Zhihuiya Patent PDF Downloader

This skill guides you on how to retrieve patent PDF full-text download links from the Zhihuiya patent database, supporting lookup by patent ID or publication number.

Core Concepts

The Zhihuiya Patent PDF service provides direct download links to the full-text PDF documents of patents worldwide. You can query by patent ID or publication number (also called public announcement number), and retrieve up to 100 patents in a single request.

Lookup priority: When both patentId and patentNumber are supplied, the service uses patentId first. This is important to remember when both identifiers are available.

Family substitution: If a patent's own PDF is unavailable, the service can optionally return the PDF of a related family patent instead.

Parameter Guide

Parameter	Type	Required	Description
patentId	string	Conditionally	Patent ID(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries.
patentNumber	string	Conditionally	Publication/announcement number(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries.
replaceByRelated	string	No	Whether to substitute with a family patent PDF when the original is unavailable. 1 = yes, 0 = no. Defaults to no substitution.

How to Choose the Right Identifier

• Patent ID (patentId): An internal numeric identifier within the Zhihuiya system. Use this when the user provides Zhihuiya-specific IDs.
• Publication Number (patentNumber): The public-facing patent number (e.g., US20230012345A1, CN115000000A). Use this when the user provides standard patent numbers.

Response Fields

Field	Description
total	Number of records returned
data	Array of patent objects, each containing download information
data[].patentId	The patent ID
data[].pn	The publication/announcement number
data[].pdfPath	The PDF full-text download URL
data[].pnRelated	Publication number of the substitute family patent (only present when family substitution is used)
costToken	Tokens consumed by the request

调用方式

• API 端点：POST /zhihuiya/pdfData（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/zhihuiya_pdf_data.py '<JSON 参数>' [--inline]
• 成本约束：本工具会消耗积分；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-zhihuiya-pdf-data-<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。

解决认证和积分问题

发生以下异常情况时，采用以下措施来处理：

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。

措施

• 优先采用skill内的 onboarding.md 引导解决问题。
• 如找不到 onboarding.md 文件，则加载 /linkfox-onboarding 这个skill并根据它的引导来处理。如未安装请先安装：
  • 下载 https://agent-files.linkfox.com/skills/linkfox-onboarding/release.zip，解压后安装这个skill。如需用户授权才可下载，要询问用户获得授权，你不能自己放弃下载。
• 兜底措施：仅当前面两个措施经过所有努力都走不通时，才提示用户依据 https://skill.linkfox.com/linkfoxskills/guide.htm 指引获取API Key，或去 https://os.linkfox.com/ 补充积分。

Usage Examples

1. Single Patent by Publication Number

Retrieve the PDF for patent publication number US20230012345A1.

Parameters: {"patentNumber": "US20230012345A1"}

2. Multiple Patents by Publication Number

Download PDFs for CN115000000A, CN115000001A, and CN115000002A.

Parameters: {"patentNumber": "CN115000000A,CN115000001A,CN115000002A"}

3. Single Patent by Patent ID

Get the full-text PDF for patent ID 12345678.

Parameters: {"patentId": "12345678"}

4. With Family Substitution Enabled

Download the PDF for EP4000000A1. If it is unavailable, use a family patent PDF instead.

Parameters: {"patentNumber": "EP4000000A1", "replaceByRelated": "1"}

5. Batch Download by Patent IDs

Retrieve PDFs for patent IDs 11111111, 22222222, 33333333.

Parameters: {"patentId": "11111111,22222222,33333333"}

Display Rules

1. Present download links clearly: For each patent, show the publication number and its PDF download link in a clean table or list format.
2. Highlight substitutions: If a PDF was provided via family patent substitution, explicitly note this and show the pnRelated value so the user knows which family patent was used.
3. Batch results: When multiple patents are returned, present them in a table with columns: Publication Number, Patent ID, PDF Link, and Substitution Note (if applicable).
4. Error handling: When a query fails or returns no results, explain the reason and suggest the user verify the patent ID or publication number. If replaceByRelated was not enabled, suggest enabling it as an alternative.
5. No PDF available: If a patent entry is returned without a pdfPath, inform the user that the PDF is not available and suggest enabling family substitution.

Important Limitations

• Batch limit: A maximum of 100 patents per request.
• Identifier requirement: At least one of patentId or patentNumber must be provided; the request will fail if both are empty.
• Priority rule: When both identifiers are provided, patentId takes precedence over patentNumber.
• PDF availability: Not all patents have PDFs available. Use the replaceByRelated option to fall back to family patents.

User Expression & Scenario Quick Reference

Applicable -- Patent PDF document retrieval tasks:

User Says	Scenario
"Download the PDF for patent XX"	Single patent PDF retrieval
"Get full-text documents for these patents"	Batch patent PDF download
"I need the PDF for publication number XX"	Lookup by publication number
"Can I get the patent document even if it's not directly available"	Family substitution scenario
"Batch export patent PDFs"	Multi-patent batch download

Not applicable -- Needs beyond patent PDF retrieval:

• Patent search or discovery (finding patents by keyword, assignee, etc.)
• Patent citation or legal status analysis
• Patent claim interpretation or translation
• Patent portfolio analytics or landscape mapping

积分消耗规则

按动态规则计费：消耗积分 = 81 × 返回data条数。每条为 1 条专利 PDF 结果

重要：本技能的服务按倍数动态计算，可能一次性消耗大量积分，必须提醒用户，由用户决定是否继续。
