What this API does

Find visually similar utility-model patents from an image URL with country, legal-status, date, assignee, shape, pattern. The request accepts url, patentType, model, country, loc. Its documented result includes allRecordsCount, apdt, apno, authority, currentAssignee, imgId, inventor, loc.

Utility Patent Image Search API use cases

Investigate a product IP question

To investigate a product ip question, a compliance analyst submits url and patentType to Utility Patent Image Search. The returned allRecordsCount, apdt, apno help identify records relevant to the proposed product.

Collect records for an IP review

A compliance analyst uses Utility Patent Image Search with url and patentType to collect records for an ip review. The returned allRecordsCount, apdt, apno help collect bibliographic evidence for a specialist review.

Document evidence for specialist assessment

For this workflow, a compliance analyst calls Utility Patent Image Search with url and patentType to document evidence for specialist assessment. The result helps document the records supporting an IP research question.

Utility Patent Image Search API FAQ

What does the Utility Patent Image Search API return?

Find visually similar utility-model patents from an image URL with country, legal-status, date, assignee, shape, pattern. The documented output includes allRecordsCount, apdt, apno, authority, currentAssignee, imgId, inventor, loc. It corresponds to the supplied url, patentType, model, country, loc. Optional fields can be absent; a missing value should not be interpreted as a measured zero. Example values illustrate the response shape, rather than live account results.

How many credits does the Utility Patent Image Search API cost?

The current documented cost is 112 credits / call. This is the same cost shown at the top of this page. If a range or estimate is displayed, the final charge depends on the request. Review your available credits and the pricing page before calling the API, and check API usage records for the actual charge.

How do I call the Utility Patent Image Search API from my app or an MCP client?

Send a POST request to https://api.nexscope.ai/api/skill-api/v1/skills/zhihuiya-utility-patent-image-search/run with your API key as a Bearer token and the JSON inputs shown in API integration. In a compatible MCP client such as Claude or Cursor, connect Nexscope and call nexscope_zhihuiya_utility_patent_image_search. Use the MCP arguments shown in the MCP guide, or switch Online test to MCP to review its request before adding it to your app.

HTTP status codes

Code	Description
200	Default HTTP response for both success and many business errors. Only outer JSON code 0 indicates success or asynchronous acceptance; inspect data for the result.
429	Execution admission rate limit; honor Retry-After when present.
503	Execution admission is temporarily unavailable; honor Retry-After when present.
Opt-in	X-Nexscope-Http-Status: semantic maps controller-handled business errors to HTTP status on run and task routes. Pre-authentication failures, such as a missing API key (code 11209), may still return HTTP 200 before this mapping. Always check the outer JSON code; malformed requests and infrastructure failures may also return non-200 HTTP responses.

Data source, freshness, and limitations

Source, freshness, coverage, rate limits, and estimation notes are not specified in this API definition unless they appear in the request or response field documentation above. Do not assume official marketplace data or real-time freshness when it is not explicitly documented.

Step 1 of 2 · Connect your MCP client

MCP

V2 recommended

Connect remote agents through the standard MCP 2025-11-25 Streamable HTTP endpoint. Use OAuth 2.1 Authorization Code with PKCE, or an API key for compatibility.

POST https://api.nexscope.ai/mcp
MCP-Protocol-Version: 2025-11-25
Content-Type: application/json

Authentication

OAuth clients request the mcp:tools scope. The endpoint's 401 response advertises protected-resource metadata for authorization discovery.
