Nexscope Market Statistics

This skill helps fetch node-level market statistics for Amazon categories via Nexscope.

Core Concepts

Node statistics: Aggregated statistics for a specified category node, not returning complete product details.
TopN scope: topN determines the sample size of top products for statistics (default 10).
New product definition: newProduct specifies the number of recent months used to define "new product" (default 6).

How to Invoke

API Endpoint: POST /sellersprite/market/statistics (complete params/response/error codes in references/api.md)
Python Script: python scripts/amazon_market_statistics.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-sellersprite-market-statistics-<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.

Parameters

Parameter	Type	Required	Description
marketplace	string	Yes	Marketplace code, default `US`
nodeIdPath	string	Yes	Node ID path, e.g. `1064954:1069242:...`
month	string	No	`nearly` or `yyyyMM`
topN	integer	No	Top sample size, default 10
newProduct	integer	No	New product definition (months), default 6

Usage Example

{
  "marketplace": "US",
  "nodeIdPath": "172282:281407",
  "month": "nearly",
  "topN": 10,
  "newProduct": 6
}

Display Rules

Clearly display the statistical scope: topN, newProduct, time range.
Output key overview metrics first, then extended fields.
If the user does not provide nodeIdPath, guide them to provide a node path or do category location first.

Important Limitations

Required parameters: marketplace, nodeIdPath
nodeIdPath must be a valid node path
Month queries are limited by the third-party historical range
