Walmart 产品分析

Use Sorftime to find Walmart US products by a natural-language name or inspect one product's detail, historical trend, or daily sales-volume series.

Core Concepts

• Send exactly one operation per request. Never call all four operations as a default workflow.
• Use searchByName to discover related products, detail for the current product summary, trend for historical product changes, and salesVolume for dated sales rows.
• Every request uses a flat JSON body. searchByName requires name; the other operations require string productId. operation values are case-sensitive.
• A follow-up operation or a different date range is another paid call. Reuse the 24-hour cache for identical JSON.

Operation Routing

Read references/api.md before calling for exact date and pagination rules.

Parameter Guide

• Always treat productId as a string, even when it contains digits only.
• searchByName accepts a natural-language product name and returns up to 100 related products per page; pageIndex defaults to 1.
• salesVolume accepts optional queryDate and queryEndDate in yyyy-MM-dd. With neither, it returns the recent 30-day range; with only queryDate, the end defaults to the current day.
• pageIndex applies to searchByName and salesVolume, starts at 1, and defaults to 1.
• The current available historical range is controlled by Sorftime; do not promise a fixed earliest date.

调用方式

• API 端点：POST /sorftime/walmart/productAnalysis（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/sorftime_walmart_product_analysis.py '<JSON 参数>' [--inline]
• 成本约束：本工具会消耗算力；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。

输出策略（脚本默认行为）：

• 始终将完整响应写入 <cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-sorftime-walmart-product-analysis-<timestamp>.json（<cwd> 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；<session> 取自环境变量 SESSION_ID，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错）
• 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
• 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 total/costToken、最大列表字段的长度 + 前 3 条样本）
• 加 --inline 强制全量打印到 stdout（同样落盘）

读数据建议：先看摘要判断是否足够；需要具体字段时优先用 jq或ConvertFrom-Json 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。

解决认证和算力问题

发生以下异常情况时，采用 references/onboarding.md 引导解决问题：

• 未配置 API Key：环境变量未配置 LINKFOX_AGENT_API_KEY，也未配置 LINKFOXAGENT_API_KEY
• 响应 401 或 402 状态码
• 响应提示算力或余额不足：消息含“算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值”或类似含义

Usage Examples

python scripts/sorftime_walmart_product_analysis.py '{"operation":"searchByName","name":"wireless earbuds","pageIndex":1}'
python scripts/sorftime_walmart_product_analysis.py '{"operation":"detail","productId":"5169493923"}'
python scripts/sorftime_walmart_product_analysis.py '{"operation":"trend","productId":"5169493923"}'
python scripts/sorftime_walmart_product_analysis.py '{"operation":"salesVolume","productId":"5169493923","queryDate":"2026-07-01","queryEndDate":"2026-07-31","pageIndex":1}'

Display Rules

1. State the operation and supplied product name or product ID, and show returned requestConsumed, costCredit, and costToken. If _cache.hit=true, make clear that the cached values describe the original live request and no new production charge occurred.
2. For searchByName, label results as related products rather than exact matches and report the requested page.
3. For detail, present only fields returned by the ProductSummeryObject; do not infer missing attributes.
4. For trend, identify time fields and units from the response before summarizing changes.
5. For salesVolume, interpret rows as [date, sales, type]; type=2 marks yesterday's sales record.
6. Label estimates or observed values accurately; do not present them as guaranteed Walmart transactions.

Important Limitations

• This integration targets Walmart US only.
• The API accepts one product name or one product ID and one operation per call.
• Sorftime controls historical coverage and data availability.
• Pagination or a second operation creates another paid call and requires user authorization.
• searchByName is natural-language related-product discovery, not a multi-filter product database or category-market query.

User Expression & Scenario Quick Reference

Applicable: finding Walmart products from a natural-language product name, or queries centered on a known ProductId and its details, trend, or sales history.

Not applicable: category market research, keyword metrics/reverse lookup, or multi-condition product filtering.

Boundary judgment: Use searchByName only when the user needs related products from a name; use detail for a current snapshot, trend for historical attributes, and salesVolume only for dated sales rows.

算力消耗规则

按动态规则计费：单个 Sorftime Request 当前显示为 6 算力；多 Request 操作由网关按整单计算并取整，最终以入口脚本返回的 costCredit 为准，不要简单用 requestConsumed × 6 代替实际账单。

用户会因算力消耗而支付费用。不要未经确认补调另一 operation 或下一页。
