# Wenmai Keepa Product History

## Purpose
Use this Skill to fetch Keepa 历史数据 data through Wenmai standard API.

The Skill calls exactly one fixed standard API endpoint:

- Endpoint: `POST /wmapi/v1/keepa/get-keepa-product-history`
- Auth: Header `secret-key: $WENMAI_API_KEY`
- Script: `scripts/keepa_product_history.py`

## How To Run

请参考 https://skill.wenmai-ai.com/wenmaiskills/use_guide.html 获取 `secret-key`；额度或余额不足时，按该指南完成充值。运行脚本前，把复制的 key 导出为 `WENMAI_API_KEY`（或 `WENMAI_SECRET_KEY`）。

```bash
export WENMAI_API_KEY=sk-...
python3 scripts/keepa_product_history.py '{"domain": 1, "asin": "B08GHW4TBS", "stats": 90, "history": true, "rating": true}'
```

The script prints the raw Wenmai API response as formatted JSON. Read `references/api.md` when you need parameter details, field meanings, or the exact API payload.

## Parameter Rules

Required top-level fields: `asin`, `domain`.

Default marketplace assumptions: use Amazon US / `US` / domain `1` unless the user specifies another marketplace. Preserve the user's requested time window, ASIN list, keyword, filters, pagination, and sort order.

## Response Rules

Present the returned data in compact tables when the user asks for inspection or comparison. For long arrays, summarize the most decision-relevant rows first, then offer to continue with more rows. Keep raw numbers traceable to the response fields.

If the API response contains an `error` or a non-`OK` `code`, report the message and suggest parameter corrections. Never invent missing data.
