Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/legal/patents?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured patent data (IDs, titles, grant dates, types, assignees) for a named US organization or individual inventor, especially in legal research, competitive intelligence, or IP due diligence workflows. Prefer this over full-text patent search tools when you need clean, structured grant-level metadata rather than full patent documents.
Side effects
- No patents found for the given name — returns empty list
- Ambiguous or misspelled assignee/inventor name resulting in zero or incorrect matches
- Rate limiting or payment failure due to x402 micropayment not completing
- Service unavailability returning a non-200 HTTP status
