What This Skill Does

通过亚马逊 SP-API Product Pricing 接口查询商品定价、竞争定价、Listing/Item Offers、Featured Offer Expected Price (FOEP) 及竞争摘要,支持单条和批量查询。

Replaces manually scraping Amazon product pages or building custom SP-API pricing integrations by providing a unified CLI and proxy endpoint for all pricing-related APIs.

When to Use It

  • 查询指定 ASIN 或 SKU 的当前售价和最低报价
  • 批量获取多个 ASIN 的竞争定价和 Featured Offer 预期价格
  • 分析 Listing 或商品的 Offers 分布以辅助定价决策
  • 获取竞争摘要(Competitive Summary)了解市场定价趋势
  • 在自动化定价策略中集成 FOEP(Featured Offer Expected Price)数据

Amazon 店铺 Product Pricing

本 skill 与 linkfox-amazon-store-authlinkfox-amazon-store-reportlinkfox-amazon-store-listings 同属 Amazon Store 系列:依赖 linkfox-amazon-store-auth 选店(sellerId+region);直接 POST /spApi/developerProxy 传入 sellerId+region,由服务端解析 token(勿传 amzAccessToken,除非兼容旧调用)。转发上游 GETPOST

调用方式

  • API 端点POST /spApi/developerProxy(不同操作通过请求体区分;完整参数/响应/错误码见 references/api.md
  • Python 脚本python scripts/<脚本名>.py '<JSON 参数>' [--inline](可用脚本见上文脚本一览)
  • 成本约束:本工具会消耗积分;失败/空结果不得自动换关键词、翻页或连续试探;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/<skill-name>-<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)
  • --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 jqConvertFrom-JsonConvertFrom-Json 从保存的 json 文件按需抽取,避免整份 JSON 进入上下文。

解决认证和积分问题

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

异常情况

  • 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
  • 响应提示积分或余额不足:消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值",或类似含义的内容。

Prerequisites(必须先读)

本 skill 依赖 linkfox-amazon-store-auth

  1. 运行 python scripts/check_auth_dependency.py;若 exit code 42 且 stderr 含 DEPENDENCY_MISSING:,请先安装 linkfox-amazon-store-auth
  2. 不要在本 skill 内绕过依赖实现授权或令牌逻辑。

getCompetitiveSummarybatches/products/pricing/2022-05-01/items/competitiveSummary,POSTpost_competitive_summary_batch.py

批量脚本(post_*_batch.py)在默认模式下会按 Amazon 要求组装子请求;高级用法可设 useAmazonRequestShape: true,直接传 requests 为官方原始数组(仍受条数上限约束)。共享逻辑见 scripts/_spapi_pricing_common.py(仅供同目录脚本 import,非独立 CLI)。


Quick Parameters(摘要)

  • getPricing / getCompetitivePricingsellerIdregionmarketplaceId(或 marketplaceIds 取首)、itemTypeasinsskus(≤20);getPricing 另有 itemConditionofferType;getCompetitivePricing 另有 customerType
  • getListingOffers / getItemOfferssku+path 或 asin+path;itemCondition 必填;可选 customerType
  • Item / Listing Offers Batchrequests 数组,默认每项为简化对象(见 references/api.md);1~20 条(FOEP 批量脚本为 最多 40 条)。
  • getCompetitiveSummary 批量:每项需 asinmarketplaceIdincludedData(非空字符串数组);可选 lowestPricedOffersInputs
  • getFeaturedOfferExpectedPriceBatch:每项需 marketplaceIdskusegment(对象,结构以官方为准)。

Scripts

  • get_pricing.py · get_competitive_pricing.py · get_listing_offers.py · get_item_offers.py
  • post_item_offers_batch.py · post_listing_offers_batch.py · post_featured_offer_expected_price_batch.py · post_competitive_summary_batch.py
  • check_auth_dependency.py · _spapi_pricing_common.py(内部模块)
export LINKFOXAGENT_API_KEY="<your-key>"

python scripts/get_item_offers.py '{"sellerId":"A1...","region":"NA","asin":"B0...","marketplaceId":"ATVPDKIKX0DER","itemCondition":"New"}'

python scripts/post_item_offers_batch.py '{"sellerId":"A1...","region":"NA","requests":[{"asin":"B0...","marketplaceId":"ATVPDKIKX0DER","itemCondition":"New"}]}'

Display Rules

  1. MarketplaceId(单数)与 Listings 的 marketplaceIds 勿混用。
  2. 先看网关 errcode / httpStatus,再解析各脚本对应的解析字段(如 itemOffersitemOffersBatchcompetitiveSummary 等)。
  3. POST 类接口:stdout 中含 requestBody(脚本组装的 Amazon 请求体),便于排查。
  4. 白名单:除 products/pricing/... 外,批量路径以 batches/products/pricing/... 开头;1005 时需后端放行对应前缀。
  5. 各接口 Usage plan 不同(尤其 2022-05-01 批量约 0.033 req/s),注意 429

Important Limitations

  • 权限:Product Pricing 及相关角色;部分 2022-05-01 能力可能另有应用内配置要求,以 Amazon 为准。
  • FOEP 批量segment 须符合官方模型;条数上限脚本按 40 校验(与文档「up to 40」一致)。
  • 返回结构以 Amazon schema 为准;详见 references/api.md

积分消耗规则

不消耗积分。
