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.

AI Guide

Question

What data can Website Resource Status provide, and how might I use it?

AI answer

Website Resource Status returns observations about resources found in a website crawl, with an optional page URL filter. It can help inspect images, scripts, and stylesheets associated with crawled pages.

Data category	Documented fields	What the values mean
Resource identity	`data.result.items[].url`	The observed resource URL.
Resource kind	`data.result.items[].resourceType`	A classification such as `SCRIPT`, `IMAGE`, `STYLESHEET`, `BROKEN`, or `UNKNOWN`.
Response status	`data.result.items[].providerStatusCode`	The resource's observed HTTP status code, when available.
Transfer size	`data.result.items[].sizeBytes`	The reported resource size in bytes, when available.
Load duration	`data.result.items[].loadDurationMs`	The reported load duration in milliseconds, when available.
Coverage and gaps	`data.result.coverage.returnedCount`, `data.result.coverage.truncated`, `data.result.missingFields[].reason`	How many records were returned, whether the sample was truncated, and reasons for missing data.

Find resource URLs with error status codes for investigation.
- Prompt example: “I am reviewing an ecommerce website. Could you find resource URLs with error status codes for investigation? Show matching records and source links where the API provides them; ask me for any required identifier or filter.”
Review large image or script records when assessing page weight.
- Prompt example: “I am reviewing an ecommerce website. Could you review large image or script records when assessing page weight? Show the relevant returned evidence and tell me what input you need from me.”
Compare reported load durations among observed resources to spot slow candidates.
- Prompt example: “I am reviewing an ecommerce website. Could you compare reported load durations among observed resources to spot slow candidates? Show the returned values behind the comparison, and mark missing data.”
Filter to a page URL and inspect which resource types appeared in its crawl results.
- Prompt example: “I am reviewing an ecommerce website. Could you filter to a page URL and inspect which resource types appeared in its crawl results? Show matching records and source links where the API provides them; ask me for any required identifier or filter.”

These are sampled resource observations. A null status, size, or duration means that value was not reported; it should not be treated as a successful load or zero.
