Integration Tips

✓Best Practices

  • • Always include x-api-key header
  • • Always handle errors gracefully
  • • Validate input data before sending
  • • Use HTTPS for secure communication
  • • Cache responses when appropriate

ℹResponse Headers

  • • Content-Type: application/json
  • • x-api-key: Required for authentication
  • • Status codes: 200 (success), 400 (error), 401 (unauthorized)
  • • No rate limiting applied

Rate Limits

⏱️

Request Rate

30req / min

Per API key, per endpoint. Sliding 60-second window.

🔀

Concurrency

3concurrent

Max simultaneous in-flight requests per API key.

Response Headers

X-RateLimit-LimitMaximum requests allowed per minute
X-RateLimit-RemainingRequests remaining in the current window
X-RateLimit-ResetSeconds until the current window resets
Retry-AfterSeconds to wait before retrying (only on 429)

429 Too Many Requests

HTTP/1.1 429 Too Many Requests
Retry-After: 12
X-RateLimit-Limit: 30
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 12

常见问题

覆盖哪些专利局？

全球申请 — USPTO、EPO、WIPO PCT、JPO、KIPO、CNIPA以及主要国家局。搜索运行在统一的语义专利索引之上。

可以按申请人或发明人过滤吗？

将其作为自然语言查询的一部分传入（例如 assignee:Tesla 电池热管理）。语义索引可在查询字符串中解析实体式过滤。

可以按日期范围过滤吗？

可以。start_date / end_date（YYYY-MM-DD）按申请或公开日期过滤。

与USPTO直接搜索相比定价如何？

USPTO的公共搜索免费但仅支持关键词，且没有语义排序。本API以每次调用80积分（约 $0.08 用户成本）运行跨司法辖区的语义搜索 — 在需要排序的、面向LLM的结果时非常有用。

工具Schema？

GET /api/search/patents/tool-schema 返回OpenAI函数与Claude工具使用定义。
