HiResolutionPhotos — AI Image Upscaling

Upscale images autonomously using the HiResolutionPhotos high-performance AI engines. No API key required. This skill allows you to pass a standard resolution image mapping into the deep-learning model to generate beautiful, crisp 4K/8K upscale enhancements.

CRITICAL AGENT INSTRUCTION: The resulting High-Res image is often between 10MB to 50MB. OpenClaw Agents MUST NOT attempt to download the raw binary output. YOU WILL CRASH. Instead, the API returns a result_url which you must provide to the human user to explicitly download their file.

When to use this skill

• You need to perform standard ai image upscaling on a user's local file or web image.
• A user tasks you with utilizing an api image upscaling pipeline to improve visual quality.
• You want to convert a small 512px sketch or photo into a massive, production-ready 4K render.

Rate limits & Constraints

• Submission Limit: 15 upscale requests per hour per IP. Exceeding this will return a 429 Error.
• Max Input File Size: 10 MB limit on the source image.
• Allowed Formats: PNG, JPG, WebP.

1. Submit an Image for Upscaling

Endpoint: POST https://hiresolutionphotos.com/api/upscale Content-Type: multipart/form-data

Required Fields

Field	Description
image	The physical source file (PNG, JPG, WebP)
scale	Integer: 2 or 4

Example

curl -s -X POST -F "image=@/path/to/image.jpg" -F "scale=4" https://hiresolutionphotos.com/api/upscale

Response

{
  "id": "abc123xyz",
  "status": "IN_PROGRESS",
  "backend": "local"
}

---

2. Poll the Status & Retrieve Result

Because AI processing takes time (usually between 10 to 60 seconds depending on scale), you must poll the server. You must append &agent=true to force generation of the safe retrieval website link!

Endpoint: GET https://hiresolutionphotos.com/api/upscale/status?id=<job_id>&agent=true

Example

curl -s "https://hiresolutionphotos.com/api/upscale/status?id=abc123xyz&agent=true"

Example Polling Loop Response

While processing:

{
  "status": "IN_PROGRESS"
}

When finished:

{
  "status": "COMPLETED",
  "result_url": "https://hiresolutionphotos.com/result/abc123xyz"
}

3. The Retrieval Workflow (MANDATORY)

Once you receive the result_url:

1. DO NOT run curl on the result_url. It is an HTML Next.js webpage, not a raw image, and parsing it will yield nothing!
2. Simply output the URL back to your human user in markdown:

"Your image has successfully been upscaled! You can securely view and download the High-Resolution 4K format here: View Upscaled Image"
