# x402.agentutility.ai Image Upscale

> x402.agentutility.ai Image Upscale is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Upscales a source image 2x or 4x using Venice's super-resolution model and returns a permanent fal-hosted URL to the enlarged image.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-agentutility-ai-image-upscale-1352e5c7 -d '<json body>'
```

Example prompt: Can you upscale this image to 4x resolution using Venice's super-resolution model? Here's the URL: https://example.com/my-photo.jpg — I need the sharpened, enlarged version back as a permanent link.

## When to prefer this

Choose this endpoint when you need AI-powered super-resolution (2x or 4x) on an existing image and want a permanent hosted URL in return. It is ideal for agents that need to enlarge product photos, AI-generated art, or low-resolution assets without managing GPU infrastructure. Prefer it over generic image transformation tools when Venice's SD3.5-based upscaler quality is needed and USDC micropayment settlement is acceptable.

## Known failure modes

- Image URL is not publicly accessible or returns a non-2xx status — endpoint cannot fetch the source image
- Unsupported scale value (anything other than 2 or 4) returns a validation error
- Source image format not supported by the Venice upscaler
- Venice or fal.media service unavailability causes a timeout or 5xx error
- Payment via x402/USDC not settled before request — call is rejected

## How this service works

Upscales an image 2x or 4x via Venice's image/upscale endpoint (default model: venice-sd35). Returns a permanent fal-hosted URL. Use it as a super-resolution tool to sharpen or enlarge an image without loss.

## Output

A JSON object containing the permanent fal.media-hosted URL of the upscaled image, the model used (e.g. venice-sd35), the scale factor applied (2 or 4), the source identifier ('venice'), and a Venice request ID for traceability.
