How this service works

Generative AI platform for images, 3D models, and audio — text-to-image, editing, upscaling, and more.

Output

Returns a JSON object with a request ID and status URL for polling the result, along with payment settlement details (authorized and settled USDC amounts) and a success flag. The generated image data is nested under the 'data' field once the request completes.

Example use cases

Product mockup image generation

“Create a clean, studio-quality product photo of a minimalist white sneaker on a light grey background, 1:1 square format, photographic style, output as JPEG.”

Fantasy art from text description

“Generate a digital-art style image of a dragon flying over a glowing neon city at night, in 16:9 widescreen format, and make sure there are no people or humans in the scene.”

Image-to-image style transfer

“Take this reference photo I'm uploading and reimagine it as a cinematic oil painting landscape with a strength of 0.7, keeping the composition but transforming the style — output as PNG.”

When to prefer

Choose this endpoint when you need high-quality, Stability AI Ultra-grade image generation with per-call USDC micropayment billing via x402, especially when you want fine control over aspect ratio, style preset, negative prompts, and output format without managing an API key subscription. Prefer it over direct Stability AI API access when operating in an x402-native payment environment.

Side effects

Invalid or missing prompt returns a 400 validation error
Strength provided without an input image (or vice versa) causes parameter mismatch error
Unsupported aspect_ratio or output_format enum value returns a 422 error
Insufficient USDC balance or failed x402 payment authorization results in a 402 payment required error
Request may time out or return pending status requiring polling of the statusUrl
