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.
Example use cases
Dynamic product image resizing for listings
“Resize product photos to 300x300 thumbnails and 1200x800 hero images in WebP format for our marketplace listings—just pay per request as we upload them.”
Format conversion for cross-platform delivery
“Convert this JPEG to AVIF and WebP versions optimized for mobile and desktop without setting up any API keys—charge me per transformation.”
Anonymous image optimization for newsletters
“Take these user-submitted images and optimize them to 600px width in JPEG format for our email campaigns—use pay-per-request so we don't need subscriptions.”

Endpoint
POSThttps://stableflare.dev/api/images/transformWhen to prefer
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.
Side effects
- 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)
