Step 1 of 3 · Authenticate

Authentication

All run endpoints require a user API key. Send it as a bearer token in the Authorization header.

Authorization: Bearer nk-xxxxxxxxxxxxxxxxx

Missing or invalid API keys return an authentication error. Manage keys from .

Step 2 of 3 · Send a request

POSThttps://api.nexscope.ai/zy/descriptionData

Run an API

Send a JSON request body using the parameters described below.

Example request

Replace YOUR_API_KEY, then run this command in your terminal.

curl -X POST 'https://api.nexscope.ai/zy/descriptionData' \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

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 or invalid API key (code 11209, including an incomplete or corrupted copy) or an expired website login session (code 12001), 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.

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.

Question

What can Patent Technical Description give me, and when would I use it?

AI answer

Patent Technical Description retrieves the documented description content for a patent identified by ID or publication number. The response models that content as an array; the example shows an empty array, so it does not establish the structure of individual sections.

Data category	Documented fields	What the values mean
Technical description	`description`	An array containing the patent's description content when available. The schema does not specify the format of its elements.
Patent identification	`patentId`, `pn`	The patent ID and publication number associated with the returned description.
Family substitution	`pnRelated`	The publication number of the related patent used when a requested family substitution occurs.

Read the available description for a known patent while evaluating its disclosed technical approach.
- Prompt example: “I am researching a product design before launch. Could you read the available description for a known patent while evaluating its disclosed technical approach? Show the relevant returned evidence and tell me what input you need from me.”
Retrieve descriptions for a set of identified patents for side-by-side research.
- Prompt example: “I am researching a product design before launch. Could you retrieve descriptions for a set of identified patents for side-by-side research? Show the relevant returned evidence and tell me what input you need from me.”
Request replaceByRelated when a patent's own description is unavailable, then check pnRelated to see whether a family patent supplied the content.
- Prompt example: “I am researching a product design before launch. Could you request replaceByRelated when a patent's own description is unavailable, then check pnRelated to see whether a family patent supplied the content? Show the relevant returned evidence and tell me what input you need from me.”

An empty description array, as in the example, provides no technical text to analyze.
