# Venice AI Image Upscale & Enhance

> Venice AI Image Upscale & Enhance is a paid API for AI agents from api.venice.ai, paid per call via x402, $10/call, status unknown (last checked 2026-10-11).

Upscales an image by a configurable scale factor (1–4x) and optionally enhances it with AI-driven style and detail improvements.

## Facts

- Endpoint: POST https://api.venice.ai/api/v1/image/upscale?utm_source=zero.xyz
- Price: $10/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/venice-ai-image-upscale-enhance-6880478f

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 venice-ai-image-upscale-enhance-6880478f -d '<json body>'
```

Example prompt: Can you upscale this image 4x using Venice AI and also run the enhancer on it with a 'cinematic' style and medium creativity (0.5)?

## When to prefer this

Choose this endpoint when you need to increase the resolution of an existing image (up to 4x), optionally combined with AI-driven style enhancement using a text prompt. Ideal when quality preservation matters and you want control over creativity vs. fidelity trade-offs via replication and enhanceCreativity parameters. Prefer over generic resize tools when AI hallucination-avoidance (replication parameter) is important.

## Known failure modes

- Image dimensions below minimum (65,536 pixels) — request rejected
- Final image would exceed 16,777,216 pixels — scale dynamically capped or rejected
- File size exceeds 25MB — request rejected
- scale=1 with enhance=false — invalid combination, request rejected
- 402 Payment Required — insufficient balance, top-up instructions returned
- Invalid base64 encoding — malformed input error
- Unsupported image format — format error

## How this service works

Image upscaling.

## Output

A binary image file containing the upscaled and/or enhanced version of the input image, with dimensions up to the maximum allowed (16,777,216 pixels total). Returned as a binary stream (image file).
