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 Image Copyright Check tell me about an image, and when would I use it?

AI answer

Image Copyright Check compares a submitted image with recorded works and returns potential matches for review. Similarity and radar findings are screening signals, not a legal determination or proof that every relevant work was searched.

Data category	Documented field names	What the values mean
Match volume	`total`, `data`	The reported number of records and the list of returned matches.
Matched work imagery	`path`, `pathThumb`	Paths to a matched work image and its thumbnail, when supplied.
Visual similarity	`similarity`	The reported similarity for a match.
Radar assessment	`subRadarResult`	`1` indicates an infringement finding, `0` indicates no infringement finding, and `null` means no radar detection.
Source and rights holder	`copyrightUrl`, `copyrightCode`, `rightsOwner`, `link`	Source, identification code, reported rights holder, and official-site link when available.
TRO indicators	`troCase`, `troHolder`	Whether a TRO rights-protection history or TRO rights holder is flagged.

Screen a proposed listing image for similar recorded works before publication.
- Prompt example: “I am checking potential intellectual-property issues for a product. Could you screen a proposed listing image for similar recorded works before publication? Show the relevant returned evidence and tell me what input you need from me.”
Open the matched image and source details to review a high-similarity result.
- Prompt example: “I am checking potential intellectual-property issues for a product. Could you open the matched image and source details to review a high-similarity result? Show the relevant returned evidence and tell me what input you need from me.”
Route matches with a radar finding or TRO indicator for closer rights review.
- Prompt example: “I am checking potential intellectual-property issues for a product. Could you route matches with a radar finding or TRO indicator for closer rights review? Show the relevant returned evidence and tell me what input you need from me.”
Record the reported rights holder and copyright code when preparing a manual investigation.
- Prompt example: “I am checking potential intellectual-property issues for a product. Could you record the reported rights holder and copyright code when preparing a manual investigation? Show the relevant returned evidence and tell me what input you need from me.”
