error response and suggest adjusting parameters (e.g., date range exceeds 366 days)
Important Limitations
- Time span cap: Single query
startDate to endDate maximum 366 days; split into multiple queries if exceeding
- Data granularity: Weekly (7 days per data point), not daily
- Search volume type: Exact match search volume, not broad match
- All parameters required:
marketplace, keyword, startDate, endDate -- all are mandatory
User Expression & Scenario Quick Reference
Applicable -- Keyword search volume historical trend analysis:
| User Says | Scenario |
|---|
| "How has this keyword's search volume changed" | Search volume trend query |
| "Does this category have seasonality" | Full year data for seasonal pattern analysis |
| "Is search volume rising or falling recently" | Recent trend assessment |
| "When is the peak season" | Peak period identification |
| "What was the search volume in Q4 last year" | Specified time period search volume query |
| "How popular is this keyword on the Germany marketplace" | Non-US marketplace search volume query |
| "Compare search volume between two time periods" | Peak/off-season or year-over-year comparison |
Not applicable -- Beyond keyword historical search volume scope:
- Keyword suggestions/expansion (requires keyword mining tools)
- Real-time/current search volume ranking (requires ABA or Nexscope tools)
- Keyword competition, CPC bids
- Product sales, listing analysis
- Non-Amazon platform search volume
Boundary judgment: When users say "search volume", "keyword popularity", or "market demand trends", if they specifically want to see how a keyword's search volume changes over a period of time (historical trend), this skill applies. If they want the current ranking or a list of trending keywords, it does not apply.
