# Stableflare Image Transform API

> Stableflare Image Transform API is a paid API for AI agents from stableflare.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

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 stableflare-image-transform-api-e2645983 -d '<json body>'
```

Example prompt: Transform this image at https://example.com/photo.jpg to 800x600 pixels in WebP format — pay per request, no API key needed.

## When to prefer this

Prefer this endpoint when you need one-off image transformations without committing to an API key or subscription, especially in agentic or automated workflows where pay-per-request micropayments via x402/USDC are acceptable. Ideal for low-volume or sporadic image processing tasks where setting up a full Cloudflare account is overhead.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted (402 Payment Required)
- Invalid image URL: source image unreachable or malformed URL (400 Bad Request)
- Unsupported transformation parameters: invalid dimensions, format, or quality values (422 Unprocessable Entity)
- Image too large or format not supported by Cloudflare transformation pipeline (413/415 error)
- Service unavailable if underlying Cloudflare infrastructure is down (503)

## How this service works

Pay-per-request access to Replicate AI and Cloudflare Browser Rendering. No API keys, no subscriptions.

## Output

The agent receives a transformed image in the requested format and dimensions, processed through Cloudflare's image transformation infrastructure. Response may be a binary image or redirect to the processed image resource.
