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.

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.

Step 2 of 2 · Call the tool

AI Guide

Question

What can Image Upscale produce, and how might I use it?

AI answer

This API starts a task to enlarge an image by a requested factor from 1 to 4, with optional quality enhancement. The supplied response shows task acceptance rather than an enlarged image, and it does not document the completed image fields or achieved dimensions.

Data category	Documented field	What it means
Task reference	`data.taskId`	Identifies the upscaling task to check later.
Progress	`data.status`	Shows the task state; the example shows `PENDING`.
Upscaled result	`data.result`	Is `null` in the pending example. No completed image link or dimension fields are documented.

Enlarge a small product image for a larger listing layout.
- Prompt example: “I am preparing product creative for an online listing. Could you enlarge a small product image for a larger listing layout? Ask me for required source images or text, and show the finished result only after the task completes.”
Request enhanceQuality while upscaling a soft source image, then inspect the completed result.
- Prompt example: “I am preparing product creative for an online listing. Could you request enhanceQuality while upscaling a soft source image, then inspect the completed result? Ask me for required source images or text, and show the finished result only after the task completes.”
